Description

When the malfunctioning transformer T3 at Krsko NPP caused the loss of second independent off-site power source, the plant's Technical Specification required its repairment in 72 hours or the plant would be brought to hot shutdown (cold shutdown after 108 hours). Because it was not possible to repair the transformer on time, the Krsko NPP asked for the temporary change of Technical Specification based on several improvements which could be accomplished in a fairly short time period. The probabilistic study was performed to calculate relative effectiveness of the improvements. (author). 5 figs, 3 tabs
