Dear Mr. Aswell:
- b'5 SUBo'ECT:
REQUEST FOR D! FORMATION CONCERNING EQUIPtlENT QUALIFICATION FOR SEIS41C AND HYDRODYNAi4IC LOADS FOR WATERFORD In order to meet the operating license review schedule established for your facility, we request that you respond to the enclosed request for additional information as soon as possible.
The Seismic Qualification Review Team's (SQRT) tentative schedule shown below is based upon receipt of your complete and thorough response to the enclosed request one month before the planned site visit.
In accordance with the procedure described under item 6 of the enclosure, we plan to select the equipment to be reviewed within one week of receipt of the applicants submittal.
The schedule would then require you to provide the " Qualification Sumary of Equipment" for the selected equipment within one week (or two weeks before the site visit).
Tentative Review Schedule Applicant SQRT Response to Si te Complete Input RFI Visit to SER Waterford 4/3 5/4 - 5/8 5/22/81 We request that you advise us as soon as possible if you can support this schedule since a change will impact our schedules for other plants.

Mr. D. L. Aswell..,
193 I Since we are conducting these reviews with the assistance of the natfonal labs, we request that one copy of all responses to the endosed request be sent directly to:
Mr. Richard Rahl EG&G Idaho, Inc.
P. O. Box 1625 Idaho Falls, Idaho 83401 If we are to meet the above schedule it is essential that the labs receive your submittals at the same time as the NRC staff.
Si ncerely, Tkhc i.t.

Equipment Qualification Branch Seismic Qualification Review Team Request for Additional Information
~
270.1 In accordance with the requirements of GOC 2 and 4 all safety-related equipment is required to be designed to withstand the effects of earth-quakes and dynamic loads from normal operation, maintenance, testing and postulated accident conditions.
GDC 2 further requires that such equipment be desigt.?d i.0 withstand appropriate combinations of the effects of normal ard accident conditions with the effects of eartn-quake loads.
The criteria to be used by the staff to determine the acceptability of your equipment qualification program for seismic and dynamic loads are IEEE Std. 344-1975 as supplemented by Regulatory Guides 1.100 and 1.92, and Standard Review Plan Sections 3.9.2 and 3.10.
State the extent to which the equicment in your plant meets these requirements and the above requirements to combine seismic and dynamic loads.
For equipment that does not meet these requirements provide justification for the use of other criteria.
270.2 Provide a list' of all safety-related systems together with a list of all safety-related eouioment and support structures associated with each system. The equipment lists should indicate wnether the equip-ment is NSSS cunnlied or RI)0 sunnlied. These litts should include all safety-related mechanical ccmponents, electrical, instrumentetion, and control equipment, including valve actuators and other appurtenances of active pumps and valves.
270.3 For each safety-related equipment item, the following information should be provided:
(1) Method of qualification used:
a) Analysis or test (indicate the company that prepared the report, the reference report number and 'date of the publi-cation).
b)
If by test, describe whether it was a single or multi-frequency test and whether input was single axts or multi-axis.
c) If by analysis, describt.hether static or dynamic, single or multiple-axis analysi' used.
.d) provide natural frequency (or frequencies) of equipment.
(2) Indicate whether the equipment has met the qualification requirements.
~
(3)
Indicate whether the equipment is required for:
a) hot stand-by b) cold shutdown c) both d) neither y-j i-
2
-(4) location of equipment, f.e., building, elevation.
(5) Availability for inspection (Is the equipment already installed at the plant site?)
(5)
A compilation of tne raquired resconse spectre (or time nis;ory) and corresponding damping for eacn seismic and dynamic load specified for the equipcent together with all other Icacs considered in the qualification and the method of cc:oining all loads.
270.4 Identify all equipnent that m.sy be effected by vibratien fatigue cycla -
effects and describe the methods and criteria used to qualify nis equipment for such leading conditions 270.5 Describe the results of any in plant tests, sucn as in situ i=;edance tests, and any plans for operational tests which will be used to ccnfirm the qualification of any item of equipment.
270.6 To confirm the extent to whicn the safety-related equipment reets the requirements of General Design Criterion 2 and 4, the Seismic Qualifi-cation Review Team (SQRT) will conduct a plant site review.
For selected equipment. SQRi will review the c0mbined required response scectra (RRS) or the combined dynamic response, examine the equipment configuration anc mounting, and then determine whether the test or analysis which nas oeen conducted demonstrates compliance with :ne RRS if the equipeent was qualifiec by test, or the acceptable analytical criteria if qualified oy analysis.
The staf f requires that'a " Qualification Summary of Equipment
- as snown :n the attached pages be prepared for each selected piece of equipment and submitted to t.1e staff two weeks prior to the plant site visit.
The applicant should make available at the plant site for SQRT review all the pertinent documents'and reports of the qualification for the selected equipment.
After the visit,-the applicant should be prepared to submit certain selected documents and reports for further staff review.
