15 people and to supply an emergency shower located at the access door
between the Primary System Water Service Area and the Auxiliary Equip-
ment Area. The location of the domestic supply tank in the basement of the
control building assures a supply of water for personnel detained within
that building for any extended period of time because of a contaminating
2. Primary Water Make-up System
The primary water make-up system is designed to replace
the water removed either intentionally or accidentally from the primary -
system. It consists of a demineralizer, a primary water make-up tank and -
primary system make-up pumps. The first item will be located in the Aux-
iliary Equipment Area; the latter two will be located in the Primary System
Water Service Area. The demineralizer is supplied from the treated water
storage tank and discharges to the primary water make-up tank. This tank
also acts as collector for the following:
a. After-condenser condensate
b. Recombiner condensate
c. Reactor vessel cover gasket leakage
d. Pump seal leakage
e. Control rod drive seal leakage.
3. Reactor Water Clean-up System
In order to maintain the high water purity required to mini-
mize system contamination from radioactive corrosion products and to re-
move boric acid and other intentionally introduced additives, a primary water
clean-up system is provided.
The primary water clean-up system consists of a regener-
ative heat exchanger, cooler, booster pumps, filter, and ion exchanger. These
items are located in the Primary System Water Service Area. Approximately
25 gpm of circulating water is drawn off for continuous filtering and de-ionizing
to maintain purity of the reactor water. A sufficient quantity of water to main-
tain the required temperature of the control rod thimbles is taken from this
4. De-aeration System
The dissolved gases in the primary water make-up, as well
as gases resulting from water dissociation during reactor operation, are -
removed from the primary system by a continuous flow of vapor and gases
from top of the de-aerating-hotwell. The vapor and dissociation products
are recovered by the de-aeration system, consisting of the after-condenser,
the recombiner, and the dryer. These components are located in the steam
