E. Safety Analysis
The ESCW cooling capacity for each train is sized for 100 percent of the plant safety HVAC system cooling demand. This ensures that with the 'A' train of ESCW operable, the site would still be within the analyzed results for all transient and accident conditions, particularly as documented within the HNP Final Safety Analysis Report Chapter 6 and Chapter 15.
No loss of safety function occurred as a result of this event. At no point during the impacted periods was the ESCW system required to mitigate the impact of a design basis event. As such, this event had no significance with respect to the health and safety of the public.
F. Additional Information
The events leading to the WC-2B trip are unique to this event. There have been no LERs submitted in the past three years due to a similar event.
