On 03/11/2019 planned maintenance activities will be performed on the Beaver Valley Power Station (BVPS) Unit 2 Digital Radiation Monitoring System's (DRMS) Communications System.
The work includes upgrades to the DRMS hardware, software and computer peripherals. Components to be upgraded under this planned maintenance include: Redundant Servers, Operator Console, Health Physics Office Console/Workstation, Printers and Portable Mass Storage/Backup and Computer peripherals necessary to interface with the computer system. This planned upgrade on the Unit 2 DRMS Communications System will result in the loss of Unit 2 radiological monitoring capability in the Control Room and on the Plant Computer System (PCS). Neither the Emergency Response Facilities nor the Emergency Response Data System (ERDS) will receive radiological data. No actual radiation monitors are affected. The scheduled work duration is approximately three weeks.
When the DRMS is out of service for the upgrade, compensatory actions will be in place. Radiation monitors will be continuously monitored for any increases in radiation levels. The Unit 2 Shift Manager will be notified of any increase in radiation monitor readings, including exceeding Emergency Action Levels (EAL).
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 upgrade to the DRMS Communications System will result in the loss of the Unit 2 radiological monitoring capability in the Control Room and to the Unit 2 Plant Computer System that affects the functionality of an Emergency Response Facility.
There is no impact on the health and safety of the public or plant personnel.
The NRC Resident Inspector has been notified.
The licensee is currently in a Technical Specification Action Statement, Limiting Condition for Operation for spent fuel pool radiation monitor and leakage rate monitor.
