Development of a Web-based Evaluation System for I and C Systems of NPP

Since I and C systems in nuclear power plants are getting older with time, they have raised many problems with aging, obsolescence, high failure rates, and etc. But there are few pertinent methods to objectively evaluate the current status of I and C systems. In addition, even though there is a methodology, it is very difficult to apply to I and C systems of nuclear power plants due to complexity or reliability of the methodology. Thus, to improve these problems related to evaluation and application of I and C systems, we are developing a evaluation system which embarks an objective evaluation methodology and works on internet for convenience. Users such as plant staff can take advantage of this system to evaluate the current status of I and C systems and make a maintenance plan, a replacement plan or an upgrade plan from the evaluation results
