2010:37 Utvärdering av regler och normer för betongkonstruktioner i ...

English Summary
This report is the final delivery to the Swedish Radiation Safety Authority
(SSM) for the work undertaken within the Commission, "Evaluation of rules
and standards for concrete structures in Swedish nuclear power plants".
In the SSM's regulations and recommendations, there are at present no specific
requirements and adequate guidance on how concrete structures should
be designed in case of new buildings or verification analyses of existing
buildings.
The result of the work presented in this report constitute the basis for SSM's
ongoing regulatory project “Investigation regarding requirements for construction,
design, analysis and review of reactor containments and other safety-related
building structures”.
The project includes the following:
1. Summary of the regulations and requirements that have been applied
at the initial design and new construction of concrete structures at the
Swedish nuclear power plants (chapter 3).
2. Comparison and evaluation of relevant regulations published by the
European and North American authorities (chapter 4 and 5).
3. Comparison and evaluation of relevant codes, standards, guidelines
etc. for load-bearing concrete structures in different countries (chapter
4 and 6).
4. Conclusions and recommendations to the regulatory framework for
the design of load-bearing concrete structures at the Swedish nuclear
power plants (chapter 7).
Based on a comparison and evaluation of regulations from the U.S., Canada,
France, the UK, Finland and Sweden, as well as guidelines established by
the international organizations IAEA and EUR, the following general recommendations
are provided as a regulatory framework for the design of
load-bearing concrete structures at the Swedish nuclear power plants:
‣ The Eurocodes will replace the BKR design rules of Boverket as the
conventional building regulations on the construction of nuclear power
plants.
‣ A general review and updating of the existing industry standard Design
rules for buildings at nuclear facilities DRB:2001 is implemented.
Reference is made to the Eurocodes with regard to conditions of conventional
design rules.
Detailed conclusions and recommendations are given in Chapter 7.
