ENCLOSURE 2 ADDITIONAL NRC QUESTIONS ON THE V. C. SUMf1ER SERVICE WATER INTAKE STRUCTURE 1.

Evaluate the existing structure to determine safety margin a;sinst NRC SRP 3.8.4.

2.

If there were longitudinal separation and transverse relative displacement, evaluate the functionability of existing structure, with a conservative a'sumption on the extent of through structure cracking.

3.

Describe'the engineering evaluation criteria of the existing structure in

'the: longitudinal direction. Such criteria should be given in terms of quantative values of stress,' strain, force or deflections. Justify why such criteria are adequate for seismic load.

Provide any examples where such criteria have been used (ASf1E, ACI, AISC etc.) possibly in nuclear

' plant design.

4.

Describe the action that would be taken if the acceptance criteria were to be exceeded (settlement monitoring).

5.

If there were through thickness cracks, determine the differential hydro-static pressure between inside and outside the structure with pumps in operation.
