Dear Mr. Sorensen:
The staff has completed its review of licensing topical report NEDE-31096-P, "Anticipated Transients Without Scram;
Response
to NRC ATWS Rule, 10 CFR 50.62",
submitted by the BWR Owner's Group.
NEDE-31096-P details conceptual designs to satisfy the 10 CFR 50.62 requirements for boiling water reactors.
The staff's safety evaluation of that report is enclosed for your information.
In order to complete the review of compliance with 10 CFR 50.62 for WNP-2, it is requested that you submit information as discussed above within 90 days of receipt of this letter.
As a participant in the BWR owners group topical report, you may reference the topical report in support of your plant specific submittal.
For the SLC system, you should choose one of the three alternatives and follow the conditions stated in the staff's SER.
For the ARI System, you may use the checklist (in Appendix A
of the staff's SER) to address your design requirements.
For the RPT System, you should indicate whether your installed system is the same as the Monticello design or the modified Hatch design.
The staff requires those utilities with other RPT designs to submit their schedule to upgrade their designs to either of the above approved designs or to demonstrate that their present design can perform its function in a reliable manner equivalent to the two approved designs.
