Northern States Power Company 414 Nicone Mall Minneapohs, Minnesota 55401 Telephone (612) 330-5500 August 11, 1982 R L Spessard, Director Division of Project and Resident Programs Region III U S Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, IL 60137 MONTICELLO NUCLEAR GENERATING PLANT Docket No. 50-263 License No. n?R-22 Response to Item of Noncompliance In response to your letter of July 12, 1982 which transmitted Inspection Report No. 50-263/82-03, the following is offered:
Violation 10 CFR 50.72(a)(8) requires each licensee of a nuclear power reactor to notify the NRC Operations Center as soon as possible and in all cases with-in one hour by telephone of the occurrence of any accidental, unplanned, or uncontrolled radioactive release.
Contrary to the aboec, an accidental radioactive release was determined at 11:00 p.m. on May 3, 1982, to have occurred earlier that day and the release was not reported to the NRC Operations Center until 8:00 a.m. on May 4, 1982.
Response
The event resulting in the unplanned radioactive release was reported to the Commission in writing on June 3, 1983 as Licensee Evgnt Report 82-06.
As noted in that report, the release totalleu
?. 2 x 10 curies using conservative calculational methods and resulted from a leaking RHR heat exchanger.
The event was not reported within one hour of verification that an unplanned release had occurred. We believe this was due to the fact that operations personnel were concentrating on identification and isolation of the leaking heat exchanger and the Technical Specification requirements for operability of this equipment.
Because of the insignificant concentrations of radio-activity in the water released, it was not immediately obvious that this constituted an " unplanned release".
Section 50.72 does not provide threshold levels for reporting of accidental, unplanned, or uncontrolled radioactive releases. Therefore, even though the release constituted less than 1/1000 of the Technical Specification limit for permissible liquid releases, the event should have been reported in accordance with the regulation.

sessions the immediate reporting requirements of 10 CFR Part 50,
,/
.(
Section 50.72.
We will specifically point put that unplanned releases of any magnitude require reporting withiq one hour of confirmation.
j' Also, through discussions of.this event ge believe our personnel have now been sensitized to strict compliance,with" Section 50.72 and failures to meet the one-hour reporting requirement are not likely to reoccur.
Existing pior.t diractives are in full compliance with the one-hour reporting requirements of the Commission.

Please contact us if you have any questions concerning the actions planned to prevent recurrence of this violation.
