Schedule _

The schedule given is for four Uc believe the optimum schedule would be 52 months.(4) years.

Sinco the cuotomer has not issued Section: 2.0 through 6.0 t

of his deaign criteria, it in not poscible for us to consent on his requirements concerning scope of supply and data that he wishes in a propocal.

Our scope of supply for a Huclear Steam Supply System would include the reactor and heat transfer loops with interconnecting piping, and also the nucienr auxiliary systems.

Thece systems 5:ould include the make up and purification system, the chemical addition and samplinc system, the interacdiate cooling system, the spent fuel and shutdown cooling system uith instrumenta

'j We' and control furnished for all equipment in our scope of supply.

would furnish the vaste disposal system if the Customer so desires, f

The aur.iliary systems in our Nuclear Steam Supply Systcc include l

components which are used as parts of an intecrated engineered J

safeguards system.

The Customer should specify Whether or not he j

vants the Nuclear Steam Supply bidder t'o furnish the reactor build cooling cystem which also serves as part o (containment structuro)ds. In our proposal we will furnich design 1

the enginecred safeguar

,)

data for our scope of supply, and we will furnish decicn criteria for that balance of plant furnished by the Purchaser which affects

'i cur equipment.

The only major equipment we would furnish for the cocondary system is the feedvater control system, which is integraB l

5 uith our once-through boiler controls.

l t

The major item of plant equipment that chould be defined by l

4 the Customer's specifications is what part, if any, of the computeg

,t is to be supplied by the Nuclear Steam Supply System contractor.

We can quote the computer to collect reactor operating data and to l

F calculate reactor performance, which is neccccary to any fuel offcg Mc are cico prepared to offer a plant computer to collect oporatini j

data from the entire plant and to, calculate plant performance.

We]

are also prepared to offer the turbine generator portion of the

.tq control system in addition to the stcom Ecnerator control system, which is part of our package.

We would request that the Customer

5j speciP/ what he requires in the bane instrument and control bid and in the base computer bid, and to state optional additions to ai such a base.
