en the other hand generally worked out by direct communication, For example, general rad-safe requirements are submitted to the Test Director in status reports but a Project Officer and a head monitor will work out the details ef any specific recovery procedure in accordance with the general AEC rules governing radiological safety. Staff and Advisory Sections The two major Staff Sections are the Engineering & Construction Section and the Plans & Operations Section. The first is charged with the responsibility of | coordinating construction of all test installations, with the maintenance of a current instrument chart, and with processing of job orders originating in the Test Director's Branch. In the planning phases of an Operation the Engineering & Construction Section coordinates the layout of instrumentation at the Proving Grounds, assists the Project Officers in formulating design criteria for recording shelters and instrument stations, passes design sketches to the AEC Field Manager for the preparation of working drawings, obtains approval of these drawings from the Project Officers, and authorizes for the Test Director the construction of required facilities. During the construction phases this Sec- tion assists the Field Manager in the programming of the work and in the in- spection and acceptance of completed facilities. During the operational phases the Section assists Project Officers in obtaining additional minor facilities, emergency repairs, etc. through the processing of job orders, The Plans & Operations Section is charged with the responsibility for coordi- nation of all test operations. This Section arranges for operational transportation, coordinates the use of radio frequencies, schedules recovery parties, etc. While the Engineering & Construction Section is generally most active in the pre-operational phases, the Plans & Operations Section is most active in the operational phases. The other Staff Sections have functions which are somewhat less extensive than ids the case with the corresponding military sections. The Test Director's Personnel Section does not, for example, maintain pay records, These are maintained by parent organizations, civilian or military. Instead the Personnel Section presents to the AEC Field Manager the Test Director's view in matters of housing, messing, the handling ef personal mail and laundry, recreational facilities, etc. pondence, The Section also operates a Mail Room for official corres- The Field Manager handles a large portion of the logistics and supply problems which arise in the Test Organization inasmuch as he furnishes shipping instructions, cartage from railheads, and warehousing and storage at the Nevada Proving Grounds. Most experimental units handle their supply problems internally, and the Test Director's Logistics & Supply Section is in effect an offshoot of the LASL Supply & Property Department set up to serve LASL experimenters. The Test Director has no Security Section as such. Security is a function handled by the AEC Field Manager. The Test Director has, however, a Classifi-
