OMB CLEARANCE REQUEST Proposed Survey on Schedule for Review of Topical Reports on RETRAN Methodology and Associated Reloads RETRAN is a computer code approach for analyzing the thermal-hydraulic response of Nuclear Steam Supply Systems to hypothetical Loss of Coolant Accidents and Operational Transients.
It is the NRC staff's understanding that utilities intend to submit topical reports describing their methodology for transient analysis using this computer code.
These methods would then be applied to support future reloads when necessary. What the NRC staff needs to know is (A) which utilities will be submitting these topical reports in 1982 and 1983, (B) when do these utilities require completion of NRC staff analysis, and (C) will these utilities use RETRAN to support a reload application in 1982 or 1983? The NRC staff needs to know this information so that (1) it can perform its duties in an efficient and effective manner and (2) utility schedules for implementation of this computer code to support reload applications will not be unnecessarily extended out in time awaiting the completion of the NRC review.
The RETRAN computer code is applicable to light-water reactor (LWR) systems.
The code would be utilized to support nuclear fuel reloads. The code and reloads would come under the following paragraphs of 10 CFR, Part 50:
(1) 50.46 Acceptance criteria for emergency core cooling systems for and LWRs and ECCS Evaluation Models. RETRAN could be used to Appendix demonstrate to the staff that the licensee meets 50.46 and K
Appendix K, II.l.a.
(2) 50.59 Changes, Tests, and Experiments.
Some fuel reloads require changes to the utility's license.
RETRAN could be used to support a reload license application.
Therefore, this information comes under Part 50 and is being primarily requested to assess the industry's use of this code to meet 10 CFR 50, paragraph 50.46 and Appendix K,.II.l.a.
In order to obtain this information, each project manager (about 50 total) will conduct a telephone survey asking each nuclear utility (about 50 total) questions A through C above. The telephone inquiry should require less than 30 minutes on the part of the project manager and the utility.
The information would be used by the NRC staff in organizing and allocating NRC resources to complete the review of these topical reports in an efficient, effective, and timely manner. Total cost to NRC is estimated to be about 25 persor.-hours; total cost to utilities is estimated to be about 25 person-hours.
In each case, this was determined by multiplying 50 persons times one half hour.
OMB clearance is requested as an add on to the NRC present Part 50 clearance.
