>
of NRC requirements were identified.
The violations involved failures to report reactor protection system actuations to the NRC and violation of a
Limiting Condition for Operation.
In accordance with the " General Statement i
of Policy and Procedure for NRC Inforcement Actions," 10 CFR Part 2, Appendix C (1985), the violations are listed below:

g soon as practical and in all cases within four hours of the occurrence of
any of the following:
... (ii) Any event or condition that results in
'
manual or automatic actuation of any Engineered Safety Feature (ESF),
j including the Reactor Protection System (RPS)."
10 CFR 50.73, " Licensee Event Report System," also requires in part, a 30-day day written report of Peactor Protection System actuations.
'
The licensee's Technical Specification 2.9 states, "The plant protective
system is the reactor protective circuitry and the circuitry oriented towards protecting various plant components from major damage.
This system includes (1) scram, (2) loop shutdown, (3) circulator trip, and
(4) rod withdraw prohibit."

!
purified helium gas.
