DECOMMISSIONING OF NUCLEAR POWER STATION

Decommissioning of Italian Nuclear Power Plants. Experience and Future Plans

This paper is to illustrate the experience and future plans for decommissioning Italian NPPs, and the new organization, set to manage the whole decommissioning problem. Italian NPPs were shut down in the 1980s, and “deferred decommissioning (SAFSTOR)” was the selected decommissioning strategy, due to the lack of a repository for the disposal of radioactive waste. In 1999 the liberalization of t...

Decommissioning Costs of Wwer-440 Nuclear Power Plants

Fortum Power and Heat Ltd. has revised the decommissioning plan for the Loviisa Nuclear Power Plant (Loviisa1 and Loviisa 2) at the end of the year 1998 [4-1]. The plan is based on immediate dismantlement after shutdownof the power plant. Experienced plant personnel will still be available to lead the decommissioning work. Onlythe radioactive plant systems, components and structures...

Financial planning for the decommissioning of a nuclear power plant

After their service life is over, nuclear power plants must be decommissioned. Accordingly, Sweden has a system with segregated funds to cover the costs. Payments to the funds are dictated by the results of recurrent cost estimates. Recently, differences have been observed between different estimations for the Barsebäck BWR:s. Therefore, the Swedish Radiation Safety Authority, who oversees the ...

MULTICRITERION SYNTHESIS OF INTELLIGENT CONTROL SYSTEMS OF GENERATING UNIT OF NUCLEAR POWER STATION

The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...
