Strawbridge OFFICE LOCATION : Ebasco Force Account SUBJECT : J. Gutierrez memo W3QA-20517 (Dated August 26, 1982) As discussed with you and Mr. Gutierrez, it is rather difficult to project a months schedule for my department. Our assigned commitment is to support the LP&L Start-Up and testing needs. Our daily schedule is constantly revised, bas'ed on the requirements to support our commitment. At this time, we do have two projects of a long duration, and I have attached copies of our projected schedule for each. These schedules may not be absolutely accurate, but will provide you with enough information that you will be in a position to " monitor" our activities. The balance of our schedule will consist of, a) Daily P.O.D. itens, b') CIWA's, DCN's, NCR's, DN's and Punch List items to support the Critical Systems on Mr. Milhiser's letter, c) ClVA's, DCN's, NCR's, DN's and Punch List items sent to us for closure, for systems already released or scheduled for future release. In an effort to satisfy your desire to audit some of our completed work items, I have attached several pages of completed (or closed) work items. These pages are copies of what we distribute to various departments, in an effort to have them removed from the MTS report. You should be aware that when we complete an item, and sign it off, it is sent back through the process. We do not maintain copies, except through our Manpower Request log. As we have always done, we will cooperate with you in any way we can. It is requested that, if any deficiencies or errors are noted, I have the opportunity to review them with you for a possib'le explanation or corrective action, should that be necessary. I am not quite sure what problems Mr. Gutierrez thought you may encounter, but I would like to assure you that my people will assist you in this endeavor. MRS/je cc: J. Gutierrez L. V. Maurin L.

OFFICE LOCATION : Ehasco Force Account SUBJECT : Projected Schedule for Primary Sampling System (CCB Item 163) (DCN-IC-1053) As requested, we have developed a proposed schedule for the installation of the re-work required on the Primary Sampling System, Based on the directions of CCB item #163 and the estimate prepared by Ebasco. The referenced estimate included " Scheme A" and " Scheme B". Our proposed schedule is based on the numbers shown for " Scheme B". I have been advised of the pissibility of additional CCB items being assigned to our department, but have not included any items except #163 in this schedule. 1his schedule was prepared by personnel from my group and personndl from Bob Cosgrove's group. It is requested that you review this schedule, apply any coments you feel necessary or pertinent. After we receive your consnents, we will incorporate them into the final draf t. MRS /je cc: R.

Our estimate is as follows: 2204 Direct Craft Manhours 336 Ebasco Inspection Manhours 336 LP&L Inspection Manhours Our plan is to work 3 two man crews per shif t 8 hours per day on a 2 shift . basis. We anticipate completion of this work by September 25, 1982. We vill start bf disassembling the larger motors first and the smaller motors' last. We are proceeding in this manner because if problems are encountered, replacement bearings and seals would require longer lead time for the larger motors. We require close coordination with your inspectors on the 1st and 2nd shift so as to -4=1=4

  • e any dela-r to this schedule. Also, since LP&L provides'the lubricants and the lubrication equipment, we will coordinate use of ssue with your maintenance department.
