TASK ENGINE FOR JOB AND USER NOTIFICATION (TEJUN): A TOOL FOR PROTOTYPING COMPUTERIZED

摘要

Research on computer-based procedure (CBP) systems has found operational advantages overpaper-based procedures (PBPs) including reduced memory workload, increased automation, andfewer operator errors. A Nuclear Regulatory Commision (NRC) study (1995) found that procedurerelated issues have been implicated in 69% of reported events for nuclear power plants (NPPs).Despite the associated risk with existing PBPs, utilities are hesitant to be first adopters and researchis needed to validate systems in the context of modernized but largely analog Generation II maincontrol rooms. Existing implementations of CBP systems have started from the ground up and whereable to have tailored operations to support CBP systems. For existing plants this is a timeconsuming,expensive, and potentially risky proposition, which represents a substantial shift currentoperational practices. For example, plants have existing protocols for authoring and maintainingprocedures that serve as administrative controls over processes. Therefore, procedures serveorganizational and administrative purposes unrelated to the actual operator control of the plant. Areplacement computerized system must be able to replace existing functionality and dovetail withthese organizational processes. This document describes the functional characteristics and technicalspecification for a Computerized Procedure Engine (CPE) designed to meet the needs of modernizedUnited States (US) NPPs. The CPE is designed with flexibility in mind to satisfy a variety offunctional and research objectives.
