AUTHENTICATION SYSTEM FOR USE AT THE FAST CRITICAL ASSEMBLY (FCA)

Sandia National Laboratories, the International Atomic Energy Agency, and the Japan Atomic Energy Research Institute have designed an authentication system which will allow the IAEA to conduct independent verification of records produced by the Portal Monitor (P/M) and Penetration Monitor (PN/M) systems in the Fast Critical Assembly (FCA) facility in Japan. Authentication Controllers installed at the P/M and at the PN/M will provide passive monitoring capabilities and randomly simulate activation of critical sensors. The Controllers will record data tagged with time and date, and store this information for retrieval by an IAEA inspector using a personal computer. The Authentication Controller clocks are synchronized with the C/S system clock to facilitate comparison of the data produced by the authentication equipment and by the P/M and PN/M.
