Figure 1: From early seal testing in 1996 to full-scale deployment of the
joint-use, IAEA-accepted, T-1 Electronic Seal Platform in 2003; the newer
Sandia-developed T-1A platform is now being manufactured for use.
The primary purpose of utilizing remote nuclear material monitoring systems is to reduce
the radiation dose to personnel that would result from physical Daily Administrative
Checks (DACs) and physical inventorying of material required by the associated Material
Control and Accountability (MC&A) plans.
I. System Purpose
The Savannah River Site Material Control and Accountability program is built around
Department of Energy Order, DOE M 474.1-1A, Manual for the Control and
Accountability of Nuclear Materials. In order to satisfy the material inventory and daily
administrative check requirements set forth by the order while maintaining personnel
radiation doses As Low As Reasonably Achievable (ALARA), K Area needed a remote
but robust method for material safeguards monitoring of nuclear materials. Additionally,
it was expected that some or all of the materials being stored would require additional
safeguard measures based on proposed agreements between the United States and the
International Atomic Energy Agency (IAEA) inspection regime.
II. Basic System Information
Based on prototype testing and ongoing support initiatives, Sandia National Labs
Material Monitoring System (MMS) and Los Alamos National Labs NTvision video
surveillance system were chosen for implementation in multiple SRS K Area material
storage locations. The Sandia MMS for the Savannah River Site K Area is centered
around the T-1 Electronic Sensor Platform (ESP). The ESP provides the tamper
indications via a set of electronic sensors including case switches, temperature sensors,
motion sensor, battery voltage sensor, and the fiber-optic cable seal system. The ESPs
