Atomic qbate ¥-2a 2 {oc So?SECRET SECURITY INFORMATION ATOMIC ENERGY COMMISSION 13 October 1952 SUMMARY OF LOS ALAMOS SCIENTIFIC LABORATORY FULL-SCALE NUCLEAR TEST PROGRAMS Full-scale tests of nuclear detonations are essential to the program of atomic weapon development for the following reasons: 1. Actual test of a nuclear weapon or warhead before it enters the national stockpile. 2. To demonstrate the adequacy (or inadequacy) 3. To explore phenomena which can vitally of current theoretical approaches in order that promising avenues of development may be more fully exploited or given lower priority of attenticn. affect the efficiency of an atomic weapon but which are not susceptible to prior theoretical analysis of sufficient certainty. 4, To choose between existing theoretical methods of weapon improvement the attack of greatest practical significance. ) It is not possible to do more than highlight the significant results of each full-scale nuclear test in the past. Most such programs are interdependent and interrelated. Ina large majority of the cases they provide further confirmation of the adequacy of theoretical approaches and predictions; occasionally they indicate further problems to be solved in order to maximize the utilization of active material in a given set of circumstances, In retrospect,' some tests now seem obvious; at the time they were striking new exploraticns into the frontier of nuclear weapons, ——RESTRECTER—DAPA— This document contains restricted data as defined in the Atomic Energy Act of 1946.
