Acceptance Review Review Status:
Complete Radiation Protection Section has reviewed chapter 12 of the subject SAR, and related information in chapter 9 and chapter 3.
We find the material submitted to be insufficient for us to continue our review. _Less than half of the required information is included. We have attached a list of information which will be needed before ve can develop our first round of questions when the application is docketed. The needed information was first identified to the applicant in his previous submission of B-SAR-- -
by our draft round one question of September 13, 1974, which were transmitted to the applicant by Mr. Schwencer's letter of October 4,1975. The attached set of requests for information is an elaboration of the earlier statement and consistent with Regulatory guide 1.70.3 (Rev.1), which has now been replaced by Reg. Guide 1.70 (Rev. 2).
This review was performed by William E. Kreger, Leader, Radiation Protection Section.

(331.0 RADIOLOGICAL ASSESSMENT BRANCH 331.1 Describe your position on Regulatory Guide 8.8, which has guidance (Section 3.2) on system design features that relate to maintaining occupational radiation expenses as low as practicable (ALAP).
1 331.2 Describe any design features of the fuel handling system that relate (Section 9.1.4) to maintaining occupational radiation exposure ALAP during refueling, including spent fuel transfer.
This includes features that may reduce the radiation fields where personnel have to be, that reduce the time needed for refueling or equipment maintenance operations in significant radiation fields, and that reduce possibility for and magnitude of contamination of the equipment due to f ailed fuel leakage or flaking off of crud during spent fuel element transfer.
331.3 Describe any consideration that may have been giving to reducing (Section 9.3.4) reactor coolant system concentrations of fission products and activation products in determining letdown flow rates. Reduced concentrations are related to maintaining occupational radiation exposure ALAP.
331.4 Describe the management policy related to ensuring that the Babcock I
12.1.1) 205 System is designed to ensure that occupational radiation exposures
(' (Section for activities on and around the system will be ALAP.
331.5 Describe system and equipment design consideration that are directed (Section 12.1.2) toward ensuring that occupational radiation exposures are ALAP.
Describe how experience from past designs end from operating plants is utilized to develop improved design for ensuring that occupational radiation exposures are ALAP. t.ny design guidance (both general and specific) given to the individual system or equipment designers ehculd be included. Describe how the design is directed toward reducing the need for maintenance of equipment and to reducing radiation levels and time spent where maintenance and other operational activities are required. Any mechanisms that provide for design review by a competent professional in radiation protection should be described.
Also describe any mechanism for incorporating operating experience in design improvements.
These descriptions l
should be detailed in the PSAR, including an indication of whether, and if so how, the design consideration guidance provided in Regulatory Guide 8.8 will be followed; if it will not be followed, describe the specific alternative approaches to be used.
331.6 Describe sources of airborne radioactivity resulting from reactor (12. 2. 2) vessel head removal, relief value venting and movement of spent fuel. The description should include a tabulation of the calculated quantities of radioactivity expected to be released by nuclides.
The models and parameters used for calculating airborne radioactivity quantities should be provided.
331.7 Describe equipment and system design features used for ensuring (12.3.1) that occupational radiation exposures are ALAP.
Indicate whether,

J x
Guide 8.8 has been followed; if not followed, describe the specific alternativc approaches used.
Provide illustrative examples of such system and equipment design l.
features. The description should include those features that reduce need for maintenance and other operations in radiation fields, reduce l
radiation sources where operations must be performed, allow quick
}-
entry and easy access, provide remote operation capability or reduce the time required for work in radiation fields and any other features i
that reduce radiation exposure of personnel.
It should include descriptions of methods for reducing the production, distribution, and retention of activation products through design methods, j
material selection, water chemistry, filtering, decontamination procedures, etc.
An illustrative example should be provided for I
each of the following components (including equipment and piping layouts) :
the reactor, liquid filters, demineralizers, particulate filters, pumps, steam generators, valve operating stations, and sampling stations.
