?<r ~ RECORD OF TELEPHONE CONVERSATION DATE: May 11,1982,1:00 pm PROJECT: Midland RECORDED BY: Joseph D. Kane CLIENT: TALKED WITH: CPC Bechtel NRC J. Schaub N. Swanberg F. Rinaldi J. Mooney J. Anderson D. Hood C. Russell J. Kane B. Dhar W. Paris ROUTE T0: J. Knight H. Singh G. Lear S. Poulos L. Heller R. Landsman, Region III D. Hood J. Kane F. Rinaldi MAIN SUBJECT OF CALL: To discuss Phase 2 Issues - Auxiliary Building Underpinning ITEMS DISCUSSED: Consumers arranged this conference call to discuss review items related to Auxiliary Building underpinning. These items had been identified in a brief call on May 7,1982 by J. Kane to J. Schaub where the NRC Staff had expressed their recommendations on the following items: 1. Location of deep seated benchmarks DSB-ASl and DSB-AS2. The current hold on construction and field installation of monuments prevents the actual locations from being established. Consumers will provide actual locations when these benchmarks are installed and recognize these monuments are to be installed at a distance not to exceed 5 feet from the wall of the Main Auxiliary Building which is founded at Elevation 562. 2. Strain gage installation. The NRC Stuif's comments for correction of drawing C-1495 were accepted and the drawing will be revised. (Lower strain gages at Elev. 584 to 614 on Sectional View-Wall at Col. Lines 7.4 and 7.8 are to be reorientated 90 degrees and column lines H and G will becorrected). Bechtel will check why strain gage at Elev. 646 to 659 range was not proposed for Wall at Col. lines 7.4 and 7.8 and will get back to Staff. The vertica, alignment of strain gage on Col. Lines 5.3 and 5.6 at Elevation range 646 to 659 is being controlled by the need to avoid equipment obstructions on the wall. Consumers will make an analytical correction for the vertical alignment when evaluating strain gage 't i readings. e i
{ 3. Pier test procedures. Consumers indicated the dead load available in the existing structure for the reaction load in the pier load test is approximately 90 percent of the maximum design load. Consumers wished to further consider the Staff's recommendation to perform a plate load test where the maximum test load would be equal to 130 percent of the maximum design load and a pier load test at 90 percent of the maximum design load. Consumers accepted the Staff's recommendation for performing two in situ density tests and a minimum of five cone penetrometer tests on the soil at the bottom of the pier selected for load testing. Consumers also agreed to use bituminous coated plywood sheeting for reducing the effects of skin friction during the pier load test. Consumers wished to further consider the Staff's recommendation for requiring a rate of. settlement that would not exceed 0.005 inch per hour when controlling the length of time that the 90 percent test load increment would be maintained. To better explain what the Applicant intended when it indicated that it would make modifications to ASTM Dll43 as deemed appropriate, Consumers will provide the Staff with.the pier load test procedures that identify the proposed modifications. 4. Construction dewatering. The Applicant indicated its plan for construction dewatering during underpinning is nearly complete and will be provided to the Staff within a week. Most of the dewatering wells are already installed but additional wells are planned. The additional wells are to be installed with Q/A procedures that are similar to the permanent dewatering wells which were previously apprcved by the NRC Staff. Monitoring for loss of soil particles due to pumping will be conducted according to the agreements reached for construction dewatering of the SWPS. (April 2,1982 letter with enciesures, R. Tedesco to J. Cook). Consultants to Consumers indicated the already installed construction dewatering wells extend to the natural clay layer at approximately El 585. The Staff indicated that the anticipated plan for construction dewatering to be provided by Consumers should address the problem of handling seepage on the sides and bottom of pier excavations which extend below the bottom of the already installed wells. ( 5. Movement of Feedwater Isolation Valve Pit (FIVP).'. Consumers indicated its intent to assure transfer of the FIVP loading to the Turbine Building and Buttress Access Shafts by jacking the installed support system. It is not the intent of this jacking to restore the FIVP to its or'.ginal position but t I l l l t
.o rather assure transfer of the load. The procedure for future jacking which Consumers indicated they would follow at the February 1-5, 1982 design audit and which was found acceptable by the NRC Staff requires jacking of the FIVP back to its original position if the relative settlement between the Reactor Containment and the FIVP reaches a total settlement of 3/8-inches since the date that the piping connections were made. i I t i I =
