Your July 8,1997, letter included a commitment to resolve all Thermo-Lag fire barrier issues before the restart (Mode 4) of the Millstone Nuclear Power Station, Unit No. 2, from the current outage.
The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed your submittals. Your November 13,1998,, letter summarized the final corrective actions being taken to address the various Thermo-Lag issues which include removing Thermo-Lag, rerouting cables, using an attemative cooling water source for the emergency diesel generator coolers, and upgrading some Thermo-Lag inatallations to 1-hour and 3-hour ratings. The staff has determined that NNECO has provided the information requested in GL 92-08 and that the activities related to TAC Number M85571 are complete.
Please advise the NRC staff in writing if you change the plans or schedule detailed in your November 13,1998, submittal relating to the resolution of the concems identified in GL 92-08 l

provides the Office of Management and Budget clearance for this inforrr stion request.
There remain open issues involving ampacity derating caused by the use of Thermo-Lag 330-1 that have emerged as a result of the GL 92-08 review effort. The resolution of these ampacity derating issues is being traced by TAC Number MA3392. In addition, you have requested four exemptions from 10 CFR Part 50, Appendix R, by letter dated July 12,1998.
One of the exemption requests, relating to the charging pump room, is an issue that emerged from GL 92-08. The staff is evaluating the exemption requests, including the issue that i
emerged from the GL 92-08 review, and its ort is being tracked by TAC Number MA2416.
