Posiva aiming to submit a construction licence application in 2012

The TKS–2009 programme prepared by Posiva, outlining the research, development and technical design work related to spent nuclear fuel disposal, was submitted to the Ministry of Employment and the Economy at the end of September.

The programme report describes the research, development and technical design to be carried out during the next three years, aiming to produce the licence material which is still required for the construction licence application that will be submitted in 2012.

 

At the same time with the TKS–2009 programme, the Ministry was provided with the final disposal facility’s pre-licence material for the construction licence application (construction licence readiness report). The material shows the current readiness of the reports required for the repository’s construction licence application, and specifies what parts of the material required for the construction licence still need to be supplemented.

 

The research, development and technical design aiming to obtain a licence for the repository includes the conclusion of the verifying studies of the Olkiluoto final disposal site, planning the required plants, and developing the deployed repository technology to the level required by the construction licence application. Moreover the research, development and technical design aim to produce a safety case to be annexed to the construction licence application. Along with the basic planning of the final disposal, the feasibility and long-term safety of an alternative, so-called horizontal disposal plan (KBS-3H) is being reviewed in co-operation with the Svensk Kärnbränslehantering AB.

 

The construction licence application to be submitted in 2012 will be prepared for an entity consisting of two final disposal facilities: an aboveground encapsulating plant and a repository which consists of underground final disposal facilities and other underground facilities (central tunnels, access tunnel, shafts, auxiliary facilities and technical facilities) as well as aboveground buildings (such as a ventilation building) that directly serve the repository.

 

The final disposal of 12,000 uranium tonnes of spent nuclear fuel is the starting point for preparing the application material. The amount of fuel comprises the final disposal of spent nuclear fuel from the existing nuclear plant units of TVO and Fortum, the Olkiluoto 3 unit (under construction), and the planned Olkiluoto 4 and Loviisa 3 units.

 

According to Posiva’s schedule assumptions, the construction of the Olkiluoto final disposal facility will commence in 2014 once the construction licence application has been submitted two years earlier. The intention is to submit the operation licence application in 2018 and to start the operation of the final disposal facility in 2020.
