NUREG-1537, Part 2 - NRC

CHAPTER
include any dilution that occurs before or at the point of release to the
unrestricted environment.
Estimates should be given of solid radioactive waste curie content and
volume. The methods used to process solid waste should be briefly
discussed.
Review Procedures
The reviewer should determine that all sources of radiation in the facility are
adequately discussed and that the specific topics discussed in the standard format
and content guide are complete and sufficiently described. Some of this
information may be verified during site visits associated with the licensing process,
and some may be assessed by comparison with similar operating facilities that NRC
has found acceptable.
If the applicant describes processes involving radioactive material, the reviewer
should compare the description of the types of radioactive materials present with
the applicable process description, including radionuclide inventories and mass
balances and chemical and physical forms, to verify that all radioactive materials
associated with the process have been identified.
For a licensed reactor that is in operation, material balance inventory forms
(NRC/DOE Forms 741 and 742) can be reviewed to verify quantities and general
locations of special nuclear material (SNW).
The reviewer should examine the description and discussion of all sources of
radiation to verify that they are described in sufficient detail to provide the bases
for the design and assessment of personnel protective measures and dose
commitments. The reviewer should evaluate the models used to predict airborne
and liquid radionuclide concentrations and the physical and chemical forms of the
radionuclide inventories to verify that they are appropriate fbr the facility and
process conditions. If radionuclide data (inhalation or ingestion exposure data or
concentration and inventory data) are available for the applicant or for facilities
with similar processes and configurations, the reviewer should compare the
predicted liquid and airborne radionuclide concentration distributions and possible
doses with measured exposure data to validate the conservatism of the best
estimates of the radionuclide concentrations. To evaluate consistency, the
reviewer should use the applicant's summary of the calculated doses resulting from
radionuclides predicted or detected during normal operations in areas that could be
occupied by facility staff and the public.
The reviewer should confirm that all solid sources of radiation at the facility are
described and discussed in sufficient detail to permit evaluation of all significant
