A [4 April TWX from Stewart of OMA to the labs etc. addresses the upcoming brieting for the President's Scientific Advisory Committee. Subject of the briefing is current plans for possible resumption of testing. There follows lists of devices to be tested at NTS and also to be tested either at the EPG or over open seas. He requests LASL and Livermore comments as well as response times for the various tests that might be more than 90 days away. A TWX from Bradbury to John McCone, AEC Chairman on C [5 April addresses the question of laboratory morale and discusses where some of the {fabor- atory effort might be redirected during the moratorium. (Criticizes present uncertainty and states positive decision even for programs other than testing would be better.) Documentation in this time period addresses the terms of the Geneva neqo- tiations, definitions cf various prepcsals being put forth there and notes and discusses some of the questions of cevection of various levels of nuclear detonations underground. On 15 April, 1959, Bob Newman wrote a letter to Jim Reeves on “eltermate full Sewer - - sale underground shot locations and facilities." The proposal is for four sites £ two types (tunnels and holes) of containment facilities on RAINIER Mesa within wo miles of past Livermore shots, if Area 3 is proclaimed tandpoint of ground water contamination. to be unsafe from the Newman says that the Mesa is believed 3 be the only presently developed and/or available area within the NTS which eets all criteria. The proposal is for four snot points at a two thousand foot pacing for tunnel portals or four shot points at 1500 feet spacing for vertical oles with a minimum cover of 1000 feet, known media, no contamination permissible n ground water at producing water wells, and tilities as well as reasanable access. reasonably near existing roads and He goes into the details of locations of he tunnels and noles proposed with an accompaning map as well as specific roblems in access, power provision, telephone lines, etc. Only ALPHA measurements ave been taken into account in the design in a preliminary way of these facilities nd further diagnostics would have a significant impact. A rough estimate of the ost for developing the four tunnels is 57,000,00 and for the four holes is 3,000, OOO. He emphasizes, above all, that LASL prefers to operate in AREA 3 ‘ause Of the ease and economy of construction and operations and the readily lable facilities, roads, etc. Finally, he requests that design, necessary site idies, and cost studies be initiated immediately for the tunnels and holes on -NIER.
