Memo to : Executive Committee

P.6

3rd November, 1987

In compliance with specific instructions from NNSA and the Executive Committee, the JVC organised its PRC

JVC organised its PRC and expatriate experts to examine the technical solution proposed by the EdF designer and the related design information and analyses from the designer. It was established that the technical solution of EdF designere met the design criteria and was equivalent in structural strength, margina and quality to the original design.

A summary of the alternative technical solutions is given in Appendix 3. It is confirmed that the EdF proposal did not represent the cheapest possible solution. There were alternatives which would have satisfied the design criteria at lower cost but which were considered technically less desirable than that proposed by Edr.

The technical solution was issued to NNSA for review, NNSA confirmed verbally on 8.10.1987, and then in writing on 16.10.1987 that they had no objection to this technical solution.
