Radiation Protection Program Revision 17
1 Radiation Safety Policy and Company Description
1.1 Clive Facility Radiation Protection Program
1.1.1 Purpose
The Radiation Protection Program (hereinafter referred to as "RPP" or
program) has been developed to establish Clive Facility requirements' to
receive, possess, process, use, transfer or dispose of licensed radioactive
material. The Clive Facility is committed to managing its operations
involving exposure to ionizing radiation and radioactive materials by
incorporating the philosophy that such doses should be "As Low As
Reasonably Achievable" (ALARA).
The RPP establishes the measures that Clive Facility management will use
to ensure that appropriate regulatory requirements and Clive Facility
policies, programs and procedures are met.
1.1.2 Program Applicability and Control
1.1.2.1 Clive Facility employees, escorted individuals, and
contractors shall meet the requirements of this program.
1.1.2.2 This program shall be reviewed each calendar year to
identify necessary changes as a result of changes in
regulations, lessons learned, and suggestions for
improvement. Changes shall be approved by the Clive
Radiation Safety Officer (RSO) who will verify that this
program remains consistent with the EnergySolutions '
Radiation Safety Program (ES-RS-PG-001), existing
permits, statutory and regulatory requirements, and U.S.
Nuclear Regulatory Commission (NRC) or State of Utah,
Division of Waste Management and Radiation Control
(DWMRC) directives. Deviation from this program
requires the written approval of the RSO.
1.1.2.3 The RSO may delegate in writing any or all of the work to
others. Responsibility, however, cannot be delegated. The
RSO, as applicable, retains responsibility for conformance
to radiation safety requirements for the delegated activity.
1.1.2.4 The RPP includes the Radiation Safety implementing
procedures and the ALARA Program.
1.1.3 Compliance
1.1.3.1 The word "shall" identifies those elements and
requirements that have been considered and found by Clive
management to be mandatory unless prior approval of an
alternative approach is obtained by the appropriate
regulatory agency and/or management.
Page 6 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
1.1.3.2 The use of "should" recognizes that there may be
situational attributes that warrant special treatment and
permits alterations to achieve the desired level of radiation
control performance.
1.1.3.3 The word "may" means Clive management has identified
an acceptable action but management is allowed to select
alternative methods.
1.2 Clive Facility Summary
1.2.1 Site Description
EnergySolutions is a nuclear services company with its corporate office
located at 299 South Main Street, 17th Floor, in Salt Lake City, Utah. The
Clive Facility is a radioactive/mixed waste treatment and disposal site at
Clive, Utah that is approximately three miles south of interstate 1-80 at
exit 49 in the western Utah desert.
1.2.2 Waste Licensing
The Clive Facility has two radioactive materials licenses for the disposal
of radioactive material. A license issued by the Utah Division of Waste
Management and Radiation Control (DWMRC) for disposal of Class A
Low Level Radioactive Waste (LLRW), Naturally Occurring Radioactive
Material or Accelerator-Produced Radioactive Material (NARM), source
material, special nuclear material, mixed waste (radioactive hazardous)
and 11e.(1) byproduct material. The second license is issued by the
DWMRC to permit the disposal of 1le.(2) byproduct material resulting
from the extraction of uranium or thorium from ore.
Permits from DWMRC as well as other regulatory agencies involved in
site operations include:
• DWMRC for hazardous waste treatment, storage, and disposal.
• The Utah Division of Water Quality for protection of ground
waters.
• The Utah Division of Air Quality to ensure precautions are taken
to minimize dust hazards.
1.3 Definitions
1.3.1 Access Control Points are designated areas established for normal
personnel and personal item entrance and egress from the restricted area.
1.3.2 Airborne radioactivity area means a room, enclosure, or area in which
airborne radioactive materials, composed wholly or partly of licensed
material, exist in concentrations-
• In excess of the derived air concentrations (DACs) specified in
appendix B, to 10 CFR 20 .1001-20.2401 or derived from values in
Page 7 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
ICRP 68. To such a degree that an individual present in the area
without respiratory protective equipment could exceed, during the
hours an individual is present in a week, an intake of 0.6 percent of
the annual limit on intake (ALI) or 12 DAC-hours.
1.3.3 Controlled area means an area, outside of a restricted area but inside the
site boundary. This is an area that Clive management can limit access for
any reason.
1.3.4 Individual Monitoring Devices means devices designed to be worn by a
single individual for the assessment of dose equivalent such as film
badges, thennoluminescent dosimeters (TLD'S) or equivalent, electronic
dosimeters and personal ("lapel") air sampling devices.
1.3.5 Personnel Contamination Event (PCE) means radioactive contamination,
above specified limits, on skin, hair or personnel clothing.
1.3.6 Restricted area (RA) is an area within the controlled area, access to which
is limited for the purpose of protecting individuals from undue risks from
exposure to radiation and radioactive materials. The restricted area
boundary is posted "Caution Radioactive Material" and is bordered by a 6-
foot high fence (minimum height 5'9").
1.3.7 Tissue weighting factor (WT), for an organ or tissue (T) is the proportion of
the risk of stochastic effects resulting from irradiation of that organ or
tissue to the total risk of stochastic effects when the whole body is
irradiated uniformly. For calculating the effective dose equivalent, the
values of wT. are from ICRP 68.

