Sweden signed the Convention on 20 September 1994. The Convention was ratified about a year later, on 11 September 1995, and it entered into force on 24 October 1996. The first national report on the Swedish implementation of the obligations under the Convention was issued in August 1998. The following national reports were issued in August 2001, 2004, 2007, 2010 and 2013. All reports are available on the CNS website as well as on the website of the Swedish Radiation Safety Authority (www.ssm.se). The reports were discussed at the review meetings held in 1999, 2002, 2005, 2008, 2011 and 2014. A summary of highlights and issues raised about Sweden during the sixth review meeting held 24 March–4 April 2014 can be found in Chapter A. This section also includes an overview of the issues Sweden was asked to report on in its seventh national report. The Swedish Radiation Safety Authority was assigned the task to co-ordinate the work to compile and produce the seventh national report on behalf of the Government. A six persons working group with four representatives of the regulatory body, the Swedish Radiation Safety Authority, and one representative of each of the reactor owners, Vattenfall AB (further Vattenfall) and Sydkraft Nuclear Power AB (further Sydkraft NP), produced the report. The present report is structured in the same manner as the previous Swedish national reports. Chapter A includes basic facts and information about the Swedish nuclear programme to provide the reader with a frame of reference. Chapter B includes facts and information to substantiate compliance with the obligations of the Convention. Each Article under Chapter B corresponds to one Article of the Convention. Articles 6–8 are structured to allow for information, in accordance with the Articles, to be provided in a clear and reviewable manner. Articles 9–16 and 19 have a similar basic structure where information is provided about the regulatory requirements related to the corresponding Article and measures taken by the licence holders to comply with the regulatory requirements. These Articles also includes information about the licensees own safety initiatives as well as on regulatory oversight/supervision. Articles 17 and 18 are structured considering the templates provided by the special working group of experts. They contain the same information but the structure may differ from the other Articles. Altogether, this information will provide evidence for meeting the obligations of the Convention. Recommendations on the report structure issued as guidelines INFCIRC 572 Rev. 5 have been taken into account. In addition a template has been used which was developed by a group of experts to support the Contracting Parties by providing suggestions to be considered during the preparation of their reporting on Articles 17 and 18. The sixth review meeting of the contracting parties to the Convention on Nuclear Safety resulted in a number of topics to be considered while preparing national reports for the seventh review meeting. The agreed topics are reflected and the results presented in the report. 2 3 Ds 2016:30 As a result of the Diplomatic Conference to Consider a Proposal by Switzerland to Amend the CNS, the Vienna Declaration on Nuclear Safety was adopted by consensus by the Contracting Parties, on 9 February 2015. It contains three principles to guide the Contracting Parties, in the implementation of the objective of the CNS. These principles are reflected in this national report with special focus on Article 18 as well as other relevant Articles, including 6, 7, 14, 17 and 19. The general conclusions on Swedish compliance with the obligations of the Convention are reported in the executive summary. 4 3 List of abbreviations ALARA As Low As Reasonably Achievable (a principle applied in radiation protection) ANS American Nuclear Society ANSI American National Standard Institute BAT Best Available Technique BSS The Basic Safety Standards Directive of the Euratom BWR Boiling Water Reactor CAP Corrective Action Programme CCF Common Cause Failure Clab Central Interim Storage Facility for Spent Nuclear Fuel DBA Design Basis Accident BDBA Beyond Design Basis Accident EDG Emergency Diesel Generator ENISS European Nuclear Installations Safety Standards ENSREG European Nuclear Safety Regulators Group EPRI Electric Power Research Institute EU European Union EUR European Utility Requirements FKA Forsmarks Kraftgrupp AB (licence holder of Forsmark NPP) FSAR Final Safety Analysis Report IAEA International Atomic Energy Agency I&C Instrumentation and Control IEEE Institute of Electrical and Electronics Engineers INES International Nuclear Event Scale INPO Institute of Nuclear Power Operations IRRS IAEA Integrated Regulatory Review Service KPI Key Performance Indicator KSKG Kärnkraftssäkerhetskoordineringsgrupp (Nuclear Safety Coordination Group of the Swedish licensees) KSU Kärnkraftsäkerhet och Utbildning AB (the Swedish Nuclear Training and Safety Center) KTH Kungliga Tekniska Högskolan (Royal Institute of Technology) LER Licensee Event Report LILW Low and Intermediate Level Waste 4 5 List of abbreviations Ds 2016:30 LOCA Loss of Coolant Accident MSB Myndigheten för samhällsskydd och beredskap (Swedish Civil Contingencies Agency) MTO Interaction between Man, Technology and Organisation MVSS Multi Venturi Scrubber System NAcP EU stress test National Action Plan NDT Non Destructive Testing NKS Nordic Nuclear Safety Research Norderf Swedish-Finnish Group for Operating Experience Feedback NPP Nuclear Power Plant (including all nuclear power units at one site) NPSAG Nordic PSA Group NUREG Nuclear Regulatory Guide (issued by the USNRC) OE Operational Experience OKG OKG Aktiebolag (licence holder of Oskarshamn NPP) OLC Operational Limits and Conditions OSART Operational Safety Review Team (a review service of the IAEA) PSA Probabilistic Safety Analysis (or Assessment) PSAR Preliminary Safety Analysis Report PSR Periodic Safety Review PWR Pressurized Water Reactor R&D Research and Development RAB Ringhals AB (licence holder of Ringhals NPP) RPS Reactor Protection
