Dear Mr. Tauber:
SUBJECT:
REQUEST FOR INFORMATION CONCERNING EQUIPMENT QUALIFICATION FOR SEISMIC AND HYDRODYNAMIC LOADS FOR FERMI 2 In order to meet the operating license review schedule established for your facility, we request that you respond to the enclosed request for additional infonnation 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 Sunnary 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 Co.nplete Input RFI Visit to SER Fermi 2 5/8 6/8 - 6/12 6/26/81 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.

s Mr. Harry Tauber. MC c u 1981 Since we are conducting these reviews with the assistance of the national labs, we request that one copy of all responses to the enclosed request be ~ sent directly to:
Dr. Morris Reich Department of Nuclear Energy Building 129 Brookhaven National Laboratory Upton, New York 11973 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.
Sincerely, Yc %

p 414-1 414.0 Equipment Qualification Branch 414.1 In accordance with the requiremeits of GDC 2 and 4 all safety-related equipment is required to be des 1gned 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 designed to withstand appropriate combinations of the effects of normal and accident conditions with the effects of earth-quake loads.
The criteria to be used by the staff to determine the acceptability of your equipment qualification program for seismic ard dynamic loads are IEEE Std. 344-1975 as supplemented by Regulatory Guices 1.100 and 1.92, and Standard. Review Plan Sections 3.9.2 and 3.10.
State the extent to which the equi;rlent 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.
474.2 Provide a list of all safety-related systems together with a list of all safety-related equiement and support structures associated with each system. The equipment lists should indicate wnether the equip-ment is NSSS sunnlied or Rfl0 tunnlied. These lists should include all safety-related mechanical ecmponents, electrical, instrumentetion, and control equipment, including valve actuators and other appurtenances of active pumps and valves.
414.3 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 multt-axis.
c)
If by analysis, describe whether static or dynamic, single or multiple-axis analysis was 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 t
414-2 (4) location of equipment, i.e., building, elevation.
(5) Availability for inspection (Is the equipment already installed at the plant site?)
(6) A compilation of the raquired response spectra (or time history)
~
and corresponding damping for each seismic and dynamic load specified for the equipment together with all other loads considered in the qualification and the method of combining all loads.
-414.4 Identify all equipment that may be effected by vibratic'n fatigue cycla -
efft. cts and describe the methods and criteria used to qualify this equipment for such ic.ading conditions-414.5 Describe the results of any in plant tests, such as in situ impedance tests, and any plans for operational tests which will be used to confirm the qualification of any item of equipment.
414.6 To confirm the extent to which the safety-related equipment meets 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, SQRT will review the combined required response spectra (RRS) or the combined dynamic response, examine the equipment configuration and mounting, and then determine whether the test or analysis which nas been conducted demonstrates compliance with the RRS if the equipment was qualified by test, or the acceptable analytical criteria if qualified by analysis.
The staff requires that a " Qualification Sumary of Equipment" as shown on the attached pages be prepared for each selected piece of equipment and submitted to the 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.
