Task I.G.1 Training Requirements (NUREG-0660)

Position:

Licensees will (1) define training prior to loading fuel and (2) conduct training prior to full power operation.

Response

A set of low power tests to be performed will be identified three month's prior to fuel load. However, since Seabrook has a site specific simulator which is maintained current with Unit 1 design as per ANSI /ANS 3.5-1979, each operating crew will perform the designated low power tests on the simulator. Therefore, only the crew on shift need perform the low power testing on the actual plant.

Task II.B.1 Reactor Coolant System Vents (NUREG-0737)

Position:

Each applicant and licensee shall install Reactor Coolant System (RCS) and reactor vessel head high point vents, remotely operated from the control room. Although the purpose of the system is to vent noncondensible gases from the RCS which may inhibit core cooling during natural circulation, the vents must not lead to an unacceptable increase in the probability of a Loss-Of-Coolant Accident (LOCA) or a challenge to containment integrity. Since these vents form a part of the reactor coolant pressure boundary, the design of the vents shall conform to the requirements of Appendix A to 10 CFR, Part 50, " General Design Criteria". The vent system shall be designed with sufficient redundancy that assures .s low probability of inadvertent or irreversible actuation.

Each licensee shall provide the following information concerning the design and operation of the high point vent system.

(1) Submit a description of the design, location size, and power supply for the vent system along with the results of analyses for loss-of-coolant accidents initiated by a break in the vent pipe. The results of the analyses should demonstrate compliance with the acceptance criteria of 10 CFR 50.46.
