APR 15 HEMORANDtM FOR:

H. L. Thompson, JrS, Acting DirectorDidsfon of Huan Factors Safety FROM:

~.Jt. Mazetis, -Chairman, Robinson PTS Task Force

SUBJECT:

ROBINSON 2 SHORT TERM TASK FORCE ON PRESSURIZED THERMAL SHOCK (PTS)

Your-memorandum dated March

,-1982 appointed a Task Force to ake a detailed review and prepare. a-report-on_ the status of; efforts: on PTS-at the R. B.. Robinson Nuclear Plant. A site visit was arranged on April 5-7th, during which time audits were conducted on procedures and training, specifically with regard to PTS.

The Task Force members consisted of the following individuals:

Gerald R. Mazetis - DSI/RSB - Chairman H. Brent Clayton -

DHFS/PTRB Joseph J. Buzy - DHFS/LQB Edward Throm,-

DS..RSB Raymond Klecker -

DE/MTEB Roy Woods - DST/GIB -(ex-offic.o)

Our instructions were to provide a report in 30 days (April 15, 1982) character izing the problem(s), methodology of resolution, bases for conclusions, and recom mehdations-regarding the adequacy of. in-place training programs. and opefating pro cedures.

In addition, you requested that the report attemipt to characterize the applicability of this effort to. other like facilities and propose review schedules and triteria that can be used in reviewing. the. other facilities of. special. concern.

The enclosed evaluation provides the requested report..- The site audit of training programs was conducted by Joseph J.- Buzy.

The site audit of procedures was con ducted primarily by H. Brent Clayton.

The. evaluation of the overcooling-history at Robinson 2 was performed by Edward Thra... Ray, Kecker. and Neil -Randall although not part of the on-site audits, contributed to the fracture mechanics assessment.

Roy Woods, although also not part of the site visit, assisted with the report to ensure consistency with other ongoing PTS programs.

As indicated in Section 3.0, "Key Findings from the Robinson Audit,' It is clear that the control room emergency procedures remain weighted toward-core cooling and do not go far enough in addressing the PTS issue.

Pending generic resolution, of TmI Action Plan Item I.C.1, such a procedural shortcoming could have been tempered during our. audit of plant personnel by a strong awareness and knowledge of the PTS issue; however, the audit produced a varied response from good to poor..

The reason for the varied response is due in large part to the need for closer validation by CPSL of operator retention of the material covered in the classroom training sessions on PTS.

A more complete'discussion of the intepviews Is presented In Section 3.3, and our omendations are addressed in Section 5.0.
