!Plower 1Compm1111y General Offices: 212 West Michigan Avenue, Jackson, Ml 49201 * (517) 788-0550 August 3, 198i Director, Nuclear Reactor Regulation Att Mr Dennis M Crutchfield, Chief Operating Reactors Branch No 5 US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLANT - SEP TOPIC III-6, SEIS.MIC DESIGN CONSIDERATIONS By letter dated January 19, 1981, the NRC provided a report, NUREG/CR-1833, concerning the ~eismic evaluation of the Palisades Plant. Encloslire 2 to this letter and Table 6-1 of the report identified several items for which the staff had insufficient information to complete its review, and requested that CPCo develop and provide that information to the NRC. This letter transmits a portion of that information.

Attachment 1 provides Combustion Engineering Report TR-ESE-437, "Palisades CRDM Dynamic Analysis Report", dated July 6, 1981. Attachment 2 provides a report entitled "Seismic Design Evaluation of the Palisades Nuclear Power Plant Unit 1 Main Components" dated July, 1981. This report substantiates the seismic design adequacy of the steam generators, reactor coolant pumps and the reactor vessel and its supports. Attachment 3 provides a summary listing of stress margins calculated for the reactor internals.

In all cases, these reports confirm the seismic design adequacy .of Palisades' components. Submission of these reports completes our actions for open items 6, 7, 8 and 9 of enclosure 2 to your letter of January 19, 1981.
