Project summary

The Project Purpose is to develop and to implement an upgraded NM A&C system components for Siberian Chemical Integrated Plant which would include application of appropriate NDA and DA procedures/means to material measurements and to interaction between SCIP accounting system and regional supervising authorities.

The development results must be implemented to control Russian National State NM A&C system and to use for the NM A&C system advancement at similar Russian nuclear facilities.

The Project continuation goals are as follows:

· to enhance quality and effectiveness of the NM A&C data processing by means of centralized computer system implementation;
· to accomplish NM A&C system development for Siberian Chemical Integrated Plant’s RCP;
· to test model developed during physical NM inventory;

The Project and its continuation meets ISTC objectives being addressed to technology development for environmental protection, to nuclear material accountancy enhancement and providing scientists and engineers formerly involved in nuclear weapon related activities, the possibility to re-orient their skills to the civilian sector.

Expected results of the Project will cover resolution of determined crucial problems for nuclear material accountancy and control within frame of elaboration of the National nuclear material accountancy and surveillance system. The results will contain:

· regulatory criteria applicable for nuclear material accountancy at specific types of fuel cycle facilities;
· feasibility studies for measurement system development based on the implementation of handhold NM control devices and application of non-authorized NM access control/indication instrumentation;
· principles and requirements for nuclear material data transfer;
· mathematical models and computer codes for evaluation of MBA’s MUF during physical inventory;
· accounting and control procedures for material in-transit/shipment;
· requirements for standardized data banks on accounting, analytical measurements, current calibration data, data on implementation of material access control instrumentation;
· prototype measurement devices for operators.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
