JUL 271989 Ms. Mary Ott Post Office Box 2621 Duxbury, Massachusetts 02331
Dear Ms. Ott:
Enclosed are the excerpts of NRC Inspection Report No. 50-293/82-16 that I said I would send you. The report should help you understand why the 1982 Traver-sing In-Core Probe (TIP) system event resulted in an emergency declared and the 1989 TIP system event did not.
The report shows that in the 1982 event, the
.'
TIP detector was withdrawn well beyond its shield such that it created high radiation in general areas of the Reactor Building outside the TIP room. As the NRC Pilgrim Bi-Weekly Status Report, dated June 7,1989 shows, the slight over withdrawal of a TIP detector on May 31, 1989, did not result in any sig-nificant radiological hazard in the Reactor Building general areas, since the detector remained inside the normally locked TIP raom.
Thus, the safety sig-nificance of the 1989 event was minor compared to the 1982 event.
Also enclosed for your information is NRC Inspection Report No. 50-293/89-05, dated June 9,1989.
The summary, as well as Paragraph 2.3.3, of the report contain NRC comments on reactor building door failures.
Sincerely, Orig!*g geped 9/
