Dear Sirs:
The Idaho State University AGN-201 Reactor Facility (License # R-110, Docket # 50-284) is officially self-citing a violation. In accordance W our Technical Specifications section 6.9.2.a.(2), the reactor facility is requi ed to report to the USNRC when a Limiting Condition of Operation (LCO) is found C*se of to npf meet the requirements of Technical Specification Section 3.2.d.
Engineering h7ao The details of the events that led to the violation, the corrective actions s m so60 taken, the corrective action to be taken, and the date of full compliance are described in the enclosed report.
The facility will notify the USNRC after full compliance has been achieved.
If you have questions regarding the details of the violation, please feel free to contact me at (208) 236-3637 or Dr. Alan Stephens (Reactor Administrator) at (208) 526-4907.

. REPORT OF SELF-CITED VIOLATION FOR LICENSE #R-110, DOCKET #50-284 March 24,1995 Item A: Failure to maintain Nuclear instrument (NI) Channel #2 within the Limiting Condition of Operation set points as described in the facility Technical Specifications (Ref.10CFR50.36.c.(2) and Idaho State University Technical Specification Section 6.9.2.a.(2)).
- 1) Backoround of violation: On March 10,1995, while performing surveillance on NI Channel #2, the low level set point was discovered to be tripping at a value of 1.9 X 10'" amps. This is a value less than that specified in the facility's Technical Specifications 3.2.d (i.e. 23 X 10'" amps). The reactor had been operated several times since the last time the NI Channel #2 low level set point was verified on April 20, 1995. This is a violation of facility's Technical Specification Section 6.9.2.(a). The United State Nuclear Regulatory Commission (USNRC) was informed of this violation on the next working day (March 13,1995).
- 2) Reason for violation: The reason the NI Channel #2 low trip set point was found to be less than the prescribed value (as per the Technical Specification) for the LCO was due to instrument drift.
- 3) Corrective actions taken and results achieved:
The low trip set point for Ni Channel #2 was adjusted immediately to meet the LCO of the Technical Specifications. The surveillance for NI Channel #2 was completed successfully.
- 4) Additional corrective actions to be taken:
The Reactor Safety Committee will hold a meeting by June 30,1995 to approve a Technical Specification change request of Sections 3.2 and 6.9.2.a.(2). This change request will provide for remedial actions of adjusting the LCO's set points without having to file a Reportable Occurrence. Once the Technical Specification change is approved, this request will be forwarded to the USNRC for final approval.
- 5) Date when full comoliance will be achieved: Full compliance will be achieved when the USNRC approves the Technical Specification change request.
