At 1035 (PDT) on October 24, 2013, during At 1035 (PDT) on October 24, 2013, during a channel functional test (CFT), the intermediate radiation effluent monitor on the radwaste building failed an as found range check and was declared inoperable. A single range check was found out of tolerance low. The as found values on the remaining five ranges that the instrument spans were within the acceptance criteria. This monitor is one of three methods of declaring a general emergency due to offsite radiation releases originating in the radwaste building. Lower emergency classification levels are supported by a separate radiation monitor that was not impacted. The failure to complete the CFT on the intermediate range monitor with all ranges yielding satisfactory as found values represents a potential major loss of emergency assessment capability. This issue is being conservatively reported under 10 CFR 50.73(b)(3)(xiii). Efforts are underway to restore the monitor and an update will be made when the monitor is returned to service.</br>The licensee has notified the NRC Resident Inspector.</br>* * * UPDATE FROM EDAN ENGSTROM TO JOHN SHOEMAKER AT 2044 EDT ON 10/26/13 * * *</br>The intermediate radiation monitor on the radwaste building has been returned to within tolerance.
