Sere 3, Fallout Hazard. Any of the three approaches will reduce the expected fallout to some degree under that of the earlier presented plan for PILGRIM. Plan I, of course, would remove possibility of fallout around NTS. Plan II would assure that off-site fallout on any community around NTS would be limited to a low level and that the operation could be conducted with relatively few long delays. Plan III could be nearly as effective as Plan II in limiting the fallout. It is believed ‘that either Plan II or Plan III could be carried out with almost certainty of success and without prohibitive delays under the "10 R in 10 year criteria." For neither II or III could such assurance be given for a value of "5", or "6 R in 10 years." 4, Effect on Weapons Development Schedules. Adoption of Plan I would have a very unfavorable impact on the AEC and the DOD with respect to weapons readiness and development schedules, and moraleof personnel. of HARDTACK, It would delay materially completion Plan II could be adopted with some undesirable effect on the weapons program. somewhat. It would prolong HARDTACK Plan III would have little effect on weapons readiness schedules, and would not delay or prolong Operation HARDTACK, 5. With respect to AEC funding, Plan I would probably not require additional FY 1957 or FY 1958 funds, but would add some $10 million to FY 1959 test costs because the 1957 Pacific Operation would push Operation HARDTACK farther into FY 1959, Plan II would require some $10 million additional funding authority in FY 1957. Pian III would result in relatively minor adjustments in expenditure of funds. 6. Effect on DOD Effects Programs. Plan I would have a very detrimental effect on the DOD and Civilian Defense effects ~-2. 12