thymus, adrenal, pancreas, extra thoracic airways). The weighting
factor for each remaining organ or tissue is 0.05.
b. For the case of uniform external irradiation of the whole body, a
weighting factor (WT) equal to 1 may be used in determination of
the effective dose equivalent.
Note: In addition to the definitions above, the Clive
Facility recognizes the regulatory definitions
contained in reference 8.14

2.1.2.5 The woman who is pregnant or suspects she is pregnant is
responsible for declaring the pregnancy to initiate the dose
restrictions detailed in this section. The declaration with
the estimated date of conception shall be made in writing to
the RSO. Such a declaration shall not result in a change in
job status.
2.1.2.6 The dose restrictions for a person who has declared
pregnancy remains in effect until it is withdrawn in writing
or until the woman is no longer pregnant.
2.1.2.7 If the dose equivalent to the embryo/fetus exceeds 0.5 rem,
or is within 0.05 rem of this dose, by the time the woman
declares a pregnancy, Clive management shall be in
compliance with section 2.1.2.1 if the additional dose to the
embryo/fetus does not exceed 0.05 rem during the
remainder of the pregnancy.
2.1.2.8 Upon notification of pregnancy, the worker shall be
informed of the risks of anticipated radiation dose to the
embryo/fetus and efforts shall be made to avoid substantial
variation above a uniform monthly dose rate for the
remainder of the gestation period.

• The procedures to be followed to maintain dose
ALARA.
2.1.3.4 Concentrations of radioactive material, which may be
released to the general environment in ground water,
surface water, air, soil, plants, or animals, must not result in
an annual dose exceeding an equivalent of 25 millirems to
the whole body, 75 millirems to the thyroid and 25
millirems to any other organ of any members of the public.
Reasonable effort should be made to maintain releases of
radioactivity to the environment as low as reasonably
achievable.
2.1.3.5 A constraint on air emissions of radioactive material to the
environment, excluding radon-222 and its daughters, shall
be established by the Clive Facility; such that, the
individual member of the public likely to receive the
highest dose will not be expected to receive a TEDE of 10
mrem (0.1 mSv).
2.1.3.6 The Clive Facility is authorized to use ALI, DAC and
Environmental Control Limit (ECL) values based on dose
coefficients adopted by ICRP Publication 68 and 72.
2.1.4 Planned Special Exposure
EnergySolutions does not anticipate authorizing planned special exposures
at the Clive facility. However, in exceptional situations, EnergySolutions
employees may receive doses (planned special exposures) separate from
and in addition to the annual occupational dose limits. All Planned Special
Exposures (PSE's) shall (1) receive prior written authorization from the
Business Group President and the Corporate Radiation Safety Officer and
(2) comply with all Federal or State regulations.
Note: Prior to participating in a planned special exposure an

