MEMORANDUM FOR:

SUBJECT:

TI A 82-53 EQUIPMENT QUALIFICATION REQUIREMENTS FOR NUREG-0737 ITEMS References :

1) Memo fm. R. Spessard (Reg. III) to D. Eisenhut,

" Equipment Qualification Requirements for NUREG-0737 Items II.F.1.a and II.F.2 for Davis-Besse Nuclear Power Station", August 31, 1982

2) Letter fm. D. Eisenhut to All Operating Nuclear Power Plants, " Followup Actions Resulting from the NRC Staff Recommendations Regarding the Three Mile Island Unit 2 Accident", September 13, 1979
3) Letter fm. H. Denton to All Operating Nuclear Power Plants " Discussion of Lessons Learned Short Term Requirements", October 30, 1979
4) NUREG-0737 Clarification of TMI Action Plan Requirements

_i Reference 1) indicated that certain NUREG-0737 required instrumentation installed at Davis-Besse does not meet seismic and environmental qualification requirements of Appendix B criteria of NUREG-0737. Since the June 20, 1982 rule suspending the Technical Specification deadline for environmental qualifications does not apply to seismic qualifications and since no other relief has been given for seismic qualification requirements, NRP, was requested for a position regarding the " operable" status of certain equipment which is not seismically qualified.

At the present time, only the subcooling meter is covered by Technical Speci-fi ca tions. There is no basis, however, for declaring this instrument "in-

)

operable" for lack of seismic qualification since no Commission regulation or q

Confirmatory Order requires such qualificaticn.

The remaining instrumentation l

is also not covered by regulation or Confirmatory Order nor is it yet required to be operable by Technical Specifications.

We have reviewed existing documentation (References 2, 3 and 4) which provided guidance and identified requirements' to the licensees for the instrumentation of concern. When covered by future Confimatory Order or regulation, the following qualification requirements would apply:

Item Envi ronmental Seismic Qualification Qualification Noble: Gas ibnitors Yes Ho (II.F.1.1)

Particulate Monitors No No (II.F.1.2)

Containment Sump Level Yes No Narrow Range (II.F.1.5).

Subcoolin Meter Yes Yes (II.F.2 a,s

C. E. Norelius, Director, Division of Engineering and g Technical Programs, Region III E/5 M*d i FROM:

Darrell G. Eisenhut, Director, Division of Licensing, Gn7ld puj; NRR

SUBJECT:

TIA 82-37. TESTING OF NORMALLY CLOSED CHECK VALVES Task Interface Agreement 82-37 requested NRR assistance regarding testing requirements for normally closed check valves. The TIA Action Plan identified four items which we believe, are addressed by the following listing of those test methods which are acceptable for any check valve in which the full stroke motion of the disc cannot be directly observed or where there is no position-indicating device.

These four methods.are currently being accepted in IST program reviews.

By demonstrating that the valve can pass the full flow which has a.

been taken credit for in FSAR analyses.

V.

b.

By showing that, for the measured flow, the pressure loss through k

the valve is such that the valve could only be fully open.

By using a mechanical exerciser which can be observed to move 3

c.

g through a full stroke.

d.

By partial disassembly of the valve and manually moving the disc l

through a full stroke.

We believe these stroking tests assure that the valve is exercised at least to the position required to fulfill its function and, therefore, the intent of ASME Section XI requirements are met.

This completes our planned activities on TIA 82-37.

v i

ACTION PLAN: Region I!! requests NRR technical assistanc,e concerning test requirements for nomally closed check valves, as;follows:

1..Specify what constitutes an acceptable.ISI test: fo$ swing or tilting disc check valves not equipped with a mechanical exercisor. Mat)

I

2. ' Detemine if the observation of " flow throughithe heck valve" was acceptable to satisfy 10 CFR 50.55a requirements for IST testing at Davis Besse. (ME) i 3.

Specify if the use of differential pressure measurynents across individual check valves.is an acceptable means for satisfying IST; requirements. (MR) i 4

Specify whether or not licensees should be allowed [(as an alternative to the test method and acceptance criterion described in the ASME Code) to: demonstrate that under design conditions, the valves will pemit desigr. flows and are therefore ment, appropriate baseline differential presseres Jstablish, by test and measur capable of performing their intended. function'or; at reference flows which can be used in place of r.onexistent preoperational test' pta. tMB)
