NUREG-1537, Part 2 - NRC

RADIAnON PRoTEcnoN PROGRAM AND WASTE MANAGEmEr
* The applicant should present the best estimates of the maximum annual
dose and the collective doses for major radiological activities during the full
range of normal operations for facility staff and members of the public.
The doses shall be shown to be within the applicable limits of 10 CFR
Part 20.
* Airborne radioactive material sources should be described in sufficient
detail to provide the bases for the design and assessment of structures,
systems, and components, and of personnel protective measures and dose
commitments. -
* Conservative best estimates of the predicted concentrations, locations, and
quantities of airborne radionuclides during the full range of normal
operation in areas occupied by personnel should be discussed.
* Conservative best estimates of the predicted locations and magnitude of
external radiation fields during the full range of normal operation in areas
occupied by or accessible to personnel should be discussed.
* The applicant should identify models and assumptions that are used for
predicting and calculating the dose rates and accumulative doses from such
radionuclides as &rgonAl (Ar-41), nitrogen-16 (N-16), and vapors,
aerosols, and airborne radioactive particulates in both restricted, controlled
(if present), and unrestricted areas. The applicant should identify
(1) locations of specific sources (e.g., coolant water, beam tubes, and gasor
air-driven rabbit systems), (2) expected production rates, release rates,
and concentration distributions in occupied areas and resultant personnel
doses or dose rates, and (3) release points from the control of the reactor -
facility, dilution air (quantities and sources), quantities and concentrations
expected to be released, dispersion and diffusion, concentration at point of
interest, applicable average atmospheric conditions, plume spread,expected
concentration distnibutions in unrestricted areas, and applicable
radiation dose rates, including gamma-ray shine from elevated plumes and
inhaled or ingested dose commitments. The analysis should contain
conservative best estimates of the predicted annual total doses to at least
the following in the unrestricted areas: (1) the ma=im exposed
;indiidual, (2) the nearest permanent residence, and (3) any location of
special interest, such as a classroom or campus dormitory. The discussion
and calculations should show that the sums of internal and external doses
to thefacility. staffand the public are within the limits of IO CFR Part20 -
and that ALARA principles are applied. -
* Liquid effluent volumes and radionuclide concentrations should be shown
to be within the requirements of 10 CFR Part 20. The discussion should
