The CSNI Action Plan in the Area of Safety Margins was set up by the Committee on the Safety of Nuclear Installations (CSNI),

Software-based systems are used and retrofitted in operating nuclear power plants worldwide. The failure modes of both hardware and software in these systems are to some extent different from the ana...

The International Reporting System for Operating Experience (IRS) is an essential system for the exchange of information on safety related events at nuclear power plants worldwide. The fundamental ob...

The Working Group on Codes and Standards (WGCS) aims to facilitate and promote international co-operation, convergence and reconciliation of codes, standards and regulatory requirements for pressure-...

The working group will be responsible for the programme of work in the CNRA regarding regulatory activities in the primary area of advanced reactors and associated installations. The term “advanced r...

The Working Group on the Regulation of New Reactors (WGRNR) examines the regulatory issues of the siting, licensing and regulatory oversight for all new commercial nuclear power reactors. The WGRNR f...

Boiling water reactors (BWRs) use light water as a coolant and a moderator. This water is converted to steam in the core and then passes through a turbine.

Digital instrumentation and control equipment (DI&C) transmits information in ones and zeros, and provides a number of advantages in nuclear safety.

New reactors are light-water reactors that are in the design or construction phases. Advanced reactors refers to reactors under consideration that are cooled by fluids other than water.

Codes and standards are technical positions that govern specific activities such as welding, fabrication, testing and non-destructive examination, and are crucial to nuclear safety operations.
