| AGREEMENT STATE REPORT - DAMAGED GAUGE The following was received form the California Radiologic Health Branch (RHB) via email: "On 7/17/2020, licensee's RSO [(Radiation Safety Officer)] contacted RHB to report an incident in which a portable nuclear gauge (Humboldt 5001EZ SN: 2919, 11 mCi Cs137, 44 mCi Am241:Be) was damaged by a construction truck at approximately 2330 PDT on 7/16/2020. The RSO secured the gauge after notification by the gauge technician and transported the gauge to the licensee's permanent storage location. The RSO determined and confirmed to RHB that the source rod was able to be retracted into the shielded position after the incident. The RSO performed a radiation survey and reported readings of 0.099 mR/hr at 1 meter. RHB will be following up with this investigation." California 5010 Number: 071720 |

| FAILED RADIATION DETECTOR "Radiation monitor RE-69, 'Guardhouse Area Radiation Detector' was found failed on operator rounds. RE-69 is a category A1 piece of equipment that provides the sole means of indication for a parameter used to directly assess emergency action level (EAL) RA3.1, 'dose rate greater than 15 mR/hr in either of the following areas: Control Room (R-1), Central Alarm Station (R-69).' A compensatory measure was subsequently established and the ability to assess EAL RA3.1 has been restored." There was no impact on the health and safety of the public or plant personnel. The NRC Senior Resident Inspector has been notified. |
