Oyster Creek Nuclear Generating Station (OCNGS)
Operating License No. DPR-16 Docket No. 50-219 Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License No. DPR-50 Decket No. 50-289 Survey of Deterioration and Repair of Concrete in Nuclear Power Facilities In response to the NRC's letter to GPUN, dated March 11, 1992 (C311-92-3046),
regarding survey of deterioration and repair of concrete in nuclear power facilities, enclosed are completed survey forms for THI-l and OCNGS.
This information is provided to assist in NRC development of. a concrete repair manual for concrete structures in nuclear power plants, as part of its Nuclear Dlant Aging Program.
The completed survey forms are based on reviews of plant records and discussions with appropriate personnel. This information has not been compiled in accordance with any quality assurance program activity and as'such should be utilized for statistical survey purposes only.
If any additional information is needed, please contact Mr. David Distel at (201) 316-7955.
