As part of the refurbishment of the PS Personnel Protection system, the radioprotection (RP) buffer zones & equipment have been incorporated into the design of the new access points providing an integrated access concept to the radiation controlled areas of the PS complex. The integration of the RP and access control equipment has been very challenging due to the lack of space in many of the zones. Although successfully carried out, our experience from the commissioning of the first installed access points shows that the integration should also include the software tools and procedures. This paper presents an inventory of all the tools and data bases currently used (*) in order to ensure the access to the CERN radiological areas according to CERN’s safety and radioprotection procedures. We summarize the problems and limitations of each tool as well as the whole process, and propose a number of improvements for the different kinds of users including changes required in each of the tools. The aim is to optimize the access process and the operation & maintenance of the related tools by rationalizing and better integrating them.

In 2010, the refurbishment of the Personnel Protection System of the CERN Proton Synchrotron complex primary beam areas started. This large scale project was motivated by the obsolescence of the existing system and the objective of rationalizing the personnel protection systems across the CERN accelerators to meet the latest recommendations of the regulatory bodies of the host states. A new generation of access points providing biometric identification, authorization and co-activity clearance, reinforced passage check, and radiation protection related functionalities will allow access to the radiologically classified areas. Using a distributed fail-safe PLC architecture and a diversely redundant logic chain, the cascaded safety system guarantees personnel safety in the 17 machine of the PS complex by acting on the important safety elements of each zone and on the adjacent upstream ones. It covers radiological and activated air hazards from circulating beams as well as laser, and electrical hazards. This paper summarizes the functionalities provided, the new concepts introduced, and, the functional safety methodology followed to deal with the renovation of this 50 year old facility.
