Delay in US warhead modernisation

left

The plan to modernise the US W76 warhead has fallen behind schedule.  The first production unit of W76-1 was due to have been produced by September 2007.

There are issues at the six government plants involved in the Life Extension Programme (LEP). One of the problems is at Y12, Oak Ridge. Y12 is responsible for refurbishing the Secondary part of the warhead. Frank Munger's blog on  Knoxnews reports:

Ted Sherry, the NNSA's chief in Oak Ridge, last month indicated that Y-12 was still grappling with the technical issues on the W76, and said a decision would be made in early 2008 on whether to proceed or how to proceed.

"We have done a lot of up-front work and work on trying to certify that (manufacturing) process, but we have not produced the first production unit", Sherry said

Steven Wyatt, NNSA spokesman, said on 24 January that no decision has yet been made.

As part of the W76 LEP a new processing plant for a non-nuclear special material has been built at Y-12, but the name of the material has not been disclosed.
