The Margin Management Information System (MMIS) is a web browser accessible, non-QA-controlled data management system designed to capture important data and references that are identified in accordance with the nuclear design margin management program procedures. The MMIS is used to store and manipulate all data and references, provide assistance with data entry, and monitor the progress of the work.
In addition to the various limits and margins described in INPO AP-929, "Configuration Management Process Description", the Margin Management Information System accommodates margins for various parameters from a plant’s technical specifications, such as technical specification limits, settings, setpoints, and limiting conditions. It also includes INPO definitions for Margin Management terms to assist users in data entry. Sample data is included to aid the user during initial familiarization.
Because Margin Management information is an integral part of overall plant configuration management, the MMIS is designed to export MMIS data into future Configuration Management Systes (CMS). When this transfer is made, the appropriate level of Quality Assurance can be applied to the data for final verification and validation.
The MMIS is designed for multiple concurrent users, and is made available will full support for technical and MMIS related questions for 90 days at no additional cost.
