aaa 3-28 Island, ar: ..aluation was made of the capabilities to support both operations with personnel and eq:ipment from resources available in the EPG. In ad~- dition, an allout effort was directed towards the dismantling of the launch tower and other APYA facilities on Bikini Island for shipment to Johnston Island prior to the first large UCRL shot, Prolonged bad weather delaved this first shot and the island was evacuated completely without difficult. Johnston Island operations will be discussed in Section 3.7.8. Experience in the evacuation of Bikini Atoll gained from previous operations was put to good use during this operation. The evacuations cone ducted for the atoll were all accomplished with no serious delays, The TG 7.1 J-3 Section oublished Operational Letters for each shot as follows: Prediction of Effects and Operational Planning Factors. Ready Date and Shot Times. 7 Evacuation and Re-entry Check List. Organization anc Movement of the Arming Team, In addition, many of the early events which had heavy participation by the scientific projects required operational letters outlining the scientific frequency allocation and the plan for the movement and positioning of the device from the weapons compound to the zero site area. It was originally intended th2t the calculations for blast and therma_ effects woild be performed by a staff section of JTF SEVEN (FOPU). However, the Fallout PredictionUnit of JTF SEVEN did not arrive in the area until approximately 10 April and became operational several days after that date. In view of the early planned ready dates for some of the shots it was ne- cessary th-t computations be performed for Teak, Orange, and other planned early events, These computations were performed by the J-~3 Section. After FOPU became operational, assistance in determining blast and thermal data for several shots was provided the J=-3 Section but for the most part it , ,oyEp/DOE LANL RG” wae a case of verification of the compilation of predictions. !
