Dear Sir:

APR 22198A -

a smst ra;uist numer DEasE BWiouf M ,

Docket 50-305 \ T100 /

Operating License DPR-43 Kewaunee Nuclear Power Plant 'D' Radiation Monitoring System - R-1 Failure This is to inform you of the failure of the Control Room Area Monitor (Channel R-1) of our radiation monitoring system and our immediate 'and long-term corrective actions. We consider the equipment failure significant, however, it is not reportable per Technical Specifications.

Upon indication of Channel R-1 failure, the Operations Staf f placed a portable radiation monitor in service in the Control Room. A check of this monitor was performed daily. Monthly testing was not performed as required by Technical Specifications (Table 4.1-1 Item 19) since no alarms were available on the portable instrument to test.

Replacement parts for R-1 were ordered and delivery is expected within six to nine months. Due to the long delivery time, an off-the-shelf area monitor (Dosimeter Corporation AM-2) with visibic and audible alarms was purchased, i calibrated, and placed in the Control Room. This monitor will be checked daily and tested monthly in accordance with Technical Specifications Table 4.1-1 until R-1 is repaired and placed in service.

l l Very truly yours ,
