The independence of the preferred power system with respect to the onsite power system is evaluated. The scope of review extends to the safety- related distribution system buses that are capable of being powered by standby power sources. It does not include the supply breakers of the safety-related distribution system buses. This evaluation will include a review of the electrical protective relaying and breaker control circuits and power supplies to assure that loss of one preferred system circuit will
