Subject:
Deferral of ATWS Rule (10CFR50.62) Technical Specifications in Reference (b) Vermont Yankee provided its proposed Technical Specifications for the ATWS Rule, 10CFR50.62, as requested by NRC in Reference (c). NRC comments on the proposed changes were issued in Reference (d), which included a request for updated Technical Specification pages.
Following meetings between NRC and Vermont Yankee, documented in Reference (e), Vermont Yankee submitted updated Technical Specifications pages in Reference (f). Since submitting Reference (f), review of this proposed change has been delayed by other higher priority matters and resolution of concems regarding alternate rod injection (ARI) system diversity.
Vermont Yankee is operatirig in full compliance with the requirements of the ATWS Rule. As documented in Reference (g), Vermont Yankee's recirculation pump trip system is based on the
- Monticello design" and fully meets the requirements of 10CFR50.62(c)(5). Additionally, Vermont Yankee plant procedure OP4611 requires that the standby liquid control (SLC) tank boron concentration be maintained such that the SLC system meets the performance criteria of g
10CFR50.62(c)(4). Finally, the ARI system was modified during Vermont Yankee's 1995 refueling h
outage to fully comply with the requirements of 10CFR50.62(c)(3) as documented in Reference (h).
NRC review of Vermont Yankee's compliance with the requirements of the ATWS Rule are D
