Policy Department D: Budgetary Affairs ____________________________________________________________________________________________________________________ Administrational aspects: Was it necessary to majorly change the internal administrational structure to adapt it to the new task? Did you encounter frictions in that change process? Are major administrational changes ahead to improve the structures? Yes, the administrative structure was changed to be adapted to the new tasks, to be implemented in the nuclear facility. A totally new directorate – Decommissioning was established and the structure of the enterprise was changed respectively, as well as its Rules of procedure, internal rules of the specialized divisions, instructions, programs, methodologies etc. No difficulties met by now. No significant administrative changes are foreseen. In case it is necessary for the improvement of the work, administrative changes might be done. Technical aspects: Which safety status has the facility reached? What has to be done technically to reduce safety risks further? Which technical challenges were encountered so far in the project? How did those influence costs and time frame? Have lessons been learned by technical challenges so far? After the removal of the spent fuel the facility is kept in a safe status for a long period of time. Radiological monitoring and radiological survey of the contaminated structures and materials are implemented. Environmental monitoring is implemented according to the regulator’s requirements. To decrease the risk and to maintain the concept of defense in depth, it is necessary to carry out decontamination of first circuit, of the assembly storage pool and after that to drain them. The challenges are entirely in the area of early planning and its contradiction with the subsequent phases of the projects. The projects, as a whole, during their management from KNPP accumulated delays of several years. As of today, during last 2012 year, the majority of the projects were transferred for management from Kozloduy PMU to International Projects Division of SERAW. SERAW, as decommissioning and RAW management operator is highly motivated to finalize and timely complete the decommissioning projects. Thus no delays in the projects transferred are observed. It is a continuous process there the technical challenges overcome help to increase the competence level of decision making and executive teams, involved in the decommissioning activities. 154
Nuclear Decommissioning: Management of Costs and Risks ____________________________________________________________________________________________________________ Which technical challenges do you see currently and in the near future? How are you preparing for those? As new technical challenges are identified: Completion of the radiological inventory of Units 3 and 4 – Turbine hall and Reactor hall; Verification of the radiological inventory for Reactor hall of Units 1 and 2; Completion of the projects such as: Decontamination and Defragmentation Workshop, sites for temporary storage of RAM and RAS and upgrade of the facility for regulatory control clearance; Completion of the projects for removal of historical RAW, ion-exchange resins and boron concentrate from ECT. Waste management aspects: Waste management is a necessary prerequisite for a smooth decommissioning. Do you have enough means to store, treat and dispose the wastes from decommissioning internally or externally? Did missing waste management means delay or obstruct your technical or regulatory timeframe? As a result of the decommissioning non-radioactive materials (scrub) are expected to be generated, as well as radioactive materials (RAM), radioactive waste (RAW) and non-radioactive waste. Four open sites are planned to be built for the storage of radioactive and non-radioactive materials. RAM will be stored in 20’ISO containers, and non-radioactive materials – in skip containers. RAM treatment aiming regulatory clearance is planned to be done in the Decontamination and Defragmentation Workshop. Treatment of the decommissioning RAW will be implemented in the existing RAW Treatment Workshop, situated on the Kozloduy NPP site. New depot for storage of non-radioactive household and industrial waste is planned to be built. At the moment the construction of Decontamination and Defragmentation Workshop is at technical design elaboration level. After its commissioning the enterprise will be able to accomplish all the activities related to collection, treatment, conditioning and storage of RAW at the respective sites. In the near future - in 2015 the commissioning of National Disposal Facility for LILW is foreseen and the biggest part of the RAW generated from the decommissioning and dismantling activities on Units 1-4 , will be disposed in it. In this way all the RAW management process will be considered as closed. Non-radioactive and radioactive waste management is a prerequisite for the good planning of the decommissioning process. The delay in the construction of whatever facility, included in the waste management process will lead to delay in the decommissioning process. The lapse of some of the facilities needed will lead to impeding of the decommissioning process and non-adherence to the planned terms of implementation. 155
