D. L. Quamme Site Manager Job 7220 Midland Project PNEUMATIC TESTING OF THE MAIN STEAM ISOLATION VALVES BCCC-8962

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 perform 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 permit the testing as out-lined below:

1)

Utilize Construction Work Plan (CWP) No.16-2ABB-M-2924, which has 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-1.00 will be prepared to cover the necessary QC inspection. This FIR and PQCI/IR re-quires the following documents to be issued as controlled work prints 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 h) M204 These referenced inspection records will not be closed until the DRR 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, b d Ip G. A. Hierzer Site Manager GAH/RJM/ajd O
