Fennovoima is Finland’s third nuclear power company founded in 2007. Fennovoima will build a new nuclear power plant, Hanhikivi 1, in Pyhäjoki municipality located in Northern Finland. Currently Fennovoima is evaluating bids from reactor suppliers. Originally two suppliers, AREVA and Toshiba Heavy Industries were invited to bid for the plant but later also a bid from Rosatom were invited. The plant supplier will be selected in 2013. Platom is a Finnish company with extensive experience in radioactive waste management. In the beginning of 2008, Platom was assigned by Fennovoima as radioactive waste management consultant and to develop radioactive waste management strategy and to support Fennovoima in negotiations with plant suppliers in waste management aspects. Since Fennovoima has started, there have been some changes to the regulatory requirements which had to be taken into account while developing the strategy. One important change is due to the Government Degree 27.11.2008/736 which establishes a new waste category of very low-level waste following international development and the “new” IAEA waste classification. Other important change was introduced by the change 342/2008 to the Nuclear Energy Act allowing some nuclear waste to be delivered to another country for treatment. These and many more requirements had to be considered when developing the strategy. Early work by Platom was mostly done to support development of application for Decision-in-Principle. This was the first important licensing step for Fennovoima. Work started with studies and plans which were used by Fennovoima to gather the know-how required to draw up the application. Descriptions of waste streams and waste management technologies were developed as well as preliminary waste inventories and studies for final disposal, including preliminary dimensioning of the repository facilities. Based on these plans nuclear regulator’s preliminary safety assessment was performed. The work was successfully completed as in 2010 the Government of Finland granted Fennovoima a permit to build a new nuclear power plant. The work continued in 2012 when bids were received for EPR and ABWR type reactors. Plans developed earlier were elaborated into a detailed strategy and the proposed waste management solutions were evaluated. This allowed feedback from the bids into the strategy and to the bid specification and they both were developed. Also waste inventories were elaborated which allowed development of reactor design specific disposal strategies. The main objective of work has been to establish basis for safe and efficient radioactive waste management which meets all the relevant national and international recommendations, requirements and regulations, takes advantage of best available and state-of-art technologies and offers fit-for-purpose solutions. All the work was performed to accommodate requirement based management system.

With the ageing of nuclear facilities or the reduced interest in their further operation, a new set of problems, related to the decommissioning of these facilities, has come into forefront. In many cases it turns out that the preparations for decommissioning have come too late, and that financial resources for covering decommissioning activities have not been provided. To avoid such problems, future liailities should be thoroughly estimated in drawing up the decommissioning and waste management programme for each nuclear facility in time, and financial provisions for implementing such programme should be provided. In this paper a presentation of current decommissioning experience in Slovenia is given. The main problems and difficulties in decommissioning of the Zirovski Vrh Uranium Mine are exposed and the lesson learned from this case is presented. The preparation of the decommissioning programme for the Nuclear Power Plant Krsko is also described, and the situation at the TRIGA research reactor is briefly discussed.

Set Up

ABSTRACTA regulatory authority in the field of nuclear waste management will not be responsible for the waste management itself. The regulator will however be responsible for reviewing the safety of the waste management activities proposed and performed by nuclear power plant owners or special organisations set up to manage and dispose of nuclear waste. In this paper the regulator's need for R&D to develop competence in the assessment of nuclear waste management safety is discussed.

The nuclear power plant is required to supply a substantial amount of electricity for a densely populated country like Bangladesh. The government of Bangladesh has attached to a commitment to implement the Rooppur Nuclear Power Plant, and so Bangladesh will be the 33rd nuclear power-producing country after the successful construction of this plant. Bangladesh has planned to construct two power units (Rooppur-1 & Rooppur-2) with a capacity of 1200 MW, each of and is expected to go into operation in 2023. Russian Rosatom State Atomic Energy Corporation is constructing this nuclear power plant, which is the generation-3+ VVER-1200 model. But the main concern is how a third world country like Bangladesh can handle the tons of radioactive waste of RNNP. Radioactive waste i.e., a variety of solids, liquids, and gases which are produced during the generation of nuclear energy in a nuclear reactor. Depending on activity content, solid and liquid waste are disposed of in near-surface or deep geological facilities, and gaseous waste is dissolved by following some filtering process. If not properly disposed of or recycled, irradiation from radioactive waste will cause major problems for the environment. Various stages should be required for the removal of a tremendous amount of radioactive waste in a cost-effective way. This paper mainly delineates the proximate of radioactive waste management of RNNP and gives an account of (1) Radioactivity and radiation level, (2) Classification, (3) Treatment of solid, liquid and gaseous radioactive waste, (4) Reprocessing and packaging, (5) Storage and (6) Disposal.

Decommissioning cost including radioactive waste management for 1100 MWe nuclear power plant (BWR) was analyzed comparing multiple scenarios. The total cost of decommissioning nuclear power plant was first estimated including the radioactive waste management cost for the standard Japanese decommissioning case with 30 years of the project duration including approximately 20 years in safe storage. It showed that the cost relating to waste management accounts for more than half of the total cost. Focusing on the radioactive waste management cost, the duration of safe storage was varied as a parameter. The timing of waste disposal was a key parameter determining the waste management cost due to the decay of radioactive nuclides resulting in the decrease in the total volume of the radioactive waste, and the change in the ratio of the waste volume in the three radioactive waste categories (intermediate-level, low-level, and extremely low-level). The total cost showed the minimum value at around 60 years of the project duration balancing the waste management cost and period dependent cost for safe storage.
