In this case the vault may not remain intact and may not perform its safety function. WSRC will evaluate this condition. Therefore, DG load sequencing and voltage regulations are to be re-tested. Fire detection and alarms systems include heat detectors, smoke detectors, infrared and line detection by thermistor cable. The fire protection system is deficient in many areas, as indicated in various audits and independent reviews.
Implementation is divided into two stages.
Stage 1 consists of design modification and implementation required before radioactive startup, and Stage 2 consists of modifications not required before radioactive startup. Technical review could not be performed due to lack of documents-for cable sizing and motor design and electric circuit breakers. Halon versus water in the control room. WSRC intends to provide water sprinkler systems in lieu of Halon systems in severa1 areas containing electrical equipment, including the central control room. The staff is concerned that water intrusion into electrical panels could result in electrical shorts and spurious operations, thereby making it difficult to control the plant from remote control panels.