Notes:
a. Where surface contamination by both alpha- and beta-gamma
emitting nuclides exist, the limits established for alpha- and beta-
gamma emitting nuclides should apply independently.
b. As used in this table, dpm (disintegrations per minute) means the rate
of emission by radioactive material as determined by correcting the
counts per minute observed by an appropriate detector for
background, efficiency and geometric factors associated with the
instrumentation.
Page 14 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
c. Measurements of average contaminant should not be averaged over
more than one square meter. For objects of less surface area, the
average should be derived for each such object.
d. The maximum contamination level applies to an area of not more
than 100 cm2.
e. The amount of removable radioactive material per 100 cm2 of surface
area should be determined by wiping the area with dry filter or soft
absorbent paper, applying moderate pressure, and assessing the
amount of radioactive material on the wipe with an appropriate
instrument of know efficiency. When removable contamination on
objects of less surface area is determined, the pertinent levels should
be reduced proportionally and the entire surface should be wiped.
f. The average and maximum radiation levels associated with surface
contamination resulting from beta-gamma emitters shall not exceed
0.2 mrem/hr at 1 cm and 1.0 mrem/hr at 1 cm, respectively.
2.2.1.3 Personal items, materials and personnel exiting the
Restricted Area are surveyed for both alpha and beta
emitting nuclides.
Alpha limits are less than 100 dpm/100 cm2 for skin,
clothing, materials, and surfaces; and less than 300
dpm/100 cm2 for the soles of shoes.
Beta limit is less than 1,000 dpm/100 cm2 skin, clothing,
materials, surfaces and the soles of shoes.
Other localized areas on personnel or items may be
released to the maximum limits specified in Table 2-1 as
approved by the RSO on a case by case basis and
documented in accordance with CL-RS-PR-115,
Radiological Surveys.
2.2.1.4 Skin or personal clothing shall promptly be decontaminated
and/or removed if radioactive contamination, from other
than noble gases or natural background radioactivity, is
found to exceed these limits.
2.2.1.5 Personnel shall be advised that any measurable
contamination on their person is excessive and the goal is
to keep such contamination below detectable levels.
2.2.1.6 Personnel Contamination Events (PCEs) shall be
documented and the CRSO shall be notified.
2.2.2 Contamination Control Levels
2.2.2.1 Areas having accessible surface contamination above the
limits listed in Table 2-2, Acceptable Surface
Page 15 of 67
EnergySolutions' Clive Facility CL-RS-PG-002

Contamination Levels shall be posted as detailed in section
2.3.1.
2.2.2.2 Contamination in Restricted Areas shall be controlled to
minimize the potential for personal contamination and
elevated airborne radioactivity levels.
2.2.3 Unrestricted Release
2.2.3.1 Unrestricted release shall be used for all vehicles, materials
and equipment leaving the Restricted Area except where
release to Department of Transportation standards is
permitted as described in section 4.2.1.

