We need to knew that all of the energy has been properly accounted for in the analyses and that the analyses naYe Considered the Worst Case break and conditions of heat transfer. We cannot evaluate the validity of the applicants' conclusions at this tim en the basis of the infomatica and analyses that have been presented.

hign specifications for the containment vents and purge valves ara needed in the FSAR along with tests or analyses vhich ensure proper operation of these valves.
We need a discussion of the provisiens for rnonitoring hydrogen in the reactor building atmospnere.
Systems or portions of systems which will be open or vented to atms-phere and/or drained of fluids, as required by 10 CFR 50, Appendix J, need to be identified. Exceptions must be identified and Justified.
Leak testing requirinents and compliance with Appendix J,13 CFR 50 were discussed.
For-al questions will be submitted to the acplicants en all items of discussicn where a response is needed in. the FS'R.
