----------- [ Current event for TX_ComanchePeak_2 @ 100 %; RX Mode: Power Op ]

20180503 | TX_ComanchePeak_2 | LOSS OF EMERGENCY ASSESSMENT CAPABILITY |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53380

"During planned maintenance on Unit 2
Radiation Monitor 2-RE-4270 (Service Water Train B to Discharge Canal Rad Monitor), at 1220 CDT,
several other Unit 2 Radiation Monitors that are used for Emergency Action Level evaluation became nonfunctional for about 1 hour.

[ So they couldn't tell how radioactive the water they discharge was. A value we don't have access to.]

With these radiation monitors non-functional, all of the Emergency Action Levels associated with these monitors
could neither be evaluated nor monitored.

This unplanned condition is reportable as a loss of assessment capability per 10 CFR 50.72(b)(3)(xiii).
A PC11 computer reboot restored the affected radiation monitors to a functional status.

"The NRC Resident Inspector has been notified."
