ENCLOSURE 1
NOTICE'P VIOLATION r
.Florida Power and Light Company Docket Nos, 50-250, 50-251 Turkey Point, Units 3 and 4
'uring the Nuclear Regulatory Commission (NRC) inspection conducted on October 28 through November 8,
1991,- violations of NRC requirements were identified.
Zn accordance with the
>>General Statement of Policy and Procedure for NRC Enforcement Actions,>>.
10 CFR Part 2, Appendix C (1991), the violations are listed below:
A.
B ~
10 CFR Part 50'ppendix Bi Criterion ZIZZ Design Control,
. states in part, that design control measures shall provide for verifying or checking the adequacy of design,...be established for the identification and control of design interfaces and for coordination among participating organizations.
Florida Power and Light Company>s implementing Quality Znstruction, QZ 3-PTN-1, Design Control, requires that design control measures shall provide for verifying or checking the adequacy of
- design, such as by performance of design
- reviews, or by performance of a suitable testing program.
Contra~ to the above, adequate controls were not in place during the exchange of engineering data between the vendor and the Florida Power and. Light Company staff to insure that complete and accurate programmable constants and programmable components were installed.in the Eagle 21 system.
Between September 27 and October 5, 1991, the-licensee identified that the Eagle 21 portion of the Reactor Protection System (Tuning Constants, Resistance Temperature Device constants, and Scaling Factor) contained non>>plant specific settings that were not acceptable for proper operation of Overpower Delta T, and Overtemperature Delta T.
This is a Severity Level ZV violation (Supplement 1).
~
Technical Specification 2.2.1 requires reactor trip system instrumentation and interlock setpoints be set consistent with
~ the trip setpoint values shown in Table 2.2-1.
Zn TS Table 2 '
lg Overtemperature Delta T refers to Note 1, and Overpower
'Delta T refers to Note 3.
Table -2.2-1 Note 1 and Note 3, both define Delta T Subzero as the indicated Delta T at rated thermal power.
Contrary to the'bove, on October 7,
- 1991, the licensee identified that the design Delta T Subzero (56.1.degrees F) was being used in lieu of the indicated Delta T Subzero for computing the Overpower Delta T and Overtemperature Delta T
setpoints.
This is a Severity Level ZV violation (Supplement 1).
