e 1.0 GRAND GULF HPCS SEISMIC QUALIFICATION Table 1 below lists the items and qualification methods used on the Grand Gulf HPCS System. Each one is discussed separately in 4 this report. TABLE 1. Grand Gulf HPCS System MPL NUMBER , ITEM SUALIFICATION METHODS E22-5001 HPCS Diesel Engine - Analysis and Test Generator E22-S002 Motor Control Center Test E22-5003 HPCS Transformer Test E22-S004 HPCS Switchgear Test 1.1 E22-S001, HPCS Diesel Engine - Generator The Diesel Engine - Generator qualification is based on stress analyses and seismic testing performed by the vendor. Table 2 shows a summary of the critical items that are fastened or el-ectrically connected to the engine - generator. Items 1 through 17 are qualified by. stress analysis with positive' margins of safety and-resonant frequencies greater than 33 hertz. The ana-lyses are contained in References 1,2,3 & 7 . Item'18, the Mechanical Overspeed Trip, is seismically qualified by an opera-bility verification. The analysis is contained in Reference 4. The Battery and Rack, item 19, was tested to 1.5g biaxial at resonance. Reference 5 contains the test report. Item 20, the Engine - Generator Starting and Control System is qualified by similarity to a tested Cofrentes unit. The vendor still needs to certify the seismic capability of a modified reactor bracket. The test report of the Cofrentes unit is contained in reference 6. 1.2 E22-S002, Motor control Center The Motor Control Center is qualified to SQRT criteria. The forms are in the attached Appendix 1. 1

NOTE 1: The unit at Grand Gulf has all the seismic bracing as required after seismic testing. However, per paragraph 6.3.1 of refer-enced seismic report, tray SA required adding a screw through the side af ter test 57 to prevent contact chatter. The manu-facturer claims that there is no other docementation to sup-port the addition of this screw. It is his opinion that the technical reviewers of the test aecided that it was not neces-sary. The test ZPA's in this case was 2.8g horizontal and ' 4.0g vertical.

i This relay is qualified by comparing the current seismic capability with the maximum expected acceleration. The seismic capability is from GE PSMBD Engineering Section Memo 08609. The maximum expected acceleration is obtained by multiplying the trans-missibility at the mounting location times the ZPA for t'his elevation. All other essential devices in the Grand Gulf Switchgear are simila'r to those on tlie tested unit. .

SUMMARY
(COMTI!1UED) EQUIPME!1T NO. See Attached __
- 4. Functional Requirements Switches..'are active and are r'equired to remain operable during and after a seismic event.
.~
I
- 5. Demonstration Capability Specimens were subjected to seismic load's greater than required for Grand Gulf installation. Specimens functioned properly throughout testing and showed no signs of damage or deterioration.
~
- 6. Rationale for Qualification certification I (Includ'e Decision analysis with comparison to acceptance criteria, l approach for demonstrating operability, and consideration of l high-frequency response.)
The switches are located in panel H13-P601 which was tested l seismically to envelop the Grand Gulf RRS. The TRS enveloped the RRS by a large margin resulting in measured accelerations at the panel device locations being excessive. The panel TRS and responses were ratioed down such that the adjusted TRS enveloped the RRS by a factor of two. The resulting adjusted device accelerations are enveloped by the switch test data, indicating the switches satisfactorily meet the Grand Gulf requirements with margin. l
