From page 15...
... Therefore, it is necessary to decide how much of the maximum permissible intake shall be allocated to the results of waste disposal from nuclear-powered ships. Since the maximum permissible concentrations so determined apply only to that activity originating from nuclear ship operation, they are actually partial permissible concentrations (ppc's)

... Thus only a portion of the total potential receiving capacity of these waters is available for waste disposal from nuclear-powered ships.

... It is further assumed that 30 percent of the maximum permissible dose which this population may receive as a result of sea disposal may be allotted to waste disposal operations from nuclear ships in these waters.

... Further, for each of the subdivisions of the marine environment, designate by Np that fraction of the protein requirement which a selected portion of the population receives from seafood harvested there; designate by N[> that fraction of the maximum permissible dose for this population which can be allotted to waste disposal into the sea, and by Ns that fraction of the allotment to the sea which may be utilized for nuclear-powered ships within the particular marine subdivision. Then the partial permissible concentration in seafood which can result from the operation of nuclear-powered ships, for each of the subdivisions of the marine environment, is obtained by multiplying the maximum permissible concentration for drinking water for the general public by the factor Nm, which is given by 19
