from its capacity on the previous performance test, or is below 90% of manufacturer's rating. Provide assurance that the current definition for battery degradation being usedat BVPS-2 provides an accurate indication of each battery's condition.3.Provide assurance that the BVPS-2 UFSAR will reflect the proposed designchange. 4.Provide an updated electrical one-line diagram that shows the proposed designconfiguration.5.How will you prevent the rectifier assemblies from providing direct current i nputto the respective 125-volt direct current bus?
