LUCIE UNITS 1
AND 2 DOCKET NO. 50-335 AND 50-389 FOLLOWUP REQUEST FOR ADDITIONAL INFORMATION REGARDING GENERIC LETTER 92-08 "THERMO-LAG 330-1 FIRE BARRIERS" 1.0 REQUEST FOR ADDITIONAL INFORMATION (RAI) OF AUGUST 9, 1994 In the RAI of August 9, 1994, the NRC staff requested information regarding important barrier parameters, Thermo-Lag barriers outside the scope of the NEI
- program, ampacity derating, alternatives, and schedules.
No information was provided by the licensee in its submittal of November 4, 1994 to address the ampacity derating issue.
During a public meeting on March 14, 1995, with the licensees for the four lead plants for the resolution of Thermo-Lag issues, the staff responded to the question, "Will the resolution of the ampacity derating concern be deferred until agreement is reached on the appropriate testing protocol (i.e.,
IEEE P848)?"
The staff reiterated its position, which was previously stated'n the September 1994 RAI, that the ampacity derating concern could be resolved independently of the fire endurance concerns.
After a review of the tests performed under the draft IEEE standard
- P848, the staff transmitted comments which were designated to ensure the repeatability of test results to the IEEE working group responsible for the test procedure.
The licensee is requested to submit its ampacity derating evaluations, including any applicable test reports, in order to provide an adequate response to Generic Letter 92-08 reporting requirement 2(c).
2.0 REQUEST FOR ADDITIONAL INFORMATION OF DECEMBER 28, 1994 In the RAI of December 28, 1994, the staff requested information describing the examinations and inspections that will be performed to obtain the important barrier parameters for the Thermo-Lag configurations installed at St. Lucie.
In its response of March 28, 1995, the licensee stated that there is sufficient margin in existing ampacity derating calculations to bound any testing which-may be performed.
Finally, after an acceptable approach and test methodology has been agreed upon and testing has been performed the licensee will-review-these test results to determine if there is any impact on these calculations.
On May 18,
- 1995, members of the NRC staff held a telephone conference call with Nuclear Energy Institute (NEI) representatives on ampacity derating issues for Thermo-Lag fire bar riers.
The staff indicated that the latest IEEE P848 draft procedure can be used by licensees or NEI as the basis for an ampacity derating test program.
NEI agreed to review the Comanche Peak Steam Electric Station Unit 2 Safety Evaluation (SE) in order to develop a generic test program.
The memorandum dated May 22, 1995, which documents the subject telephone conference meeting, is attached for your information.
In addition,
a copy of the subject SE dated June 22,
- 1995, was sent to those licensees who rely on Thermo-Lag installations.
Please submit the anticipated test procedures or alternatively, a description of the analytical methodology including typical calculations which will be used to determine the ampacity der ating parameter s for the Thermo-Lag fire barriers that are installed at St. Lucie Units 1 and 2.
