The Sellafield nuclear facility in the UK comprises a highly complex suite of plants and processes. This in turn demands a consistent and high performance from Emergency Response teams and management in order to demonstrate readiness to respond and combat any nuclear emergency. In order to continue to improve such readiness, a comprehensive programme of development has been undertaken by the Licensee. The programme spans the totality of the emergency response cycle which is resolved into three broad areas: Preparedness; Response; Building Specific File. Within these broad categories the focus of the materials changes from broad and general materials in the preparedness section to actual scenario specific materials in the Building Specific Files Sellafield Ltd. provided the scope of work for the totality of the criticality response materials, known collectively as Criticality Accident Response Data (CARD). The UK National Nuclear Laboratory (NNL) was challenged to technically underpin, develop and present the information in a format and layout that would satisfy the requirements of consistency, brevity, simplicity and relevance. One of the key areas targeted for improvement, and the focus of this paper, was the criticality accident response information that sits within the Building Specific File. At this level of the emergency response cycle by necessity the information must be detailed and specific and enable the emergency responder to understand the problem and assist in formulating a recovery plan. One of the key challenges faced by NNL and discussed in this paper was how to provide the emergency responder with the greatest amount of relevant information in the simplest form. NNL solved this problem by presenting the information in a 'four-block' format which includes a common set of information in textual and diagrammatic form. This paper presents on overview of the criticality accident specific four-blocker, highlights the problems encountered and focuses on the new and innovative materials developed. (authors)
