~A M & R REcords Center "635-Eniwetok Proving Ground" Folder A 6 March 1958 TWX from Starbird to Bradbury,Street of Livermore and Reeves asks for their opinions of a couple possible options for future test series. One would be to keep the . Eniwetok Proving Ground open continuously after Hardtack with very few shots of small yield being done periodically at the NTS and with these being done underground as far as diagnostics would permit. A second alternative to be thought of would be somewhat the opposite and that would be to utilize Eniwetok only every so often like every 2 years to fire all those shots over some designated yield such as 500 kilotons or that could not for diagnostics or effects reasons be fired underground at the NTS. Under this latter plan a continuous type operation would be established at the NTS using the underground technique for the great majority of shots and authorizing an above ground shot only on an individual basis and not to exceed the present limitations. The Livermore answer to this hostile TWX from Kenneth Street on 10 March was persis(In favor of going to a continuous testing concept. Furthermore, that laboratory favored the first proposal to have the Eniwetok Proving Ground open on a continuous basis over the NTS continuous operation. Bradbury's answer for LASL on tl March also favored the new proposals for nex more continuous testing although it was somewhat less enthusiastic and In part he states "It would seem preferable to consider more frequent or continuous testing at-Entwetok with periodic operations at Nevada rather than the reverse arrangement." Bradbury goes on to cite some of the problems with the . continuous administration of Eniwetok and In that vain asks that perhaps consideration should be given to operating Eniwetok on perlodic basis but at yearly intervals and this might provide manyyof the benefits to be expected from a continuous operation without the headaches which such By 7 7 T