management shall determine the occupational radiation
dose received during the current year. To comply with
these requirements Clive management may:
• Accept, as a record of the occupational dose that the
individual received during the current year, a
written signed statement from the individual, or
from the individual's most recent employer for work
involving radiation dose, that discloses the nature
and the amount of any occupational dose that the
individual may have received during the current
year;
• Obtain reports of the individual's dose equivalent(s)
from the most recent employer for work involving
radiation dose or the individual's current employer
(if the individual is not employed by
EnergySolutions) by telephone, telegram, electronic
media, or letter. A written verification of the dose
data shall be required if the authenticity of the
transmitted report cannot be established.
5.1.5.2 The record of dose history for the current year required by
section 5.1.5.1 shall be recorded on NRC Form 4, or other
clear and legible records containing all the information
required by Form 4. The form or record must show each
period during the year in which the individual received
occupational dose to radiation or radioactive material and
must be signed by the individual who received the dose.
5.1.5.3 If Clive management is unable to obtain an individual's
current occupational dose, Clive management shall control
occupational dose to a:
• TEDE of 100 mrem (1.0 mSv) per year
Page 36 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
5.1.6 Visitors
5.1.6.1 Visitors who have the potential to receive greater than 10
mrem TEDE during a quarter shall use an electronic
dosimeter to verify dose.
5.1.6.2 All doses, including zero, shall be documented for entry in
the person's dose record.
5.2 Internal Dosimetry
5.2.1 Determination of Internal Dose
Note: The Clive Facility is authorized to use ALI, DAC and
ECL values based on dose coefficients adopted by ICRP
Publication 68 and 72.
5.2.1.1 Exposures to radiation and radioactive material shall be
monitored at levels sufficient to demonstrate compliance
with the dose limits listed in Section 2.1. As a minimum,
the occupational intake of radioactive material shall be
monitored and the CEDE assessed to:
• Adults likely to receive in one year an intake in
excess of 10 percent of the applicable ALI(s) found
in table 1, Columns 1 and 2 of appendix B to 10
CFR 20.1001-20.2401; and
• Minors or declared pregnant women when the
CEDE is likely to exceed 0.1 rem.
5.2.1.2 If the only intake of radionuclides is by inhalation, the total
effective dose equivalent limit is not exceeded if:
EDE + D, =1 TE'DEL
where:
EDE = Effective dose equivalent.
TEDEL = Total effective dose equivalent limit as listed in
Section 2.1.
DL = One of the following:
• The sum of the fractions of the inhalation ALI for
each radionuclide, or
• The total number of derived air concentration-hours
(DAC-hours) for all radionuclides divided by 2,000,
or
Page 37 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
• The sum of the calculated committed effective dose
equivalents to all significantly irradiated organs or
tissues calculated from bioassay data using
appropriate biological models and expressed as a
fraction of the annual limit of 50 rem.
5.2.1.3 For the purpose of determining dose suitable and timely
measurements shall be taken of:
• Airborne radioactivity concentrations in work areas;
Or
• Quantities of radionuclides in the body; or
• Quantities for radionuclides excreted from the body;
or a
• Combinations of these measurements, as needed to
account for and determine compliance with
occupational dose limits.
5.2.1.4 Unless respirators are properly used, it shall be assumed
that an individual inhales airborne radioactive material at
the airborne radioactivity concentration in which the
individual is present. When a respirator is used inhalation
dose shall be calculated pursuant to section 5.2.2.1.
5.2.1.5 The physical and chemical form of the radionuclides will
be used to determine the appropriate lung clearance class
(e.g. S, M, F). If this is not known, the most restrictive
clearance class shall be used. When calculating internal
dose due to Rn-222 and Rn-220, the "with daughters
removed" DAC value should be used when determining
outside dose (Rn-220 requires this assumption to be
confirmed using environmental working level
measurements). The "without daughters removed" DAC
values shall be used when determining inside Rti-222 and
Rn-220 values.
5.2.1.6 For a mixture of airborne radionuclides, the dose
determination may disregard certain radionuclides in the
mixture if:
• the total activity of the mixture is compared with
the most restrictive DAC concentration to
demonstrate compliance with section 2.1.1 dose
limits,
• the concentration of any radionuclide disregarded is
less than 10% of its DAC, and
Page 38 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
• the sum of these percentages for all of the
radionuclides disregarded in the mixture does not
exceed 30 percent.
5.2.1.7 The dose from oral ingestion shall be calculated and
recorded for demonstrating compliance with regulatory
limits where it is suspected and found that oral ingestion
exceeded 10 percent of the applicable oral ALI in a
calendar year.
5.2.1.8 Intake through wounds or absorption through skin shall be
evaluated and accounted for to the extent that it is practical.
5.2.1.9 When specific information on the physical and biochemical
properties of the radionuclides taken into the body or the
behavior of the material in an individual is known, it is
permissible:
• To use that information to calculate the CEDE, this
information shall be documented in the individuals
record; and
• Upon DWMRC approval, adjust the DAC or ALI
values to reflect the actual physical and chemical
characteristics of airborne radioactive material; and
• To separately assess the contribution of fractional
intakes of Class S, M, or F compounds of a given
radionuclide to the CEDE.
5.2.1.10 If the identity of each radionuclide in a mixture is known,
but the concentration of one or more of the radionuclide in
the mixture is not known, the DAC for the mixture shall be
the most restrictive DAC of any radionuclide in the
mixture.
5.2.2 Committed Effective Dose Equivalent (CEDE) Calculation
5.2.2.1 DAC-hours calculation
C 1 DAC —hours(mrem)= *t * DAC APF
where:
DAC-hours = ALI/2000
C = Airborne concentration of radionuclides in which the
individual is present in uCi/m1
DAC = Derived Air Concentration (Stochastic) in uCilml
from 10 CFR [20.1001-20.2401] Appendix B or equivalent.
Page 39 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
CDE calculation will be required when the non-stochastic
DAC is found more limiting.
t = time of dose in hours
APF = Assigned Protection Factors found in 10CFR20
Appendix A (APF is 1 when respirators were not used.)
• C/DAC shall be determined using either of the
following equations when airborne radioactivity
comprises more than one radionuclide:
C C
DAC — ,:+4 DAC,
where:
Ci =Airborne concentration for each radionuclide in
uCi/ml.
DACi = Derived Air Concentration in uCi/m1 for the
applicable radionuclide in uCi/ml.
n = the total number of radionuclides making up the
airborne radioactivity.
or,
C C
DAC DAC R
where:
C = airborne concentration of radionuclides in uCi/m1
DACR = DAC of most restrictive clearance class for each
radionuclide in the mixture.
5.2.2.2 The Committed Effective Dose Equivalent (CEDE) will be
calculated using the following equation.
5000 mrem CEDE(mrem) = DAC — hours
where:
CEDE = Committed Effective Dose Equivalent (mrem)
DAC-hours = Derived Air Concentration - hours
5.2.3 Committed Dose Equivalent (CDE) Calculation
The CDE for the applicable organs shall be calculated as detailed in 10
CFR [20.1001-20.2401], Appendix B.

