The principles presented in the SAPs are supported by a suite of guides to further assist ONR’s inspectors in their technical assessment work in support of making regulatory judgements and decisions.  This technical assessment guide is one of these guides.\nPURPOSE AND SCOPE OF FUEL ASSESSMENT\nThis guidance covers design and operation of nuclear fuel and core components in reactor and its transfer from the fuel storage pond.  It deals with both the limits and conditions to be used during fuel operation in core and the design limits to be applied to confirm the resilience of the fuel in faults. Here fuel is taken to mean all components of the fuel assembly.\nThis Technical Assessment Guide (TAG) contains guidance to advise and inform ONR staff in the exercise of their regulatory judgment and to provide more detailed explanation of ONR interpretation of International Atomic Energy Agency (IAEA) safety requirements and Western European Nuclear Regulators Association (WENRA) reference level requirements.\nThis TAG is principally aimed at the operation of civil reactor uranium oxide fuel and restricts itself to information that can be openly published.  However, where the ONR inspector considers it reasonable to do so the TAG can be applied to the use of other fuels.\nRequirements for compliance with nuclear safeguards and measures to address threats from hostile third parties are outside the scope of this TAG.  Some nuclear safety related topics of interest to fuel & core inspectors are captured within other, interfacing TAGs (Ref. 2) – these are listed in Section \u0013 REF _Ref38016000 \\r \\h  \\* MERGEFORMAT \u00144.6\u0015.\nRELATIONSHIP TO LICENCE AND OTHER RELEVANT LEGISLATION\nIn the context of the Nuclear Installations Act 1965, a holder of a nuclear site license (the licensee) has a number of duties which relate specifically to fuel performance:\nLC 14 requires the licensee to make and implement adequate arrangements for the production of safety cases to justify the design, construction, manufacture, commissioning, operation and decommissioning of a facility.\nLC 20 and 22 require adequate control of modifications which may affect safety.\nLC 23 requires an adequate safety case to demonstrate safe operation and to identify the limits and conditions of operation to form the basis of operating rules.\nIn respect of other legislation, The Health and Safety at Work Act 1974 places duties on employers to provide and maintain plant and systems of work that are, so far as is reasonably practicable, safe and without risks to health.\nTh","cbCaiosOAEPMA7J4","https://ap.wps.com/l/cbCaiosOAEPMA7J4","docx",211054,26,"English","# Introduction\n# Purpose and Scope of Fuel Assessment\n# Relationship to Licence and Other Relevant Legislation\n# Relationship to SAPs, WENRA Reference Levels and IAEA Safety Standards Addressed\n# Advice to Inspectors\n# References\n# Glossary and Abbreviations\n# Tables\n# Appendices","[{\"question\":\"What does the Fuel Assessment TAG cover?\",\"answer\":\"It covers design and operation of nuclear fuel and core components, including transfer from the fuel storage pond.
