F. Schauer, Chief, Structural Engineering Branch, DSS
- 5. Pawlicki, Chief, Materials Engineering Branch, DSS FROM:
J. P. Knight, Assistant Director for Engineering, DSS
SUBJECT:
WPS-2 Jim Henderson called me today to ask that, if at all possible, a representative from the Structural and Materials Branch attend a meeting with the WPS-2 applicant on Wednesday, February 6, at 9:00 a.m. in the licensing hearing board room on the 5th. floor, B/W Towers.
The applican' has had so many The background for the meeting follows:
t problems constructing the sacrificial shield that I & E has talked them into stopping work. Jim Henderson fears that the proposed fixes will result in sufficient changes to characterize an unreviewed safety problem.
It seems that the shield is no longer cylindrical and in addition to being distorted is of questionable structural quality.
In addition there are large A-36 structural elements with what Jim describes as pretty high NDTT: the I
applicant is apparently proposing some scheme for maintaining higher than l
nomal temperature to compensate.
As always in these situations, there will be heavy pressure to review the proposed fixes so that the applicant can continue construction. This kind of problem deserves our best shot to define the scope of the effort i
necessary for a competent review. Please let me know if you can not cover the meeting with a staff member of sufficient seniority to speak for the branch and following the meeting please give me your assessment of the matter and an estimate of the review effort needed, if you detemine that step to be necessary.
