_Sampling System._ This system provides a means for removing liquid
samples from the primary loop to determine the effectiveness of the
purification system. Samples will be taken from both the inlet and
outlet flow of the primary demineralizers.
_Intermediate Cooling System._ The primary function is to provide clean
cooling water to the various reactor system components. A secondary
function is to maintain water in the annular primary shield tank.
The system consists of two separate flow circuits: a sea water circuit
and a fresh water circuit. Each of these circuits contains two pumps and
two coolers, plus other necessary components. The pumps and coolers are
arranged in parallel, permitting either pump to supply water to either
cooler.
In the sea water circuit, inlet temperature is 85° F and outlet
temperature is 106° F. The fresh water enters its coolers at 143° F and
leaves at 95° F.
Components outside and inside of the containment vessel are cooled by
one or the other of these intermediate cooling circuits.
