develop bid packages for urgent early-start projects. Those bid packages
will be tendered as soon as possible to keep the shelter project on
schedule. U.S. participants in this effort will include Parsons Power
Group and Science Applications International Corporation. The key
European participant will be Trischler and Partner. The G-7 has selected
the European Bank for Reconstruction and Development (EBRD) to manage the
finances for the project and hire an organization to manage the work in
the field. Over the next several months, the International Shelter
Project team will work with EBRD and the Chornobyl Shelter operations
organization to develop the early-start project packages for tendering by
fall 1997. (Dennis Kreid, PNNL, 509-375-2170)