Radiation Protection Program Revision 17
5.2.4 Calculation of Internal Dose from Intake through Wounds or Skin
Absorption
Protective clothing normally protects against radioactivity intake through
wounds and skin absorption. Should an accident result in an open wound,
the RSO will inform the attending physician of the fact and will supply
guidance effecting the removal or reduction of the amount of radioactive
material remaining in the wound. The RSO will perform an investigation
and estimate the intake using data from wound monitoring or other
available information.
The CDE to any organ will be estimated using methods similar to those
used in NCRP Report 111, Developing Radiation Emergency Plans for
Academic, Medical or Industrial Facilities, August, 1991. Table 4.2 of
that publication provides values of maximum committed dose equivalent
to any organ for adults per unit intake.
5.3 Radiation Monitoring and Surveys
5.3.1 Requirements
5.3.1.1 Surveys shall be taken, as is reasonable, to evaluate
radiation levels, the concentration or quantities of
radioactive material, and the potential radiological hazards
that may be present.
5.3.1.2 Instruments used to perform radiation surveys shall be
constancy checked daily. When constancy checks are not
within ±20 percent of the expected value, the instrument

measurements of the general area, dose rates at a distance
of 30 centimeters from a source or surface of interest to
evaluate potential whole body doses, and dose rates on
contact with potential sources of radiation where there is a
potential for hands-on work.

levels. It is permissible to use direct frisk measurements to
verify the maximum removable contamination on a surface.
5.3.3.4 Items with inaccessible surfaces, which were located in
known or suspected contamination areas and had the
potential to become contaminated at levels likely to exceed
Table 2-1, Acceptable Surface Contamination Levels
values, shall be treated as potentially contaminated and
Page 43 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
subject to administrative controls unless the items are
dismantled and monitored or special survey techniques are
used to survey all surfaces.
5.3.3.5 Swipe surveys for removable contamination shall be
reported in units of disintegrations per minute (dpm) per
100 cm2 (dpm/100 cm2). Swipes of areas less than 100 cm'
shall be reported in dpm per area swiped.

