AGREEMENT STATE REPORT - STUCK GAUGE SHUTTER
The following was received via email from the state of Texas:
"On September 25, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee [Graphic Packaging] that the shutter on a Berthold model P2602-100 gauge containing 100 milliCuries of Cobalt-60 failed to close during the required maintenance check. The gauge shutter is stuck in the open position, which is the normal operating position for the gauge and does not pose an increased exposure risk to any individual. The gauge is attached to a second floor crystallizer ash tank recirc line and is not accessed during system operation.
"The licensee stated that they were in the process of contacting the manufacturer for repairs or replacement of the gauge. Additional information will be provided as it is received in accordance with SA-300."

CONTROL BUILDING CHILLERS IN UNANALYZED CONDITION
"At 1200 CDT on September 25, 2018, while the plant was in MODE 1 at 90 percent power, it was identified that an additional condition existed which had not previously been considered in developing the compensatory measures implemented for design flaws and single point vulnerabilities associated with the Control Building Chilled Water System. Specifically, a 20 minute 'quick restart timer' on Control Building Chillers that have analog control systems (HVK-CHL1A & 1B) would prevent the chillers from starting in specific scenarios.
"The recommended compensatory actions to address the new condition were implemented at 1235 CDT on September 25, 2018.
"Currently the Chilled Water System is otherwise operating as designed. Operator actions are in place to ensure the plant meets all required design safety system functions. Work is currently underway to identify and correct all design vulnerabilities.
"The [NRC] Senior Resident Inspector has been notified."
This was identified by engineering during an extended condition search.
