Supply System Rewcnse 1.
As indicated in the initial response, pipe spool flo. DHR-412030-2 contained a total of eight (8) lugs. Our inspection indicated six (6) lugs were undersized which included the two (2) lugs identified i
in the flotice of Violation.
l Subsequent to information provided in the initial response, we have taken the following specific actions to correct the nonconforming conditions identified in 1-flCR-137-190:
o Field Change flotice flo. 211-1-81-150 dated 1
January 14, 1981 was initiated to~ provide the installing contractor with the technical i
direction required to remove the support lugs from pipe spool DHR-412030-2.
o flonconformance Report flo. 1-flCR-137-190 was subsequently dispositioned " Rework" by the Architect Engineer on January 21, 1981. The description of required disposition is contained in FCfI-211-1-81-150.
As a function of the flCR disposition process, the Architect Engineer has determined that all eight (8) lugs on pipe spool flo. DHR-412030-2 are to be removed. Additional lugs will be reinstalled in conjunction with the installation of the pipe support for the affected pipe spool and will be completed as part of the normal sequence of construction.

All results were satisfactory and supported by appropriate test reports. Affected areas were examined by the liquid penetrant method in accordance with J. A. Jones procedure NDE 001, Rev. 4.
Wall thickness of the affected areas was examined by ultrasonic thickness measurement in accordance with J. A. Jones procedure NDE 006, Rev. O.
Test data has verified that minimum wall thickness has not been violated.
