[en] The SECURity Officer Response Strategies (SECURORS) approach provides a method for determining security force deployment locations within a nuclear power plant to interrupt sequences of adversary actions which could lead to a radioactive release. The technique is applied to a nine-level generic nuclear power plant to determine locations for deployment subsequent to detection of an adversary intrusion. The security officers are deployed to intercept the adversaries at points along the adversary intrusion paths, since the security force generally is not large enough to deploy one security officer to each vital area (sabotage target). This general deployment approach is in contrast to a response to the specific area(s) where the alarm or intrusion occurred. Extensive use has been made of the facility layout drawings, the facility region information, and the pathfinder critical path results - available from the Safeguards Automated Facility Evaluation (SAFE) analysis of the nine-level facility - in order to focus on the problem of security officer deployment and to relate the SECURORS method to a currently available facility analysis methodology
