Question 430.9 In ESAR section 1.9, you state that the design of the fuel oil storage and transfer system conforms to the requirements of Regulatory Guide 1.137, which endorses ANSI N-195.

-< However, there is no reference to testing of fuel oil as discussed in

, Appendix B of ANSI N-195 and position C2 of Regulatory Guide 1.137. Revise your ESAR to include a discussion of your conformance to these requirements.

O Response VEGP conformance to Regulatory Guide 1.137 is addressed in subsection 1.9.137. VEGP does not conform to the requirements of ANST N195-1976. Annandiv R fg :The t : ting requircm:nt; cf ANC!-

VEGP-ESAR-Q Question 430.11 Describe your design provisions made to protect the fuel oil s torage tank fill line from damage by tornado missiles.

Response

The 4-in. fill line for the fuel oil storage tank extends approximately 5 in. from the outside wall surface of the valve O house and is approximately 48 in. above grade.

tornado missile protection for the fill line.

There is no In the unlikely event that the fill line outside the valve house is damaged, the storage tank can be filled by opening the manway cover on the storage tank which is located in the missile-protected pump house. Since damage of the storage tank fill line does not preclude the addition of fuel oil into the storage tank via alternate means, there is no tornado missile protection for the fill lines.

The manway or manhole is shown in figure 9.5.4-1 of the FSAR. 13 The 24-in. diameter manway has a gasketed steel plate cover bolted to the manway flanged opening. A davit is furnished with

() the fuel oil storage tank and is attached to the manway cover for ease of opening and closing of the cover. The manway can be removed by two people. The manway is located on top of the storage tank inside the diesel fuel oil transfer pump room which is easily accessible through the valve room located between the train A and train B pump rooms. Entrance to the-valve room is through a doorway located at grade elevation. Figure 430.11-1

-is a.. plan. and_. sectional _ views ~of the .dieseLfueL oil _ storage.___ _

tank pump house.

The manway is readily accessible and can be removed by two

. people. The diesel generator system operating procedure will outline the steps necessary to fill,the storage tank using the ,

manway.

C:/

In the case of prolonged diesel generator operation, VEGP will make provisions by the 5th. day of diesel operation for delivery

, of fuel oil to the plant site. With a required seven day fuel (br oil supply maintained on site and by making-delivery provisions Ci. by day 5, an adequate supply of fuel oil for the emergency diesel generator is assured.
