CRITICALITY INCIDENT DETECTION GEOFF DRUCE

CRITICALITY INCIDENT DETECTION Aims & Objectives to provide the IRMF community with an overview of criticality incident detection & alarm systems to discuss the requirement to assign the system with a ‘safety status’ (Nuclear Site Licence Condition) to describe the importance of criticality incident detection & alarm system testing to demonstrate that the demands of the safety status can be achieved to gain IRMF community acceptance of the UK CIDS Service Providers produced Good Practice Guide into the NPL suite of documents

CRITICALITY INCIDENT DETECTION What is criticality? An unintentional or accidental occurrence of nuclear fission When and where can it occur? When all engineering controls and procedures fail In an Aqueous process In a Metal process What measures do we take should failure occur? Rapid detection of the fission [criticality] Personnel evacuation to a safe haven [primary function] Warn of re-entry to the incident area Option to make a process ‘safe’ Remote assessment of radiological conditions Emergency Planning

CRITICALITY INCIDENT DETECTION Rapid detection of the criticality incident From Delafield & Clifton (SRD R ) Minimum credible event 1 E14 fissions Tissue dose in free 1 metre from an unshielded event/assembly Hydrogen Moderated Event 2 E-16 Gy/fission for Gamma 1 E-16 Gy/fission for Neutron Unmoderated Metal Event 0.5 E-16 Gy/fission for Gamma 3 E-16 Gy/fission for Neutron

CRITICALITY INCIDENT DETECTION Detectors Geiger Counters Ion Chambers Scintillation Junction Diodes Trigger Methods Dose Rate Integrated Dose Rate of Change

CRITICALITY INCIDENT DETECTION Criticality Incident Detection & Alarm System Detection System Audible Alarm - Primary Alarm Instantly recognised tone Time to alarm criteria of 200 E-3 S Human Factors Visual warning in high ambient noise areas >80 dB Visual Warnings - Secondary System Remote outputs Facility Control Room Emergency Site Control Centre Process Interface Process Shutdown Systems

CRITICALITY INCIDENT DETECTION Safety Status Safety Assessment Principles for Nuclear Plant Specific requirements for criticality Availability & Reliability requirements Failure to Alarm on Demand Safety Integrity Levels Consideration of post incident information Assigning the Safety Status* Detection & Alarm System Detection & Alarm System with positive process action *The detection & alarm system will not prevent criticality

CRITICALITY INCIDENT DETECTION Reliability & Testing Dual Redundancy Single point of failure criteria Type Testing To demonstrate fitness for purpose Periodic Testing To demonstrate the degree of certainty to function correctly Good Practice Guide for the UK Why? Agree common approach Who was involved? Part of the NPL portfolio
