Implementation And Investigation Of A Cylinder Counting System For Safeguards Monitoring

Implementation and investigation of a cylinder counting system for safeguards monitoring

Introduction

Two important issues related to nuclear materials safeguards are: 1) the continuous monitoring of uranium enrichment facilities to verify that undeclared special nuclear material is not processed and 2) that declared special nuclear material is accounted for. For both cases, the material enrichment and flow need to be monitored. This is of importance to both the National Nuclear Security Administration (NNSA) and the International Atomic Energy Agency (IAEA) in enforcing the elements of the Nuclear Non-Proliferation Treaty (NPT) and other agreements. The signatories of the NPT have agreed not to develop, manufacture or otherwise acquire nuclear weapons or other nuclear explosive devices and have accepted safeguards on all nuclear material used in peaceful nuclear activities. Traditional safeguards include designating material balance areas (MBA) throughout a facility. Several MBAs are common within bulk handling facilities. For some nuclear facilities, because of the itemized nature of most nuclear material, simple material control and accountability (MCA) is a sufficient safeguard. For example, a nuclear power plant receives and ships nuclear fuel assemblies. This work attempts to fill that need by developing a PM system specifically for the nuclear safeguards and for the verification of material processed. This work presents the research completed to develop a central monitoring system incorporating traditional nuclear safeguards with modern process monitoring techniques.

System Design

The Scanning unit analyzes the checked EAN Barcode esteem and the Process Barcode esteem with the reference quality. The vicinity of the item is sensed by the sensor associated with the data of the PLC and it demonstrates its vicinity to the PC where the Lab VIEW is running. The point when an item is discovered, then the COM ports are opened to get the filtered Barcode qualities from the Scanners. Lab VIEW is modified to contrast and it tosses the outcome with the PLC and the PLC demonstrations likewise and rejects the terrible items.

In the air we have a double-acting cylinder controlled by a valve 5/2 electrically operated spring return.

In the control we have three branches: on the 1st we have a shutter and a relay in the 2nd is the button on the piece and a counter relay, and finally, in the 3rd place a relay and another relay timer connected to above(Butts & Shenoi, 2012, pp. 144-148).

Operation button spare part is counting down to 7 and once arrived to this figure, the order is given to change the position of the cylinder rod. The pieces are going up to 10 and reach at the time it receives an order to change position to the cylinder rod, which returns to the starting position. In this way we make sure to have at the end of the day to 70% at one site and the remaining 30% in the other approximately (Corley, 2012, pp. 224-245).
