DPR-58 and DPR-74 Special Report Technical Specification 3.3.3.1 United States Nuclear Regulatory Commission Attn: Document Control Desk 11555 Rockville Pike Rockville, Maryland 20852 August 26, 1993 Gentlemen:

This Special Report is being submitted in accordance with Technical Specification (TS) 3.3.3.1, Action Statement 22A, to inform the NRC that the Containment 650'levation High Range Train. 'A'rea Radiation Detector, 2-VRA-2310, was inoperable longer than allowed by the Action Statement.

On July 10, 1993 at 1330 hours0.0154 days <br />0.369 hours <br />0.0022 weeks <br />5.06065e-4 months <br />, the detector was declared inoperable due to the inability to perform the channel checks required by the surveillance requirements. Although the detector was still functional, it was considered and declared inoperable. The redundant instrumentation was confirmed to be operable.

However, the Special Report required by TS 3.3.3.1 was not submitted to the NRC when the detector remained inoperable in excess of the 7 day Action Statement requirement.requirement The failure to comply with the Special Report was discovered on July 30, 1993, and is rectified by transmittal of this letter.

This event resulted from the repair action not being prioritized in accordance with the applicable LCO restoration requirement, coincident with the failure to identify the need for a Special Report. This is attributed to: 1) ineffective communication of the TS Action Statement requirement via the Work Request,. which,led.to a,,priority code assignment that was not consistent. with the time limit or special reporting requirements imposed by the TS, and 2) subsequent reviews did not detect the oversight.
