AGREEMENT STATE REPORT - SOURCE DISCONNECT
The following was received from the State of Colorado via email:
"On January 7, 2020, DBI, Inc. reported a source disconnect for an industrial radiography source. The disconnect occurred on the first exposure of the day. The radiographer and assistant extended their boundaries and were able to restrict access at the location. The radiation safety officer was contacted and was successfully able to recover the source into a shielded container. The industrial radiography device was a QSA 880 delta and the source was an Ir-192 source with approximately 42 Curies.
"An onsite investigation will be scheduled in the future."
Event Report ID No.: CO200001

LOSS OF SEISMIC ASSESSMENT INSTRUMENTATION
"On January 7, 2020, Columbia Generating Station (CGS) experienced an equipment failure that resulted in a loss of the seismic assessment instrumentation. This is being reported as a major loss of emergency assessment capability in accordance with regulation 10 CFR 50.72(b)(3)(xiii). No other plant systems were affected.
"Compensatory measures have been implemented and will remain in place until the seismic system has been restored.
"The NRC resident has been notified."
Licensee received a design basis earthquake alarm, but no other local indication of seismic activity, nor on the U.S. Geological Survey website. Licensee compensatory measures include local readings on seismic instrumentation.

CHILL WATER SYSTEM INOPERABLE
"At 1341[EST], on 01/07/20, it was discovered all trains of the Chilled Water System were simultaneously Inoperable; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D). During this event, the Bravo train chiller was operating in a maintenance run and the temporary chiller was available and placed in service promptly to restore the safety function.
"The control room area cooling safety function was restored at time 1435 [EST] when one required train was declared Operable. There was no impact on the health and safety of the public or plant personnel.
"The NRC Resident Inspector has been notified."
* * * RETRACTION ON 1/23/2020 AT 1718 EST FROM JERRY COLLIER TO THOMAS KENDZIA * * *
"The purpose of this notification is to retract a previous report made on January 7, 2020, at 1909 EST (EN#54465). A subsequent evaluation determined that the Bravo train chiller, which was running at the time of the event, would be able to perform its safety function and was operable at the time of the event. Therefore, there was no loss of safety function.
"The NRC Senior Resident Inspector has been notified."
Notified R2DO (Coovert).
