Dear Mr. Scherer:
SUBJECT:
STAFF EVALUATION OF TOPICAL REPORT CENPD-252-P On December 15, 1977, Combustion Engineering submitted topical report CENPD-252-P, " Blowdown Analysis Method - Method for Analysis of Blowdown Induced Forces in a Reactor Vessel." The report was amended twice; Amendment 1-P was submitted on August 22, 1978 and Amendment 2-P was sub-mitted on October 20, 1978. We have completed our review of CENPD-252-P and our evaluation appears as the Enclosure to this letter.
Subject to the limitations discussed in the Enclosure, we conclude tnat the CEFLASH-4B computer code is an acceptable code for evaluating the subcooled decompression response of a pressurized water reactor primary coolant system following a postulated loss-of-coolant accident.
It is requested that CENPD-252-P be resubmitted as an approved report.
The copies of the approved report should include this approval letter and the responses to our requests for information. However, the computer printouts provided in the responses need not be included in the approved report.
Should NRC criteria or regulations change such that our conclusions con-cerning CENPD-252-P are invalidated, you will be notified and given an opportunity to revise and resubmit your topical report should you so desi re.
When CENPD-252-P is referenced in a license application, the non-proprietary version should also be referenced. We do not intend to repeat our review of this report when it appears as a reference in a particular license application.
Sincerely,
@'.'[ h y Robert L. Baer, Chief Light Water Reactors Branch No. 2 Division of Project Management
