Step 2

The Preliminary Safety Report (PSR) was submitted to the regulators as part of Step 2. The PSR sets out a high level overview of the safety case, the environment case and the security claims for the proposed nuclear reactor design.

The main objective of the PSR is to provide sufficient information for the regulators to carry out Step 2 GDA and the scope of the report was agreed with the regulators during Step 1.

The PSR sets the initial structure of the Pre-Construction Safety Report (PCSR) which, through Steps 3 and 4 of the GDA process, will provide the arguments and evidence to substantiate the safety case claims.

For ease of access, the document has been split into 27 chapters as shown in the table below.
