Subject:
External Inspections of DW in Sandbed Region In response to a question by Mike last night, I talked to Pete Tamburro this morning about the external UTs.
Currently, Pete's spec has not been revised and is still specifying 16 locations to be examined. There are 19 locations that were less than 0.736 inch thickness; however, 3 were in bays that were not originally planned to be accessed and inspected. One of our recommendations could be to inspect these other 3.
Mike mentioned a figure of 125 inspections done externally in the sandbed region. Pete could not confirm the number without going to the data sheets and counting up the number of inspections. The 19 subset were the locations under 0.736. The remainder were above 0.736. All locations inspected are located on the data sheets; therefore, re-inspections in the locations above 0.736 can be done with reasonable assurance that the readings would be close to the areas originally inspected. Pete noted that not all the areas were prepared by grinding. If the surface was reasonably flat such that a good reading could be taken, prep's were not done. Locating such areas would be done by the horizontal and vertical measurements on the data sheets.
Pete said he sent Ahmed a copy of the calculation (the '24' calc) that has the data attached.
Any questions, let me know. John phz~e~~C/f- 0~ ~Y 56'cy-og- a
