Nuclear policy

The new Atomic Act on Peaceful Utilization of Nuclear Energy and Ionizing Radiation was published as Act No. 263/2016 Coll. which replaced previous Act No. 18/1997 Coll. The new Atomic Act is effective from January 2017 and it follows the newest standards of the International Atomic Energy Agency and latest Euratom directives. The new Act brings new legal measures focused on protection against harmful effects of nuclear energy and ionising radiation.

Following the State Energy Policy and National Action Plan for the Development of the Nuclear Energy Sector in the Czech Republic (NAP) adopted in 2015, the government of the Czech Republic appointed Mr Jan Stuller as a government commissioner for nuclear energy starting June 2016. His main responsibility is to ensure the implementation of the NAP for the development of nuclear energy. He will co-ordinate the preparation and related changes of legislation that are going to be affected by the construction of new NPPs and the operation of existing power plants as well. In addition to these duties, he will also lead negotiations with strategic partners and stakeholders involved in new nuclear build.

Six companies are interested in building new reactors in the Czech Republic with construction estimated to start in 2025 and commissioning planned for 2035. Rosatom, EDF, Westinghouse, Korea Hydro & Nuclear Power, China General Nuclear Power and Areva and Mitsubishi Atmea have shown interest and responded to the request for information required by the Ministry of Trade of the Czech Republic.

During the summer of 2016, the company ČEZ a.s. submitted the necessary documentation to the Ministry of the Environment of the Czech Republic (MoE) in order to begin the process of the environmental impact assessment (EIA) for a new plant located at the site of the current NPP Dukovany. In the frame of the declaratory proceedings, the MoE received many comments and observations from various state agencies, local municipalities, civil initiatives, as well as public feedback from the Czech Republic and from Austria and Germany. Conclusions resulting from declaratory proceedings will be carefully considered in the EIA process, and its completion and handover to the MoE is planned in 2017. Further assessment, negotiations and the final statement of the EIA will be provided later, depending on ongoing amendments to the law.

Nuclear power

In March 2016, ČEZ received permission from the State Office for Nuclear Safety (SONS), which approved the long-term operation of NPP Dukovany unit 1. This permission is not limited in time. However, it contains more than 80 individual conditions for further operation, all of which must be fulfilled. During the year 2016, ČEZ collected all documents related to the authorisation of NPP Dukovany unit 2 operation and the documentation was submitted to SONS in January 2017.

Operation of NPP Dukovany, as well as NPP Temelin, was significantly influenced by unplanned and extended outages in 2016 because of additional inspections and repairs of hundreds of welds. This situation will also continue in the year 2017, and the arrangements of units operation and schedules of individual cycles were significantly modified as a result. For this reason, NPP Temelin units 1 and 2 outages lasted for three months in 2016. The longest outage was at NPP Dukovany unit 3, where the duration was 180 days, and the result was lower electricity generation, less nuclear materials and fuel fabrication (as reflected in the tables of this publication).

During the period 2015-2016, ČEZ a.s. decided to gradually build up a strategic inventory of fabricated fuel at the NPP Temelin site in order to reduce risk of operation disruption in case of delayed delivery of fresh fuel (i.e. fuel fabrication requirements increased in these years). The first spare reload was delivered in November 2015, whereas the second followed in November 2016. The ongoing project of improved fuel assembly with a higher content of uranium (increase from 465 kgU to 502 kgU) and enhanced lateral stiffness is progressing according to the schedule. New modified fuel assembly will be loaded in 2018. In 2016, an agreement was also concluded with Westinghouse Electric Sweden AB for the supply of services related to the development and licensing of the fuel design and the manufacturing and delivery of six leadtest assemblies (LTA).

Regarding the current spent fuel storage capacity in the Czech Republic, it consists of six spent fuel pools adjacent to the reactors (excluding reserve capacity for emergency unloading of full reactor cores), two interim spent nuclear fuel storage facilities located at the site of NPP Dukovany and one at the site of NPP Temelin.

Uranium mining

Czech production of uranium in the form of chemical concentrates produced by the state enterprise DIAMO in 2016 was 146 tU. Some of this (51 tU) was produced by remediation from mine water treatment at former facilities. Production at the Rozna mine was affected by the forthcoming end of normal underground mining, which was terminated at the end of 2016 upon government decision.
