Dear Mr. Tallman:
Subject:
Request for Additional Information (Ecuipment Qualification Branch)
Enclosed are requests for additional infonnation from the NRC Equipment Qualification Branch (EQB, 271.1-11).
After reviewing the enclosed requests, your representatives should contact the Seabrook Project Manager (Mr. L. L. Wheeler, 301/492-7792) to coordinate a date for your responses to be received by the NRC.
Sincerely.

SEABROOK FSAR QUESTICN LIST FOR SECTIONS 3.9.3.2 AND 3.10, SEISMIC AND DYNAMIC QUALIFICATION OF MECHANICAL AND ELECTRICAL EQUIPMENT Section~3.9.3.2 271.1 The FSAR shodld clearly define loads and how they are being combined.
The loads should be defined such that they can be distinguished from one another as to their causes, for example, normal operation,. loss of coolant accident, high energy line break, etc.
In tables 3.9(B) 2 both the load definition and the load combination should be clari fied.
271.2 for operabftity qualification, thermal loads should be considered as a primary load and both the inertia and relative displacement load from earthquake and other dynamic loads should be accounted for.
271.3 Clearly def[ne the stress limits for non-ASME components and address interaction effect of stress components in a complex stress field, for example between tension and shear.
271.4 Do you intend to commit to the most recent IEEE Standards, that is, IEEE-323-1974 and IEE-344-1975 and Regulatory Guides 1.89 and 1.100 for both BOP and NSSS equipment? The commitment should be reflected in the FSAR or, the justification for not committing.
271.5 Please provide submittal dates for the following documentation:
1.
Report number of the Westinghouse Seismic Qualification Report on the motors for the emergency feedwater pumps.
it.
The motor analysis for the diesel fuel oil transfer pump.
271.6 What active pumps and active valves. remain to be qualified by test and/or analysis as referenced ip FSAR Sections 3.9(B).3.2?
Regarding,pbnp and valve operability assurance, was the entire assembly
.271.7 (pump and ' motor or valve and driver) analyzed and/*e tested as a unit or separately.
If separately did the analysis include the load:
imposed from each component on one another.
271.8 In orde~r to assure operability through the qualif.ied life of the equipment it.is nece.ssary, first to age the equipment to a condition i
which simulates its expected end of life' condition including the effect of radiation, and second, to qualify for the accident environment.
Discuss your qual-ification program in sufficient detail addressing the qualification sequence indicated above.

- Section 3.10 271.9 It is indicated that electric equipment that do not undergo a change of state are qualified for seismic resistance by analysis. Batteries g
have heavy mas,s and the terminals connecting the batteries generally e in rigidity. Thus, the batteries may develop an interface for chang'with supporting analysis.
need to be qualified by tests Also,-certain cooling accessories to transformers may need to be qualified by a combination of test and analysis. Modify the FSAR to clearly indicate the procedure you are following.
-271.10 Certain electric equipment may belub' ject to the effect of impulsive pressure puTfis or other dynamic loads.
These equipment may be close to a high energy line.
- Describe in the FSAR what other dynamic loads will be used in the qualification of electric equipment, and how the dynamic loads-will be combined with the seismic loads when (1) the qualification is performed by analysis, (2) the qualification is done by tests.
l 721.11 Indicate in the FSAR how the seismic qualification will be performed
.in sequence with environmental qualification test as required under IEEE-323-1974.
