| ENS 54968 | Wolf Creek | 27 October 2020 21:08:00 | Loss of Emergency Plan Dose Assessment Capability | At 1608 CDT on 10/27/2020, Wolf Creek Unit 1, operating at 100 percent rated thermal power in Mode-1, experienced a loss of the on-site wired corporate network. During actions to restore, it was discovered the ability to access the dose assessment software was compromised due to a security program. Access to the program was established after some time using Wi-Fi connectivity, but was not able to be accessed without network access. Actions are being taken to rectify.
The NRC Resident Inspector has been notified.
The licensee believes this was not a cyber-event and that the Emergency Response Data System was available, but couldn't verify. Should the Wi-Fi network access be lost, there's no capability to perform a dose assessment. Standalone laptops are being provided but have not been placed onsite yet. That should restore the ability to have dose assessment capability at all times.
- * * UPDATE ON 10/27/2020 AT 2220 FROM JOHN WEBER TO OSSY FONT * * *
The licensee notified the NRC that the network has been restored to the Technical Support Center building and the emergency plan dose assessment group was capable of performing dose assessment. The licensee also noted that the group is able to perform dose assessment without the network, if needed. The network is still unavailable in the control room. The licensee confirmed that ERDS is available.
The licensee will notify the NRC Resident Inspector.
