== Description:== We request a partial release of Phase II Mechanical controlled doct'nents and work prints as listed in the attached Bechtel letter BCCC-8962. This will allow a pneumatic drop leak test to be performed on the (MSIV's) to resolve a potentially reportable problem with pitting in the packing areas and assure they will not leak in the upcoming Milestone of Unit 2 Turbine Roll. p/[ Signature:( f cc: 'JGKeppler, NRC Region III. w/a.

Reference:

BEBC - 8157 Bechtel has received notification from Crosby Valve Company that the Midland main steam isolation valves (MSIV's) have a potentially re-portable problem with pitting in the packing areas. Construction has been requested by Project Engineering to perfom a pneumatic drop leak test to assure the MSIV's will not leak and possibly affect the upcoming Unit 2 Turbine Roll. Specifically, the MSIV valve bodies must be pressurized to 100 psig through the valve body drain and then monitored for leakage. Based on the above, we request that a special release of the current mechanical FCR/FCN stop work be granted to pemit the testing as out-lined below: 1) Utilize Construction Work Plan (CWP) No. 16-2ABB-M-2924, which has L been prepared for this work and requires the use of dwgs. 7220-M118A-5-7 and 7220-M118A-10-4 as field work prints.

2) A Field Inspection Record (FIR) and QCIR MP-1.60 will be prepared to cover the necessary QC inspection. This FIR and PQCI/IR re-l quires the following documents to be issued as controlled work j

Drints to MPQAD: a) M342 e) M118-A-10-4 b) M490 f) M632 Sht. 2 c) M480 g) M632 Sht. 3 d) M118-A-5-7 These referenced inspection records will not be closed until the DRR l has been reviewed.-

3) When the mechanical document register is released, it is our intent to have QC compare the register to the documents listed in 2) above and resolve any discrepancies.

We request your reply on or before February 3, 1984. Very truly yours, Y 0 hy G. A. Hierzer Site Manager GAH/RJM/ajd e e e}}
