' Interim Report for a Problem Concerning(55(e) 05)Feedwater Piping Spools Description of the Problem
- During.a: Stone & Webster audit of ITT Grinnell, it was observed that the material used in'the fabrication of some feedwater piping spools did not meet
.all1the. impact testing' requirements of ASME Section III. Certified Material
~
LTest Reports,'for the. material in question, did not document'the test coupon heat treatment. duration and temperature as. required by ASME Section III, NB-2211.
Further inquiry revealed that the heat treatment of the test. coupon was in fact not performed. Eight feedwater pipe spools are'affected.
The material test coupons with the same heat lot numbers as those of the eight feedwater pipe spools have since been heat-treated and impact tested.
Impact
-test results are still being evaluated. Since the matter-is still being investigated,.a final reportLwill be submitted by April 27, 1984.
