HARTSVILLE NUCLEAR PLANT A - REPORTABLE DEFICIENCY - DIESEL GENEISTOR ENGINE PISTON SKIRT CASTINGS - HTRD-50-518/83-02, -520/83-02 The subject deficiency were initially reported to NRC-0IE, Region II, Inspector Ross Butcher on December 15, 1982, as NCR HTA MEB 8205. In compliance with paragraph 50.55(e) of 10 CFR Part 50, enclosed is our first interim report on the subject deficiency. We consider 10 CFR Part 21 applicable to this deficiency.
TVA has elected to defer construction activities for this praject.
Deferral does not mean that the project will be cancelled but that TVA is minimizing its expenditures and construction efforts until such time that TVA has sufficient information to indicate whether the project should be completed or cancelled. Therefore, we will not be submitting a final report for this nonconformar.ce until a final decision is made, regarding this project.
A 10-day extension on the submittal of this report was discussed with and granted by Ross Butcher on January 17, 1983 If you have any questions, please call Jim Domer at FTS 858-2725.
