Implementation of an Expanded Material Control and Accounting Program (MPCA) throughPerformance of a Gap Analysis and an Expanded MPCA Plan at the Mining and Chemical Combine

摘要

Since 1996, the Mining and Chemical Combine (MCC- formerly known as K-26), and the United StatesDepartment of Energy (DOE) have been cooperating under the cooperative Nuclear Material Protection,Control and Accounting (MPC&A) Program between the Russian Federation and the U.S. Governments.Since MCC continues to operate a reactor for steam and electricity production for the site and city ofZheleznogorsk which results in production of the weapons grade plutonium, one of the goals of theMPC&A program is to support implementation of an expanded comprehensive nuclear material controland accounting (MC&A) program. To date MCC has completed upgrades identified in the initial gapanalysis and documented in the site MC&A Plan and is implementing additional upgrades identifiedduring an update to the gap analysis. . The scope of these upgrades includes implementation of MCCorganization structure relating to MC&A, establishing material balance area structure for special nuclearmaterials (SNM) storage and bulk processing areas, and material control functions including SNM portalmonitors at target locations. Material accounting function upgrades include enhancements in theconduct of physical inventories, limit of error inventory difference procedure enhancements,implementation of basic computerized accounting system for four SNM storage areas, implementationof measurement equipment for improved accountability reporting, and both new and revised site-levelMC&A procedures. This paper will discuss the implementation of MC&A upgrades at MCC based onthe requirements established in the comprehensive MC&A plan developed by the Mining and ChemicalCombine as part of the MPC&A Program.
