EN Revision Text: AGREEMENT STATE REPORT - DISCONNECTED RADIOGRAPHY SOURCE

The following was received from the Texas Department of State Health Services via email:

"On June 19, 2021 at 0851 CDT, a radiography team from an Oklahoma licensee working under reciprocity in League City, TX had a source disconnect at a temporary worksite. They were conducting radiography on new pipeline construction. While retrieving the source after a shot, the source did not return to the camera. It appears the guide cable broke. The source was still in the collimator. The Radiation Safety Officer is present and they put up a barrier and no other personnel are in the area. No extra dose to the radiographers occurred. The device is a QSA Global 880, serial number D14864 containing a 90.1 Ci Iridium-192 source, serial number 31423m. The manufacturer, QSA Global, quickly retrieved the source around 1800 CDT. The manufacturer took the camera and associated equipment to complete a full inspection. Additional information will be provided as required by SA-300."

EN Revision Text: LOSS OF TECHNICAL SUPPORT CENTER CAPABILITY

"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the Technical Support Center (TSC) supply fan belt had failed, which affects the functionality of an emergency response facility.

"Corrective maintenance activities will be performed to restore functionality. The work includes replacing the failed belt and restarting the TSC supply fan. The work duration is approximately 8 hours. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures. [The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency.]

"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector and Illinois Emergency Management Agency have been notified."

10 CFR 50.55(e) REPORT REGARDING ELECTRICAL CONSTRUCTION AND MEASURING AND TEST EQUIPMENT CONTROL

The following is a synopsis of information received via E-mail:

The individual informing the Commission is Michael J. Yox, 7825 River Road, Waynesboro, GA 30830.

The activities which fail to comply include construction processes including, installation of some electrical and mechanical commodities, and control of measuring and test equipment at the Vogtle 3 and 4 construction project.

The primary construction firm for the Vogtle 3 and 4 construction project is Bechtel Power Corporation (Bechtel).

This report is being provided based on construction nonconformances including, installation of some electrical and mechanical commodities, and control of measuring and test equipment for Vogtle Units 3 and 4. The nonconformances affect cable separation and other raceway structural elements. The extent of condition for the measuring and test equipment issue is under evaluation and may impact additional safety-related work.

The identified construction nonconformances are a small fraction of the overall structures and components. There is no specifically identified substantial safety hazard (SSH) for these nonconformances. The nonconformances identified affect some safety-related components and based on this it was conservatively judged that the issues could be related to an SSH. These issues were discovered while the facility is under construction. The identified conditions will be corrected prior to completion of the facility.

The evaluation for this report was completed on June 24, 2021.

As stated above, there are no specifically identified basic components that have been identified to contain a defect for Vogtle Units 3 and 4. The nonconformances identified affect some safety-related components and based on this it was conservatively judged that these conditions involve a failure to comply that could be related to an SSH.

The corrective action which has been, is being, or will be taken include: Comprehensive extent-of-condition reviews and correction of identified conditions are being conducted. The actions to identify and resolve the nonconforming conditions are in process and will be completed in accordance with the site corrective action program. Bechtel, and other subcontractors as needed, will implement actions to correct the identified conditions and ensure that processes are in place to avoid future occurrences. Southern Nuclear Operating Company (SNC) is the organization responsible for ensuring Bechtel and the other subcontractors complete the required actions to correct the nonconforming conditions and ensuring that processes are in place to avoid future occurrences.
