The laboratory then presents the full containment plan to the Containment Evaluation Panel (CEP) 2 to 3 months in advance of the detonation. The CEP is a panel of experts that review and evaluate the containment plan for each test.2? Each CEP panel member goes on record with a statement concerming his judgmentof the containment. The CEP chairman summarizes the likelihood of containment and gives his recommendation to the manager of Nevada Operations. Following the CEP meeting, a Detonation Authority Request (DAR) package is prepared. The DARpackage contains a description of the proposed test, the containment plan, the recommendations of the CEP, the chairman's statement, a review of the environmental impact, a nuclear safety study.< review of compliance with the TTBT. the public announcementplans, and any noteworthy aspects o! the test. The DAR packageis sent to the DOE Office of Military Application for approval. Although tes preparations are underway throughout the approva process, no irreversible action to conduct the test i: takenprior to final approval. After the test has been approved. the Test Grouy Director of the sponsoring Laboratory will ther request ‘‘authority to move, emplace. and stem’ the nuclear device from the Nevada test site **Tes Conwoller’’ for that specific test. The Test Control ler also has an advisory pane! consisting of j Chairman and three other members. The Chairmai (called the Scientific Advisor) is a semor scientis 22See Ch. 3, ‘Containment Evaluauon Panel.” 23The nuclear safety study prepared by DOE Safety Division contains safety considerauions not related to containment, such as the possibilty ¢ premature or inadvertent detonation. *4In the case of tests sponsored by the Defense Nuclear Agency (DNA), the Scientific Advisoris from Sandia National Laboratory
