electricity. A atomic reactor produces heat through atomic

fission in which atomic muclei interrupt apart let go ofing big sums

of energy. In the nucleus of the reactor, a self-sustaining

atomic reaction takes topographic point.

The power degree of an operating reactor is monitored by a assortment

of thermic, flow, and atomic instruments. Power end product is controlled

by infixing or taking from the nucleus a group of netron-absorbing control

rods. The place of these rods determines the power degree at which

the concatenation reaction is merely self-sustaining.

In the pressurized H2O reactor, the H2O collant operates at a force per unit area

150 ambiances. It is pumped through the reactor nucleus, where it is heated

to about 620oF. The superheated H2O is pumped through a steam generator

where, through heat money changers, a secondary cringle of H2O is heated and

converted to steam. The steam drives turbine generators, is condensed back to

H2O, and pumped back to th

vitamin E steam generator. The secondary cringle is isolated

from the reactor nucleus H2O and, hence is non radioactive. A 3rd watercourse of

H2O from a chilling tower is used to distill the steam. The reactor

force per unit area vass are 49 pess high and 16.4 pess in diameter, with walls 10 in.

thick.The nucleus houses some 82 metric dozenss of uranium oxide contained in the

corrosion-resistant tubings. Finally generators produce electricity which is

delivered to a power grid by transmittal lines.

During operation, and even after shutdown, this big 1000 megawatt power reactor

contains one million millions of Cis of radiation. Radiation emitted from the reactor

during operation and from the fission merchandises after closure is absorbed in midst

concrete shields around the reactor and primary collant system. Other safety

characteristics include exigency nucleus colling systems to forestall nucleus overheating in the

event of malfunction of the chief collant system and, a big steel and concrete

containment edifice to retain any radioactive elements that might get away in the

even of a leak.
