- Ich require resolution prior to rectart. Three of these items have bee: :sused and one remains opent 1)
The licensee is continuing to study the impact of the new ARS on the structural items and piping systems and has committed to recolve this issue before restart of Unit 2.
STATUS:
Closed for restart. The issue of the impact of the new amplified response spectra was reviewed in Inspection Report 89-42, dated February 26, 1990.
At that time, two issues remained open; one is now closed for restart and the other has been closed.
The first open issue was the evaluation of the drywail steel platforms.
It was closed for restart pending TVA's performance of a fir.a1 confirmatory evaluation when the generation of the final pipe support loads from the IED 79-14
(
program was completed.
The complettnn of thia final evaluation was not required prior to restart; however, TVA intends to complete it prior to restart.
This work is being tracked by NCO 86-0326-158.
The second open issue was the evaluation of Class I HVAC ductwer(.
This issue was closed pending completion and submittal of TVA's evaluation of the Class I ductwork for the chimney.
This work was completed and the issue closed by NRC letter, dated August 22, 1990.
2)

The licensee agreed to provide this information when it becomes available.
STATUS:
Closed. This information was submitted by letter, dated October 6, 1989. The issue was closed by NRC in Inspection Report 89-62, dated February 16, 1990.
3)
Because Appendix J compliance has been deloted from the current Browns Fctry FSAR, the etaff was not able to review the original design basis and criteria for the primary systems.
The licensee again documented its compliance to Appendix J in its submittal dated June 23, 1989.
(No TVA action identified.)
STATUS:
Closed. This information was submitted by letter, dated June 23, 1989.

- 4) When the dynamic model of the RPV internals and supports was developed, the licensee incorrectly assumed the existence of seismic restraints at the lower end of CRD housings.
This inspection finding was confirmed by the original design drawing and a field walkdown. The licensee is developing a modification and will report to the staff when the modification has been completed. This open issue is considered an unresolved item (URI 89-31-01) for Inspection 50-260/89-31 and will be reviewed in a followup inspection before the restart of Unit 2.
