Power plant liquid wastes are collected in tanks for storage prior to
discharge into a specially designed servicing vessel in port. The liquid
waste collection tanks are monitored. Gaseous wastes will normally be
disposed of at sea through the radio mast, which contains two detectors
for monitoring purposes. They are an air-particle monitor and a
radio-gas monitor, and operate at all times so that gas is vented to the
atmosphere. If gaseous radioactivity should rise above specified limits,
the gas will be diluted to below the limit before being discharged to
atmosphere.
The above monitor stations are the principal ones involved in reactor
system operation. The monitors operate through a system of separate
channels, with each channel responsible for a pre-selected range of
activity. All detectors relay their readings to the main panel in the
control room, where automatic recording and visual observation
instruments are located.
