STN 50-561 VENDOR: Babcock & Wilcox Company (B&W)
SUBJECT:
SUMtfARY OF 11EETING TO DISCUSS RESPONSES TO OUTSTANDING ISSUES ON BASR-205 On August 3,1977, representatives of B&W and our staff met in Bethesda to discuss B&W's responses to outstanding issue numbers 1, 5, 6, and 11 reported in section 1.6 of the staff's July 8,1977 Report to the ACRS on BSAR-205.
An attendance list is enclosed.
Issue No.1, Seismic Qualification of Mechanical Equipment-The staff noted that this issue was resolved at the preliminary design stage by B&W's response to staff position number 110.43.
Issue.No, 5, Fuel Surveillance Program-This was discussed in a separate meeting session with the Assistant Director for Light Water Reactors, Division of-Project Management. The conclusion of this discussion was that fuel surveillance would no longer be an open issue in the BSAR-205 review. While we will require surveillance examination of the first two full reactor cores of Mark C fuel, we will require each referencing applicant to perform the surveillance program, or portion thereof that remains to be conducted, at the appropriate time.
Issue No. 6, Overpressure Protection-B&W proposed to suumit a iimiting pressure versus temperature graph which will be conservative for all BSAR-205 reactor vessels.
They believe that this curve will show that for vessel temperatures at which the reactor coolant system is protected only by the pressurizer relief valve, the relief valve setpoint and relieving capacity will be adequate to maintain the vessel material within Appendix G limits. The staff, including representatives from both the Reactor Systems Branch and the Materials Engineering Branch, agreed to consider the B&W approach when the written proposal is submitted.
Regarding reactor coolant system protection when the decay heat removal system isolation valves are open, the staff asked several questions about the operation of the valves and the valves' relief capacity for various conditions of inadvertant heat or liquid addition to the system.
B&W agreed to provide additional information in the near future.
Issue No. II, Compliance with IEEE 323-1974 for Makeup Pump and Decay Heat Removal Pump Motors-B&W pointed out that they intended to comply 3
with Standard No. 323. These motors are to be purchased items, and B&W

expects their vendors to develop methods and procedures for' compliance and to obtain appropriate approvals from the NRC. The staff pointed out that B&W would be required to iaake appropriate commitments to comply with Standard No. 323, and that B&W would ultimately need to document the methods and acceptance criteria in BSAR-205, even if this documentation were incorporated by reference to other reports.
B&W agreed in principle to this requirement, and said that a new response would be submitted shortly.
