approximately 90 days in advance of the estimated detonation date. This 90 days would be broken down into 60 days of additional construction time plus 30 days user occupancy time. By so utilizing their funds LRL would effect tees we emeereemmnncenenecenee . Not actually an NTS Planning Board document but an inhouse Livermore memcrandum from R. Petrie to W. Gibbins, dated 11 May 1959, concerns the construction at NTS versus the projected funding picture and in particular outlines the recommendations for the continuation or fiscal year 1960 construction within funding as quoted by Sewell in a 23 April memorandum. The basic philosophy is to obtain the best utilization of available funds to maintain an increasing 90-day capability which means construction on each side tunnel would be stopped T a sequential increase in the number of tunnels in a state of 90-day readiness. The tables and figures in this memo note the presently approved and ongoing work in tunnels Ul2e05 and O4,on safety tunnels U12i, j and k,and in tunnel U12b03 as well as the fact that funds have been allocated for other activity like postshot exploratory work, LASL safety holes, granite dicging and other things in FY 'S9. LRL lays out here the details of recommended work to be done in tunnels B and E and G, I, J and K and the amount of estimated cost and time it would take to reach 90-day readiness for these various shot locations. Oa "353.4 TEST MORATORIUM ({ MAY 1959 THROUGH 31 MAY 1963)" Folder This Is a continuation of the notes on these particular folders which were begun in the previous time frame filed under Ref. letter C. A 14 May 1959TWX from Starboard to Bradbury and Teller discusses the NTS vortex facility and Starboard states that the initial justification would ce. PCAN be based on its use forjexper iments, Que to am he asks for a joint the grave implications of going forth with this progr of the experiments, study by LASL and Livermore of the probable benefits could be used to assure the types of experiments, and those measures which that the expected this would not be exceeded, and he would probably use the future of The Yor tex joint study in talking with the commission about facility. 14 May 1959 notes the high level A TWX from the 4950th to the 4951st dated deere a study now going bn to investigate reducing support at the EPG to Caretaker Status and the impact on the 4951st. Ls Lf Wignall notes that command Gen. Canterbyry (Commander of AFSWC) desires that AFSWC retain control at Eniwetok.
