Subject:

Reporting Requirements of 10 CFR Part 50, Sections 50.72 and 50.73, and Standard Technical Specifications (Generic Letter No. 83-43 ) Section 50.72 of Title 10 of the Code of Federal Regulations has recently been revised and will become effective January 1,1984 A new Section 50.73 of Title 10 of the Code of the Federal Regulations has recently been added and it will also become ef fective January 1,1984. Section 50.72 revises the immeciate notification requirements for operating nuclear power reactors. Tne new section 50.73 provides for a revised Licensee Event Report System. Copies of each of these sections to 10 CFR Part 50 are enclosed for your i nf ormation. Since paragraph (g) of Section 50.73 specifically states that: "the require-ments contained in this section replace all existing requirements for licensees to report ' Reportable Occurrences ' as definec in individual plant Technical Specifications," the reporting requirements incorporated into the " Admin-istrative Controls" section of your f acility 's technical specifications may recaire nocification. Also, the definition " Reportable Occurrence" may need to be replaced by a new terr, " Reportable Event." We will make these cnanges in tne current version of Standard Technical Specifications (STS) for all naclear ;o er reactor vendors and in the technical specifications for plants not yet licensed. Enclosec are model technical specification in STS format showing the revisions which you should make in the " Administrative Centrol" and " Definitions' sections of your f acility 's technical specifications to implement these regulation changes. Other conf orming changes tc your technical specifications will be recuireo to reflect the revised reporting requirements. For example, technical specifications requiring a Licensee Event Report rather than a Special Report for operating conditions where the specific activity limits of the reactor coolant are exceeced should be changed to reflect the need for a Special 16 4-174 -8312190371 O p
