SUBJECT:
CONFIRMATION OF ACTION LETTER This refers to your " pool type" non-power reactor ;nd the April 28, 1993, event you reported to the Nuclear Regulatory Commission (NRC) whereby you inadvertently modified the circuitry on the reactor console and, as a result, operated the reactor for some period of time on April 28 without required circuitry for some of the reactor protection systems (e.g., reactor scram signal).
This event was reported to the NRC on April 29, 1993.
Pursuant to a telephone conversation between Dr. Bruce S. Mallett, of this Office, and you on April 29, 1993, it is our understanding that you have taken or will take the following actions:
1.
Placed the reactor in the shutdown condition as of April 28, 1993, and will continue to maintain the reactor in a shutdown condition until you have evaluated the cause of the event, determined the extent of the effect on any circuitry on the reactor console and reactor safety systems.
2.
Maintain the reactor in the shutdown condition until your Reactor Safety Committee has reviewed the evaluation and corrective actions implemented.
3.
Maintain the reactor in the shutdown condition and not initiate restart of reactor operation until you have discussed the results of your evaluation and your implemented corrective actions with the NRC Region II Regional Administrator or his designee.
Pursuant of Section 182 of the Atomic Energy Act, 42 U.S.C. 2232, and 10 CFR 2.204, you are required to:
1.
Notify me immediately, if your understanding differs from that set forth above, 2.
Notify me if for any reason you cannot complete the actions within the specified schedule and advise me in writing of your modified schedule in advance of the change, and 3.
Notify me in writing when you have completed the actions addressed in this Confirmatory Action Letter.
Issuance of this Confirmatory Action Letter does not preclude issuance of an order formalizing the above commitments or requiring other actions on the part of the licensee.
Nor does it preclude the NRC from taking enforcement action for violations of NRC requirements that may have prompted the issuance of this 9305260233 930430
