INDUSTRIAL COMPLEX FOR SOLID RADWASTE MANAGEMENT AT CHERNOBYLE NUCLEAR POWERPLANT

摘要

In the framework of the preparation for the decommissioning of the Chernobyl Nuclear Power Plant (ChNPP) anrnIndustrial Complex for Solid Radwaste Management (ICSRM) will be built under the EC TACIS Program in thernvicinity of ChNPP, comprising:rn1. a solid waste retrieval facility (LOT 1),rn2. a solid waste processing plant (LOT 2) andrn3. a repository for the disposal of short-lived waste (LOT 3).rnAfter an International Tender the ICSRM Contract was awarded to RWE NUKEM GmbH. The Contract is arnturnkey project. It covers design, licensing support, fabrication, assembling, testing, inspection, delivery,rnerection, installation and commissioning of all three LOTs.rnLOT 1 comprises the installation of a retrieval facility for operational Low and Intermediate Level Short-LivedrnWaste (SILW-SL) and High Level Waste (HLW) currently stored in the XTO storage silo. Due to the Chernobylrnaccident, this storage also contains an unknown percentage of Long-Lived (LL) waste.rnLOT 2 comprises a plant for the sorting and segregation of all categories of solid radwaste and the processing ofrnthe solid LILW-SL generated from the previous retrieval activities (LOT 1) and from the routine operational andrndecommissioning activities of the ChNPP. LILW-SL will be packaged and immobilized for removal to the nearrnsurface disposal facility (LOT 3) whilst higher category wastes (LILW-LL and HLW) will be packaged, overpackedrnand stored in a temporary storage facility while awaiting the construction of an interim storage facility.rnLOT 3 comprises a near surface repository in the form of an engineered facility for the final disposal of LILWSLrnconditioned in LOT 2 and for wastes from other sources at Chernobyl in accordance with the requirements ofrnthe Ukrainian Nuclear Regulatory Authorities.rnThe paper will present the proposed concepts and their integration into existing buildings and installations.rnFurther, the paper will consider the safety cases, as well as the integration of Western and UkrainianrnOrganizations into a cohesive project team and the requirement to guarantee the fulfillment of both Westernrnstandards and Ukrainian regulations and licensing requirements.rnThe paper will provide information on the status of the interim design and the effects of value engineering on thernoutput of basic design phase. The paper therefor summarizes the design results of the involved design engineersrnof the Design and Process Providers BNFL (LOT 1), RWE NUKEM GmbH (LOT 2 and General) and INITECrn(LOT 3)
