The following information was received from the State of California via email:
"On September 14, 2017, [The RSO] of Southwest Calibration & Training notified the RHB Brea office that United Inspection & Testing, Inc., RML # 4788-33, had a Troxler, 3411B, serial #6644 radioactive gauge run over and damaged. On September 14, 2017, RHB Brea contacted [The RSO] of United Inspection & Testing, Inc. [The RSO of United Inspection & Testing, Inc.] informed our office that the radioactive gauge had been run over by a backhoe on the afternoon of September 13, 2017 at approximately 1400 [PDT], at the intersection of Banana Street and Daurin Street at a construction site in Fontana, CA. As a result of the accident the radioactive gauge had the handle broken off. The RSO was able to return the Cs-137 source to its shielded position, but it could not be locked in the shielded position due to the damage to the gauge. The authorized user of the gauge was also struck by the backhoe and died of his injuries. [The RSO of the United Inspection & Testing, Inc.] retrieved the gauge from the accident site and transported it to Southwest Calibration & Training to be inspected. [The RSO] of Southwest Calibration & Training reported that the Troxler radioactive gauge read 0.9 mR/hr at 1 foot. The gauge was extensively damaged and may not be repairable."

"On September 21, 2017 at 1730 [CDT] the Control Room Emergency Ventilation Air Condition (CREV AC) system was declared inoperable due a refrigerant leak from the air conditioning compressor. As a result, Technical Specification 3.7.5 Condition A was entered for Units One and Two.
"The CREV AC system maintains a habitable control room environment and ensures the operability of components in the control room emergency zone during accident conditions.
"This notification is being made in accordance with 10CFR50.72(b)(3)(v)(D) because the CREV system is a single train system. The loss of CREV AC could impact the plant's ability to mitigate the consequences of an accident."
