Novovoronezh Safety Assessment Team Holds First Meeting. The first meeting of the project team responsible for overseeing the in-depth safety assessment of Novovoronezh Units 3 and 4 was held in Moscow on May 22 and 23. Members of the project team and the Russia management team were introduced at the meeting. The group discussed the status of task orders and the schedules for upcoming activities. Members of the group also proposed that the first steering committee meeting be held in mid-July 1997 at Novovoronezh NPP. A second meeting of the project team will be held in conjunction with the steering committee meeting. The team will schedule a training session on probabilistic risk assessment at Novovoronezh for either immediately before or after the July project meeting. Staff from Science Applications International Corporation will coordinate the training. (Jordi Roglans, ANL, 630-252-3283)

Further training needs for Ukrainian analysts and Ukrainian priorities for additional safety evaluation support also were discussed.

The U.S. team presented an overview of the scope of the U.S.-supported plant safety project relative to the Ukrainian in-depth safety assessment report requirements. The need for implementing peer reviews for the safety assessment was discussed. As a result, Derzhkomatom will explore which organizations in Ukraine can undertake this task.

On May 22, technical specialists from Argonne National Laboratory and Scientech met with Zaporizhzhya NPP representatives to discuss implementation of the safety assessment project for Unit 5. They reviewed details of the tasks for data collection and analysis and the Level 1 internal events probabilistic risk assessment, and agreed on computer hardware needs for the effort.

U.S. participants in completing the plan include experts from Stone & Webster Engineering Company, Parsons Power Group, Science Applications International Corporation, Bechtel Hanford Inc., and Scientech. The key European participant was Trischler and Partner. The work was done in close cooperation with the Chornobyl Shelter operations and Ukraine institutes. The Shelter Implementation Plan will support the development of G-7 pledges to the project. Those financial pledges are an expected outcome of the G-7 Summit scheduled for June 20 and 21 in Denver, Colorado.

The next step in the International Shelter Project is to 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.
