1. PURPOSE This planning directive provides guidance and basic information concerning the AECIDOD readiness program for possible resumption of full-scale testing in the Pacific area. Even though this planning directive is primarily concerned with the conduct of Nevada Operations Office support activities, pertinent DASA Readiness Program concepts are also presented so that NVOO/DASA interfaces and authorities can be defined. It can be used as a primary source document relative to major agreements, organizations, responsibilities, AEC/DOD interfaces, etc. 11. INTRODUCTION A. Responsibilities Under Test Ban Treaty. Under the safeguards established at the time the Nuclear Test Ban Treaty was signed in 1963, provision was made for... “The maintenance of the facilities and resources necessary to institute promptly nuclear tests in the atmosphere should the treaty or any of its terms be abrogated by the Soviet Union. ..” This responsibility has been jointly shared by the AEC and DOD. Under this AEC/DOD responsibility, the continuing mission of the NVOO is to maintain the capability to support AEC/DOD test readiness in accordance with the National Nuclear Test Readiness These Program, AECIDOD agreements, and other policy directives. NVOO responsibilities lie generally within the areas of engineering and construction, facilities maintenance and operation, technical support to AEC Laboratory programs, and off-site public safety. Scope of work statements and assignments or responsibility within these areas as described in succeeding parts of this document, follking an introductory section on background and current status of the program. B. Earlier Development of Readiness Capability. A readiness capability associated with airdrop technique and some missile launches was achieved in 1965 and subsequently maintained and exercised on a “GO + 2 months” basis. Since that time, changes and developments in the objectives of the AECIDOD Reau]ness Program have established the requirement for a revised readiness capability associated with high-altitude detonations of nuclear devices. The revised program established in the National Nuclear Test Readiness Program (NNTRP) document of October 1968 reflected a change in emphasis from airdrop atmospheric tests to high-altitude tests of nuclear warheads for ABM and other applications. -5-
