(a) If either ship (presumably Able) is judged by the Radiological Safety Advisor and the Project Officer to be safe for continued occupancy, her operating party will board her and take over manual contrel. Reboarding will be accomplished underway. (bo) If either ship is judged to be safe for only limited occupancy, MOLALA will continue radio navigational control and the operat- ing crew will board for a short period of time (commensurate with the radiological situation) in order to resume manual engineering control. When manual engineering control is resumed, the operating crew will debark to its respective ATF, leaving the ship to steam unattended for a short period of time. Depending upon the radiological situation, the crew will reboard at intervals to maintain a watch on the engineering controls. (c) If it is determined by the initial radiological survey that it is unsafe toreboard a ship, her engineering spaces will be secured by securing the main feed valve and the main fuel pumps at the external controls provided and the appropriate ATF will take the ship in tow. will be accomplished without boarding the ship, the tug picking up a pendant rigged on the bow of the ship. This ‘Then the ships have been recovered and/or are under control of the ATFs, the P2V5 will ireturn to Kwejelein. 504.4 Movement of Ships to Eniwetok Immediately upon resumption of local or ATF control, Able and Baker will proceed toward Iniwetok. Continued radiological surveys of the ships will be conducted underway. As soon as either temporary or permanent occupancy can be granted, to the ship(s) in (b) and (c), paragraph 5.4.3, this will be carried out - toward the end of increasing the speed of the ship. Under tow, it is anticipated that a speed of 4 knots can be made under continuous or semi-continuous engineering watch, full speed, 10 knots, can be maintained. This will mean a time of return of approximately 45 hours or 18 hours respectively. ST. LOUIS FRC 5.4.5 Determination of R-Hour and Other Radiological Safety Data Data from the radiological surveys conducted underway will be relayed to the Project Officer who will have returned to Eniwetok with the other P2V5 personnel from Kwajalein. Based on the observed rate of decay of the activity, the intensities observed by the Radiological Safety Advisor, and the telemetered data from the P2V5, the intensities will be extrapolated forward to determine at what time intensities will reach or be below 2.5 r/hr. If either ship is running under continuous manual con- trol by the operating party, R-hour will be the time of arrival of the ship at Eniwetok., At this same time, the Radiological Safety Advisor will install, where possible, air-monitoring devices and will transmit any data collected tothe Project Officer on Parry, along with recommendations 009522 , Cilitsin 21 Qe”
