,Mr. A. W. Dromerick, a member of your staff, has asked that we ex;Jain why the completion of the Reactor Coolant System has been revised, and how much delay can we attribute to item 4 on our IIst, hanger design and final stress analysis. The major Reactor Coolant System problems were:
! modifications to the RTD by-pass valve resulting from the stress analysis and to system related trip valves, review of weld joint procedures and i quality control research on alleged undergrinding of weld joints. The potential delay attributable to hanger iesign and final stress analysis is approximately four weeks. .
Since our September 26, 1978 letter, it became necessary to loan a North Anna Unit 2 Reactor Coolant Pump motor to Surry Power Station. The maximum potential delay attributable to this new problem is approximately four weeks.
