Recent testing and subsequent calculations have found the room leakage rate is higher than the leakage rate specified in the 1998 design calculation. As such, more carbon dioxide would be required to meet design requirements. The minimum required level for the system storage tank would not currently provide two shots of carbon dioxide (design requirement) to suppress a fire. "The minimum required quantity in the tank would be sufficient to provide one shot of carbon dioxide to suppress a fire; however, since this doesn't meet the design requirement, a continuous fire watch was initiated." The licensee notified the NRC Resident Inspector. * * * RETRACTION ON 7/16/13 AT 1648 EDT FROM MARK LOOSBROCK TO DONG PARK * * * "Further evaluation determined that the as-found configuration did not meet the minimum design requirements.

This event had no impact on public health and safety. "During work to replace a timer associated with an RN (Nuclear Service Water) level circuit, electrical adapters and jumpers were installed incorrectly, resulting in generation of an Emergency Low Pit Level signal. This resulted in an unplanned actuation for RN to realign its suction source from Lake Wylie (normal source) to the alternate source, the SNSWP (Standby Nuclear Service Water Pond). On 5/28/13, with both units at 100% power, a lo-lo level signal was received for A Train RN Pit, initiating the realignment to the SNSWP for both A and B trains. Prior to this event, both trains of RN were aligned to the SNSWP for maintenance. "The lo-lo level signal did initiate a start of all available RN Pumps. Associated valves, including RN crossover valve, return header isolation valves and non-essential header isolation valves closed as expected. This separated RN trains A and B. This was a complete actuation for Train A and the system performed as designed for existing plant conditions. This event was entered into the site corrective action program for resolution."
