Three Mile Island Nuclear Station, Unit 1, (TMI-1)
Operating License No. DPR-50 Docket No. 50-289 Seismic Adequacy of Control Room Panels and Instruments (R.G. 1.97)
On January 5,1987, GPUN discussed by phone with J. Thoma (NRC) the seismic evaluation of the control room panels and instruments at TMI-l required by R.G. 1.97.
By letters dated October 1, 1984 (5211-84-2252) and June 5,1986 (5211-86-2097) GPUN committed to verifying the seismic adequacy of the subject panels and instruments by the end of the Cycle 7 refueling (currently scheduled for fall 1988).
With the resolution of the USI A-46 issue via Generic Letter 87-02 dated February 19, 1987, GPUN intends to use the methodology of Generic Letter 87-02 based on experience data to demonstrate seismic qualification of the control room panels, including ir.struments mounted on the panels.
This is n exception to the guidelines of R.G.1.97 which specify that the seismic portion of qualification should be in accordance with R.G.1.100 and IEEE-344 '975.
Based on our understanding of the January 5,1987 phone r versation, please be advised GPUN will complete the Control Room (R.G.1.97) panel and instrument seismic qualification by the end of the Cycle 7 refueling outage.
GPUN requests notification within 30 days of the date of this letter if this approach is unacceptable or if additional information is required.
