-15worked on with attention being given to equipment and techniques for certain unique problems, such as line of sight holes, drilling into regions of elevated temperatures and pressures, drilling of shaped holes, and drilling into radioactive regions. Also being studied are containment problems and in particular a plan is being made for a proposal of an HE containment shot in granite. Note that the status of Plowshare still had Gnome being planned to occur in Aug. of 61. As near as I can tell in this 31 page report, no mention is made of the 410 activities. An update of the Livermore programs is presented in a letter from Foster to Betts on 24 Aug. 61, 6£ the devices mentioned, only one! i awaiting resumption of nuclear testing." "is now on the shelf This is interesting in light of the discussions with Nielsen which indicated a late decision as to using this device for a nuclear test or finding any device that could be done on a short term for a nuclear test in late Aug. and early Sept. Foster notes that the Livermore programs for a short, medium, and long range test program have been submitted to DMA and also that the Gnome experiment will be ready for detonation in Dec. 61. The final piece of correspondence in this folder is a 30 Sept. 61 letter from Foster to Betts which references several messages from DMA asking for Livermore's plans, proposals, etc. This letter contains details of a planned technical test program as well as device developments for the future. I will try to obtain a copy of this secret letter, No. BY 61~135, for our classified files. (/0 -\ “tesr PtLanis”all FILE)
