SUBJECT:
SUtlMARY OF tlEETING ON ENVIRONf1ENTAL QUALIFICATION OF EQUIPMENT A meeting was held on March 25, 1982 in Bethesda, flaryland, at the applicant's
The staff met with representatives of the applicant, the A/E (Bechtel) and the NSSS vendor (Combustion Engineering).
The meeting attendees are listed in Enclosure 1.
Background information and summary of the meeting are presented below.
Background
The staff review of the environmental qualification program for Palo Verde equipment within the NSSS (CESSAR) scope consists of two parts.
First as part of the CESSAR application, the staff is reviewing the methodology for the HSSS program scope which is described in Combustion Engineering Topical Report CENP0-255, Revision 3.
The staff will then audit the environmental qualification results, obtained by using the CENPD-255 program methodology, for specific items of equipment as part of the Palo Verde application.,
The staff review of the program for the BOP scope (both the methodology and auditing of the results) is all being performed as pat t of the Palo Verde application.

The staff's audit of the results of the total program (both NSSS and BOP) will be conducted at the site where the records are kept.
In prepar tion for this audit, the staff has requested the Palo Verde applicant (as well as appl.icants for other plants) to submit a report which addresses how the equipmel1t qual)fica-tion conforms to the staff requirements contained in NUREG-0588.
,i s The staff informed the app'licant that it had met with representatives of,Co bus-tion Engineering on March 19, 1982 to discuss the methodology for the eq0ip ent qualification program within the CESSAR scope.
As a result of that meeting, )the staff accepted the philosophy of thermal equivalence, provided that each test report (ln support of plant specific applications, such as Palo Verde) addresses the restrictions presented in Enclosure 2.
The staff also accepted the philoso)Ihy of time margins less than an hour and mill infors Combustion Engineering of

APPL CATION OF "THERMAL EQUIVALENCE" TEMPERATURE QUALIFICATION
.The general method of temperature qualification by "thermal equivalence" is acceptable with the understanding that the containment temperature transients will be reviewed on a plant-specific basis and CE will provide a detailed ddscription of the analytical modelling techniques and application of the thermal equivalence
- approach, including the basis for selecting test para-meters.
The following restrictions shall be incorporated as part of the.
general application of the methodology.and conformance shall be documented in each test report:
l.'pplication of the thermal equivalence app'roach shall be justified on each 'piece of equipment, including any judgements regarding the survivability limits of the equipment.
2.
Describe the specific heat transfer modelling and justify that the critical surface or surfaces are limiting both in'time and'ocation.
3.
Multiple temperature measurements of the critical surface from testing shall envelope the calculated critical surface(s) temperiture transient, including the initial temperature ramp.
"Soaking" will not be permitted.
)
0 y P
I The margin between the minimum measured surface temperature and the calculated surface temperature shall exceed the uncertainties associated with design, production, testing, and operability time, or a temperature margin of 15 degrees by reference to the guideline of IEEE-323 with an appropriate margin for operability 'time.
Application of.the thermal-equivalence. approach. shall be. limited-to the limiting superheated steam harsh environment.
The limiting environ-ment and operability time shall consider a spectrum of breaks.
