MM 0 3 BBS Florida Power Corporation ATTN: Mr. Walter S. Wilgus Vice President Nuclear Operations P. O. Box 14042, M.A.C. H-2 St. Petersburg, FL 33733 Gentlemen:

SUBJECT: REPORT NO. 50-302/84-33 Thank you for your response of March 1, 1985, to our Notice of Violation issued on January 31, 1985, concerning activities conducted under NRC Operating License No. DPR-7 Our review of your response to Violation 84-33-01 has reaffinned our position

that the violation did occur. In your response, you stated that followin implementation of the new Radiological Effluent Technical Specifications TS)(g onthe July 1,1984, you realized that you would not be able to comply with the actions of TS 3.7.13.5.b for the waste gas decay tanks (WGDTs) using the normal system configuration of the waste gas system. You further stated that a telephone conversation was held between FPC and MRC on July 10, 1984, in which a resolution of this conflict was obtained. This resolution, which was discussed with an NRC licensing reviewer, was that adding dilution nitrogen required some admission of waste gas into the WGDTs since nitrogen could only be added via the waste gas heade We have discussed this telphone conversation with the reviewer involved, Mr. Charles Willis. Mr. Willis stated that his position was based upon the understanding that the waste gas header was going to be isolated from everything except the affected WGDT during the nitrogen addition process and that the small amount of waste gas that was added during the nitrogen addition process was only that waste gas present in the header at the start of the process. This under-standing is strengthened by a statement in your telecon/ meeting summary dated July 10, 1984, which stated: "This method of nitrogen addition also introduces the small amount of waste gas which is in the header to the WGDT."

Mr. Willis stated that he was unaware that your actual intention was to leave the waste gas header on line, thus allowing the continued admission of waste gas to the decay tank. As a result, during the period of December 13-14, 1984, when attempts were being made to reduce the oxygen concentration in the tanks by adding nitrogen through the waste gas header, your activities did not reduce the oxygen concentration but, instead, caused a continuing increase in both hydrogen and oxygen concentrations. This increase resulted in a situation that continued to exceed the TS limits for permissible gas concentration The situation described above illustrates the need to develop written and com-plete requests for TS resolutions, except in those infrequent instances where expeditious resolution is required due to operational necessity. Your coment concerning the omission of the words "begin to" in the Notice of Violation is noted. However, this omission is not significant since it does not change the intent of the T gg72 g g % M o2 G W! Q