supplement standard swipe techniques in areas generally
assumed not to be contaminated.
5.3.4 Airborne Radioactivity Monitoring
5.3.4.1 Radon and thoron measurements shall be taken as specified
in the radioactive material license(s) and the Environmental
Monitoring Plan. Rad Trak radon and thoron results may
be supplemented by grab samples.
5.3.4.2 Grab samples shall use the modified Kusnetz method or
other approved method to measure Rn-222 WL
concentrations with sample collection volumes and
counting times sufficient to provide a lower limit of
detection (sensitivity) of better than 0.03 WL (See NRC
Regulatory Guide 8.30, "Health Physics Surveys in
Uranium Mills" and the references cited therein).
Corrections for the presence of Radon-220 daughters may
be required using the procedure given in Radiation
Monitoring, by R. L. Rock and Robert T. Beckman, Mine
Safety and Health Administration, U. S. Department of
Labor. Instant WL meters or continuous WL monitors may
be used only if the equivalent sensitivity can be achieved.
5.3.4.3 Air sample program requirements used to measure
occupational exposure should be capable of measuring
airborne contamination concentrations for the most
restrictive radionuclide at 10 percent of the DAC. The use
of respirators may be necessary to meet this requirement.

gross beta concentration of 2 E-10 uCi/mL in a sample of
an unknown isotopic content; or greater than 1.0 DAC in a
Page 44 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17
sample of a known isotopic content, the following actions
shall be taken:-
• The RSO will evaluate site conditions to determine
whether additional dust suppression methods or
respiratory protection is needed, and whether
posting for airborne radioactivity (UAC R313-15-
902) is required.
• The sample will be analyzed by gamma
spectrometry and, if necessary, by radiochemical
separation and laboratory analysis to determine the
activities of the radionuclides present.
• If it is confirmed or suspected that any employee
received or may have received 8 DAC-hours during
a single day, attempts shall be made to determine
the internal dose received using in vivo or in vitro
monitoring methods for the most significantly
exposed employee. The incident shall be
investigated and corrective actions taken to prevent
the event from reoccurring.
5.3.4.6 Care should be used to minimize errors in air sampling due
to:
• Excessive sample buildup resulting in loss of
material/ or activity self-absorption during counting.
• Excessive sample time which will effectively result
in a sample dilution due to sampling during low
exposure.
• Incorrect air volume determinations.
• Non-representative sampling area.
5.3.4.7 Air monitoring equipment shall be routinely calibrated and
maintained at intervals not to exceed six months.
5.3.5 Bioassay Sampling
5.3.5.1 All radiation workers at the site shall participate in a
bioassay program to assist in evaluating internal deposition
of radionuclides unless an exemption is authorized by the
RSO:
• A baseline bioassay shall be collected upon
employment and a termination bioassay shall be
collected when access to the restricted area will no
longer occur.
Page 45 of 67
EnergySolutions' Clive Facility CL-RS-PG-002
Radiation Protection Program Revision 17

program.
• Routine bioassay action levels shall be calculated
using the midpoint time of the sample frequency
unless actual time of intake can be determined.
• Bioassay results which exceed calculated action
levels shall be investigated in a timely manner. The
investigation should include an evaluation of work
activities and a more detailed analysis to estimate
the intake and resultant dose equivalent.
5.3.5.2 Bioassay samples shall also be used to determine dose to
personnel involved in an incident having a potential for a
significant intake of radionuclides as determined by the
Radiation Safety Officer.
5.3.5.3 Investigations should be coordinated and results reviewed
with responsible management prior to assigning dose to
person assessed with internal dose.
5.3.5.4 Management shall exercise due diligence to collect a
termination bioassay monitoring sample when a person
who participated in the bioassay program terminates
employment or concludes work involving the potential for
internal dose.
5.3.5.5 Special bioassay monitoring shall also be performed when
any of the following occurs:
• Nasal contamination is detected;
• Airborne monitoring indicates the potential for
intakes exceeding 500 mrem CEDE; or
