Dear Mr. White:
SUBJECT:
ATWS RULE (10 CFR 50.62):
PLANT SPECIFIC REVIEWS (MPA:
A-20)
Re:
Browns Ferry Nuclear Plant, Units 1, 2 and 3
Paragraph (C)(6) of 10 CFR 50.62 requires that all BWR licensees submit information sufficient to demonstrate the adequacy of the systems addressed in Paragraphs (C)(3), (C)(4), and (C)(5), for their respective facilities.
These systems include the alternate rod insertion (ARI), standby liquid control (SLC), and recirculation pump trip (RPT) systems.
If your utility was a participant in the BWR Owners Group licensing topical report (NEDE-31096-P) submitted January 14, 1986, in response to 10 CFR 50.62, you may reference this document to support your plant specific submittal.
For your information, we have enclosed a copy of the staff's Safety Evaluation (SE) of the topical report (Enclosure 1).
With regard to the SLC system, your submittal should address the conditions stated in the staff's SE for the system alternative you have selected.
For the ARI system, you may use the checklist contained in Appendix A of the SE to address the details of your design and its conformance to ARI design basis requirements and objectives.
Regarding the RPT system, you should indicate whether the systems installed at Browns Ferry Nuclear Plant, Units 1, 2 and 3, are based on the "Monticello design" or the "modified Hatch design".
If your systems are not based on either of these approved designs, you should submit your schedule for upgrading the system to one of these
- designs, or else demonstrate that the existing systems can perform their functions with equivalent reliability.
If your utility did not participate in the BWR Owners Group topical report, or if your utility was a participant but has chosen to deviate from the approved design alternatives contained therein, you are requested to submit detailed design information.
This information should address all aspects of 10 CFR 50.62 "Rule Considerations Regarding Systems and Equipment Criteria" published in Federal Register Volume 49, No.
124 dated June 26, 1984, and Generic Letter 85-06, "guality Assurance Guidance for ATWS Equipment that is not Safety Related".

If you have special implementation and scheduling requirements concerning the above requested action, please provide us with this information so that we can incorporate your concerns in our planning.
