Subject:
Request for Additional Information for the Review of the Wolf 4 ek t*
Plant, Unit 1 Regarding Seismic and Dynamic Qualification of
/
Equipment As a result of our continuing review of the Wolf Creek Plant, Unit 1 FSAR, he find that we need additional information to complete our evaluation. The specific information required is in the area of seismic and dynamic qualification of equipment and is presented in the Enclosure.
To maintain our licensing review schedule for the Wolf Creek Plant FSAR, we will need responses to the enclosed request by January 7,1982. The Seismic Qualification Rdview Team's (SQRT) scheduled site visit to Wolf Creek Unit 1 from 2/09/82 to 2/12/82 is based upon receipt of your complete and thorough response to the attached request one month before the planned visit.
In accordance with the procedure described under Q271.2WC of the: enclosure, we plan to select the eq0ipment to be reviewed within one week of receipt of your submittal. The schedule would then require you to provide the "Qualiff-cation Summary of Equipment" for the selected equipment within one week (or two weeks before th6 site visit).
If you cannot meet this date, please inform us within seven days after receipt of this letter of the date you plan to submit your responses so that we may review our schedule for any necessary changes.
Please contact Dr. G. E. Edison, Wolf Creek Licensing Project Manager, if you desire any discussion or clarification of the enclosed request.
Sincerely.

' EQUIPMENT QUALIFICATION BRANCH 271.1WC-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 designed to withstand appropriate combinations of the
(
effects of-normal and accident conditions with the effects of earthquake loads.
The criteria to be used by the staff to determine the acceptability of your equipment qualification program for seismic and dynamic loads are i.
IEEE Std. 344-1975 as supplemented b3 Regulatory Guides 1.100 and 1.92, and Standard Review Plan Sections 3.9.2, 3.9.3 and 3.10.
State the extent to which the equipment in your-plant meets these requirements and the above requirements to combine seismic and dynamic loads.
For equipment that does not meet these requirements justification will be 1
needed for the use of other criteria.
271.2WC To confirm the extent to which the equipment important to safety meets the. requirements of General Design Criterion 2 and 4, the Seismic Quali-f-
fication 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 conf'guration and mounting, and then determine whether the test or analysis which has been conducted demonstrates compliance with the RRS if the equipment was quali-fied by test, or the acceptable analytical criteria if qualified by analysis, 271.3WC-In order to select equipment types for a detailed review it is necessary to obtain a list of all equipment important to safety.
Equipment should be
' divided first by system then by component type. Attachment #1 shows a tabular format which should be followed to present the status summary of seismic and dynamic qualification of all equipment important to safety.
Attachment #2 shoss suggested categories of component type to be listed 3.
in Attachment #1.
Provide a complete set of floor response spectra identifying their applicability to the equipment listed in Attachment #1, After the information on Attachment #1 is received, a selection will be made of the equipment to be reviewed'by the site audit. Specilfic infor-mation on equipment selected for audit should be presented as shown on Attachment #3 which should be provided to the NRC.' 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,-
i applicant should be prepared to submit certain selected documents -
_ and reports for further staff review.
The purpose of the site audit 15 to confirm the acceptability of the seOmic and-dynamic qualification of all equipment important to safety based on the revf ew of a few selected
- pieces.
If a number of '
4 i.
5
+
2-deficiencies are observed or significant generic concerns arise, the deficiencies should be removed for all equipment important to safety subject to confirmation by a follow-up audit of randomly selected items before the fuel loading date.
