STRUCTURAL INTEGRITY ASSESSMENT TEMPLATE
Work Instructions
Topic specialists should use this template to record their assessment of the Structural Integrity aspects of a safety case. Assessment should be against the
requirements of SCR2015.
Exemplar Approach - This template should be used in accordance with the scope of the Assessment Instructions when the topic is included for assessment.
An exemplar approach may be sufficient if some material has been previously accepted and has not materially changed. For example a CMAPP or SEMS
from an existing, accepted safety case.
The template is one of a series covering all assessment topics, which together form a complete record of the safety case assessment and create evidence of
how the decision to accept the case, or not, was reached. The templates identify the specific regulatory requirements of SCR2015 for the topic and indicate
what the competent authority expects to find within a safety case to demonstrate that those requirements are met. The template complements the published
guidance that supports the regulations and topic sector guidance. The templates are available to promote transparency and assist duty holders in drafting
submissions.
Green text indicates regulatory requirements that are new in SCR2015.
Black text represents regulatory requirements that are contained in both SCR2005 and SCR2015.
Non Acceptance Issue - A Non Acceptance Issue (NAI) is a deficiency in the demonstration made within a safety case, which, if not resolved, will prevent the
case from being accepted under the relevant statutory provisions. Non Acceptance Issues must be sent by a formal letters to the duty holder requiring them
to be dealt with in the appropriate manner, giving the duty holder a clear understanding of how to address the deficiency.
Clarification - A Clarification is an explanation provided by a duty holder on request during assessment to enable the assessing Inspectors to be confident of
their interpretation of the information in a safety case. Clarifications are a routine part of assessment work and should be raised with a duty holder promptly.
Clarifications do not require formal letters. Communicating by telephone and email is sufficient. A meeting between the duty holder and relevant topic
specialists may also be appropriate in some circumstances for clarifications. Clarification is not a first stage before raising non-acceptance issues. Any
aspect that could credibly lead to a Non-Acceptance Issue should be raised as such in the first instance.
Design or Relocation Notification - Where the template is used to aid the inspection of a Design or Relocation Notification, Inspectors should consider if the
information provided meets the requirements of Schedule 5 of the regulations. The inspection must identify any Potential Non Acceptance Issues to draw to
the duty holder’s attention. Reference to these requirements outlined in Sections 4 of this template may be useful when forming an opinion. A record of the
inspection should be made in Section [X].
