The amount of radioactive materials in the primary coolant is maintained at relatively low levels by use of a bypass purification system resulting in the accumulation on ion exchange resins of corrosion product activity, and a considerably smaller amount of fission product activity. The greater part of the fission products is removed from the ship in the spent fuel elements at the time of refueling.

These 300 ships would then potentially release to the marine environment approximately 2500 curies per year from expansion water, some 3400 curies per year from leakage and other minor sources of liquid wastes, and some 9 x 105 curies per year from the ion exchange beds. 'Since completion of this report, subsequent re'evaluation of the probable character and activity of the primary coolant and the ion exchange resins has been issued by the Oak Ridge National Laboratory (1959)

Release of activity to the coastal environment by land based nuclear installations, particularly chemical processing plants, may be difficult to avoid. Thus, under a carefully controlled program designed to limit the return of activity to man to a safe level, the Windscale Works in England is authorized to release over 105 curies per year into the coastal waters of the Irish Sea.
