- SF FIEST 955f105 List FOR BAE7DED 30. 2, DOMET 30 50-397 S e first Ennstre Es. t geestion list esters most of the topies in the PEAR emosyt for conduct of operations, alte meteorolgieel and radio-logical sharacteristies and a sow other miscellaneous topics. A second question list will be issued to cover these topics.

i The questions in the first list are mostly routine is nature and are directed toward obtaining infomation missing fmm the PEAR, except as noted below.

1.

Gnaestion 515 concerns itself with clearance between the contaisament and the ococrete shielding since this is the first over-under containment designed as an AaBE steel Pressure Yessel.

2.

Question 8.1 is unique to Eanford No. 2 boomuse WPPSS I

neither owns or controls the Electrical Switehyard or the Power Tran==1selon Lines. Bonnyville Power Ad-ministration (EPA) controls them. In addition, EPA has the right to interrupt or reduce off-site power to Banford No. 2 in oase of emergencies or to make repairs and do maintenance.

3 Ghaestion 913 requested additional data en the perfomance I

of the radioactive gas system since WFPBS indicate they C

intend to operate the system at O F.

4.

(mestion 10.1 concerns the adequacy of the two spray ponds (ultimate heat sink) for providing at least 30 days cooling capability. Bro spray water pedds are pr4vided.

.'3 13 CZ Roger S. Boyd Each spray pond contains 7 days of water storage if make up water, designed to Seismic Class II, criteria, is lost.

Estal water storage is both spray pomos is saffisiest for 30 days cooling espability. Esseuer, if single failure eriteriu tr man ende structures is applied to the design

- only 7 days ecoling especity eam he somsidered available.

l 5

Gaestions 12.17 and 12.18 sommeras eriteria for pipe i

whip protection. This will be a major problem area since it is doubtful that pipe restraints saa be anchored j

to the steel containment vessel.

l 6.

In @aestion 14 5 we require the installation of a seal j

system to minimize main steam line isolation valve leaka6e-7 In Saestion C-2 we have requested more information on the main steam line piping seismic design from the outermost i

containment isolation valve up to turbine casin6-These comprise the non-routine areas of the first question list.

i Please note in Item 6 (%nestion 14 5) we have indicated that we require the installation of a seal system. No management action on any of these items is requested at this time.
