A.
BASES:
10 CFR Part 50, Appendix B, and 10 CFR Part 21.
B.
SCOPE: This inspection was performed primarily to review and gather seismic qualification data for safety-related parts and components supplied by General Electric, to review the method for similarity analysis, and to review the process whereby purchase orders for such items are fulfilled.
PLANT SITE APPLICABILITY: All nuclear power plants for which General Electric provides replacement parts and components.

OTHER FIN _ DINGS AND COMMENTS:
1.
Seismic Qualification Data The inspectors reviewed and obtained seismic qualification data on several components manufactured and/or supplied by General Electric for nuclear power plants including racks, local panels, transmitters, pumps, metal clad switchgear and relays.
The information could be useful in the staff's resolution of unresolved safety issue A-46.
The purpose for gathering the seismic qualification data is to review the adequacy of the method of seismically qualifying parts and components by similiarity analysis and to compare the seismic capa-bility of these items to the seismic requirements for particular nuclear plant sites. Only very preliminary assessments could be made during the inspection. More detailed analyses and evaluations will be performed later at the NRC staff offices. Therefore, no conclusions have as yet been drawn.
It was noted that General Electric by test and/or analysis has esta-blished a minimum seismic capability for components it supplies.
Preliminary assessment indicates that the method of qualification by similarity requires detailed justification. We have found, for instance, that relays and transmitters having the same nodel type but with different serial numbers or different casings exhibit different levels of seismic capability.

Guidelines for Supplying Qualified Components i
General Electric has established guidelines for completing purchase j
orders for components relative to seismic qualification requirements.
It was indicated that utilities generally do not specify the seismic requirements for components in their purchase orders.
l These guidelines include the following:
I I
For-safety-related components no longer available to the original design, General Electric reevaluates the replacement component to determine the effect of modifications on the seismic capability 1
relative to the original design. The inspectors reviewed records 4
of several similarity analyses.
For components that are safety-related and the purchase order l
does not specify seismic qualification requirements, General Electric supplies a product suninary sheet that identifies the seismic capability.
It is then the utility purchaser's respon-l sibility to assure proper use of the component.
For replacement of components that were originally provided by General Electric, General Electric can identify the component's seismic qualifications by locating the item on the Master Parts List (MPL) which in turn is-tied to design documents including seismic requirements. This information is provided to the purchaser.
For components not originally provided by General Electric (e.g., for a PWR-type NSSS), General Electric provides an equivalent component and specifies the seismic capability.
It is the utility's responsibility to assure proper application of the component.
NEBO-San Jose is the source for all General Electric products supplied to utilities with the exception of GE-Malvern which supplies safety-related relays and switches.
