8. base dispersion calculations on 1 m/sec wind speed, Cy = 0.4,
Cy = 0.07, n = 0.5, h = 0,
9. establish specific emergency plan,
10. test auxiliary boilers in port,
11. maintain vacuum on main condenser,
12. limit ship visitors to one-half the acceptable number,
13. limit site visitors to one-half the acceptable number,
14. conduct evacuation drills regularly on ship and on site,
15. test reactor compartment integrity and emergency system oper-
16. test containment-vessel leakage rate, filter efficiency, and
duct tightness periodically,
17. have senior nuclear staff member aboard ship in port,
18. have health-physics staff member aboard at all times reactor is
19. get approval of port analysis report by regulatory authorities,
20. establish conservative zone boundaries for 25 rem in specified
time (1 hr, 480 ft; 2 hr, 650 ft; 24 hr, 1600 ft),
21. assume instantaneous release of fission products to containment
22. assume maximum number of persons in controlled zone in calculating
total population exposures,
23. do not consider individual exposures of less than 0.05 rem,
24. take no credit for holdup in the reactor compartment.
Since the Reactor Site Criterial were specifically intended to re-
flect stationary-reactor siting practice in the U.S., the criteria not
only did not cover many of the new problems introduced by a mobile reactor
but also would have specifically excluded nuclear ships from most harbors.
As has been previously noted,20'21 the provision that made it impossible
to apply the stationary-reactor criteria to mobile reactors was the stipu-
lated city distance, that is, "at least 1-1/3 times the distance from the
reactor to the outer boundary of the low-population zone." Since the
specified low-population-zone boundary increases from 1.6 miles for a
60-Mw(t) reactor, it is readily apparent that city distances 1 1/3 times
the above would deny a nuclear merchant ship access to most ports in the
world. This being the case, it is important to know what the function
of the city-distance criterion was. As stated in the Reactor Site Cri-
"One basic objective of the criteria is to assure that
the cumulative exposure dose to large numbers of people as a
consequence of any nuclear accident should be low in comparison
with what might be considered reasonable for total population
dose. Further, since accidents of greater potential hazard
than those commonly postulated as representing an upper limit
are conceivable, although highly improbable, it was considered
desirable to provide for protection against excessive exposure
doses to people in large centers, where effective protective
measures might not be feasible."
