ENCLOSURE 1
NOTICE OF VIOLATION Florida Power and Light Company Turkey Point Units 3 and 4'ocket Nos.
50-250 and 50-251 License Nos.
DPR-31 and DPR-41 The following violations were identified during an inspection conducted on April 23-26, 1985.
The Severity Levels were assigned in accordance with the NRC Enforcement Policy (Title 10 Code of Federal Regulations Part 2, Appendix C).
Title 10, Code of Federal Regulations, Appendix B, Criterion V,
as imple-mented by paragraph
- 5. 1 of the accepted quality assurance
- program, requires activities affecting quality to be accomplished in accordance with proce-
- dures, and those procedures to contain appropriate acceptance criteria.
American National Standards Institute's (ANSI) Standard ANSI B31.1 (1977),
Paragraph 108.5. 1.A, states "Bolts and bolt studs shall extend complete through the nuts." American Society of Mechanical Engineers (ASME) Standard Section III, Division 1, Subsection NF (component supports),
Paragraph NF-4711, states "All bolts or studs shall be engaged for the full length of thread in the nut."
ASME Section III, Division 1, Subsections NB, NC, and ND (classes 1,
2, and 3), Paragraph 4711, states "The threads of all bolts or studs shall be engaged in accordance with the design."
ANSI B16.5 (1977),
- Standard, specifies lengths of stud bolts for standard flanges.
2.
Contrary to the
- above, procedures did not contain appropriate acceptance criteria in that the licensee had no documented procedures prescribing thread engagement requirements.
This lack of documented procedural require-ments in the area of thread engagement resulted in numerous examples of bolted connections on safety-related components and piping systems with at least one full thread less than full engagement.
This is a Severity Level IV Violation (Supplement I).
Title 10, Code of Federal Regulations, Part 50.55a(g) requires that inservice testing to verify operational readiness of pumps and valves, whose function is required for safety, be accomplished in accordance with Section XI of the American Society of Mechanical Engineers Boiler and Pressure Vessel (ASME B&PV) Code.
ASME BKPV Code,Section XI, 1980 edition through Winter 1981 addenda has been identified as the applicable code for inservice testing.
ASME BLPV Code,Section XI, paragraph IWV-1100, requires inservice testing to verify operational readiness of certain Class 1, 2, and 3 valves (and their actuating and position indicating systems) in light-water cooled nuclear power plants, which are required to perform a specific function in shutting down a reactor to the cold shutdown condition or in mitigating the consequences of an accident.
Safety injection accumulator pressure relief valves have been identified as being required to mitigate the consequences of an accident.
