50-278 Mr. George Lear, Chief Operating Reactors Branch #3 Division of Reactor Licensing Office of Nuclear Reactor Regulation United States Nuclear Regulatory Conmission Washington, DC 20555

Dear Mr. Lear:

In our October 30, 1975 response to your Septe'mber 10, 1975 Ictter to Mr. E. G. Bauer, Jr. dealing with relief valve line restraints at Peach Bottom Atomic Power Station Units 2 and 3, we indicated that we would transmit the results of a scheduled Unit #2 inspection.

An inspection of the Unit 2 discharge lines and restraints was conducted during a maintenance shutdown on November 17, 1975 A representative from our Engineering Ocpartment performed this investi-gation and found no evidence of damage or distortion in struts, hanger rods, pivot pins or discharge lines. His investigation did indicate, that the backup nuts on one U-bolt were backed away. On November 21, 1975, the torus water level was lowered to allow a closer look and to f acilitate any repairs that might be necessary. Only one nut was found actually loose and it was tightened. All other nuts were found in place and all gaps between piping and U-bolts were found to be within design specifications.

If you should desire any further information or details in this matter please contact us.

Very truly.yours, l -
