What is Remote Monitoring Technology? Remote Monitoring Technology = RMT Technology to assist personnel in performing work activities remotely. RMT has been implemented in varying degrees throughout the nuclear industry and encompasses the following technologies: Area Monitoring Telemetry Video Communications Robotics

Reduce Personnel Dose by Using RMT Radiation Protection Challenges… Reduction in available, experienced RP Techs Decreasing annual, individual exposure limits Decreasing cumulative exposure INPO goals Increased material inspection and mitigation activities Increased work activities in high radiation areas Using RMT will help… Efficiently allocate personnel resources (doing more with less) Provide an automated method to Alert Technicians to changing radiological conditions ALARA Planning Tool The success of using RMT relies on skilled RP technicians

RP Job Coverage Using RMT RP organizational change RMT Central RP Technician RP Field Technician supporting the use of RMT RMT System Administrators Full coverage vs. intermittent coverage Field Tech Central RP Tech Field Tech

Reduction in HP Dose

Use of Remote Monitoring Technology Where we are now… RMT is mainly used by the Radiation Protection organization to remotely perform job coverage. Where we want to go… Opportunities exist for extending the application of this technology to benefit all disciplines. For example, having the ability to view and communicate with the work location allows for: Direct intervention by supervision to support repairs and complex tasks. Remote assistance of personnel in adherence to plant procedures. Computer advisories of conditions directly to worker. Expanded trending of plant conditions and archiving of significant work information. Investigation of steam and liquid leak locations.

RMT Working Group Formed in 2003. Group Objectives: Promote the use of Remote Monitoring Technology for ALARA and Radiation Protection applications Standardize the use of RMT through development of industry guidelines Industry meetings Website and discuss board Peer Reviews and Assessments Provide a forum for the exchange of plant experiences Advance the capabilities of RMT through technology development and plant demonstrations Tasked by EPRI, INPO, and NEI to provide guidance and development for general technology usage.
