Chernobyl - Short and Long Term Measures

In 1996 a study of alternative solutions to convert the Chernobyl Unit 4 and its present Shelter into an environmentally safe condition (Chernobyl Unit 4 Short and Long Term Measures) was elaborated by an international group of experts.
 
This comprehensive study involved a detailed analysis of several alternatives, looking at both immediate short term operational requirements as well as long term needs. An optimized approach with regard to safety and economic terms (Long Term Measures) was to be achieved. The international expert group elaborated a study report and proposed a Recommended Course of Action. This Recommended Course of Action defined a frame concept including a stepwise approach designed to result in a safe condition for the damaged Unit 4 and its current confining structure. It comprises the three phases:
  • Stabilisation and other Short Term Measures
  • Preparation for Conversion into an Environmentally Safe Site, and
  • Conversion into an Environmentally Safe Site.

This study formed the basis of discussions between the G7 Nuclear Safety Working Group (G7-NSWG) and representatives of the Government of Ukraine. It was to proceed with the implementation of the phases 1 and 2 of the Recommended Course of Action. It was decided that an integrated Shelter Implementation Plan (SIP) should be developed under G7 sponsorship.
