hs SECTIONVII OPERATION BETWEEN EXPERIMENTS OPERATIONS INVOLVED: General. The period referred to as Phase V of the construction program will be defined as the roll-up. It will begin with the conclusion of a test- ing program, includes securing the area, ani extends through the period of quiescense as necessary. It covers such items as these: Salvage Storage Demobilization Maintenance Protection of structures and utilities Resident maintenance personnel Security and radio safety Issue completion report Roll-up Preparation. The operations immediately prior to the detonation of a bomb is conceived in this Report to involve the salvage of a maximum amount of valuable facilities which are subject to damage or destruction by bomb effects, providing that such salvage can be practically accomplished without interfering with installation and other work at the forward area, and providing that the removal of any such salvage can be accomplished in a period up to twenty-four hours prior to bomb detonation. Practicability of the elements of this salvage are discussed in Section IV under various headings in the analysis of probelms of design. It is recommended that adequate storage facilities be provided on Parry Island for the roll-up period, it being felt that any items remaining on shot islands, if subjected to open storage amd idleness throughout this rollup period will suffer such deterioration that dependability for future use would be in question. Maximum mobility is being considered for mechanical units involving a high capital outlay on the shot islands, and maximum proVII +1
