Safety Analysis Report (SAR)

Typically, a Safety Analysis Report (SAR) is a document which enables the regulatory body to assess the safety of a nuclear power plant. Preparing a preliminary SAR (PSAR) is part of the licensing process for new build nuclear power plants. Revision of a final SAR (FSAR) is usually part of the process of extending a license.

In the course of preparing or revising a SAR, government-specific requirements must be observed. In many countries, a PSAR provides the basis for the building permit while a FSAR serves as the basis for the operating licence. If safety-relevant modifications are implemented in the nuclear power plant after commissioning, a revision of the FSAR as well as a licence change application is usually required. In the Netherlands, the concepts of PSAR and FSAR are slightly different. Instead, a Safety Report (SR) and TIP (Technical Information Package) are required. The level of detail of the TIP is comparable to a SAR, whereas the SR contains a more general description of the nuclear installation. The SR is a public document.

NRG has extensive experience in the preparation and revision of Safety Analysis Reports, both for its own nuclear facilities and those of its customers (see references below). Our experts are familiar with the international standards for PSAR and FSAR (e.g. IAEA GS-G-4.1 and NRC REG-1.70.)

They can support your organisation in:

  • producing or assessing a PSAR / FSAR and revision of parts thereof
  • conducting studies to support the Safety Analysis Report
  • consulting the regulatory body.
