The Weapons Inspection Activity Inspection personnel utilized in the field office inspection program initiated April 1, 1950, were military officers and enlisted men assigned by AFSWP. Prior to the AEC in-- spection activity, they served as AFSWP inspectors to assure that military requirements were met in products processed and delivered by Sandia Corporation. Subsequent to July 1950, civilian personnel were hired and trained to replace military inspectors; replace- ment being completed in June 1951. Concurrently, a liaison section was formed by Field Command to assist in inspection problems. A site reacceptance inspection program was activated in September 1950. AFSWP with field office approval designated military officers at Sites Able, Baker, and Charlie to serve as AEC Chief and Alternate Chief Inspectors in ZI site reacceptance of bombs which had been temporarily released from AEC custody for the purpose of functional surveillance inspection by Sandia Corporation. In September 1951, AEC reacceptance inspection was similarly initiated at Site Dog. In the period July-September 1952, AEC inspection at Sites Easy, Fox, and George was instituted subsequent to agreements between AEC-SFOO and AMC. Similarly, inspec- tion at Site How was initiated in April 1953. Inspection at Site Jig was initiated in July 1953, after agreements were reached between AEC-SFO and Navy-BuOrd. Each site AEC inspection office has a chief and an alternate chief inspector responsible to Sandia Field Office on all matters pertaining to AEC reacceptance activities. AEC-SFOO formulates policy and issues appropriate directives setting forth broad responsibilities of the inspectors. AEC site inspectors are drawn from the local military command for periods wherein plant operations are performed on AEC materiel. Site inspection groups vary in size depending upon capacity of facilities and equipment and extent of plant operations; ranging from approximately 15 inspectors at Sites Able and Baker to approximately 8 at Site Easy. The AEC inspection programs, within the field office and at the ZI sites, have been directed toward a final product acceptance concept. In addition to 100 per cent acceptance inspection of delivered materiel, monitoring of receiving and process inspection performed by the contractor is achieved by means of "sampling checks" of material and review of contractor methods, facilities and equipment. In 1952, a resident AEC inspector was established at Douglas Aircraft in El Segundo, California, to accomplish AEC acceptance inspection on mechanical components processed for Inyokern and Sandia. This joint AEC-Sandia Corporation inspection activity at vendor eliminated need for shipment to Sandia prior to delivery to Inyokern and improved delivery dates for stockpile. Expiration of Douglas contracts with Sandia will allow recall of this inspector in December 1953. It was felt that considerable savings might be realized by performing AEC inspection at Motorola in Chicago with subsequent direct delivery of radars to stockpile. Consequently a resident AEC inspector was established on a trial basis in May 1952. Technical analysis of radars produced during the period May-August 1952 indicated, however, that reinspection utilizing Sandia facilities was still required; the resident inspector was therefore recalled. Appreciable savings were realized in accomplishing AEC inspection at Picatinny. An AEC-Sandia inspector made frequent trips to Picatinny to inspect the Mark 9 shells 18 DOEJAln ee x3
