Increased Risk

Nuclear power plants (NPP), being complex technological systems, represent a source of increased risk, in particular, a specific risk of radiation exposure. Obtaining quantitative assessments of radiation risk is critical for risk reduction and accident prevention. Existing methods for assessing radiation risk do not take into account the influence of external factors, such as population composition, geographical features, anthropogenic environmental changes, etc.[1]. Since 1997, in connection with changes in the norms and rules in the field of the use of atomic energy, it became necessary to perform a probabilistic safety analysis (PSA) at all nuclear power plants in Russia. Subsequently, a standard safety data sheet for a hazardous facility was developed. To fill out the second section of the safety data sheet, it is necessary to carry out a risk assessment of the objects in question. From this moment on, risk assessments were performed for all power units of all operating nuclear power plants in Russia. Today, in our country there are 14 nuclear power plants. On average, there are 3 power units per nuclear power plant. In order to systematize and centralize data on NPP risk assessments, it became necessary to develop a program for monitoring NPP safety. The aim of the work is to develop a monitoring (control) program for ensuring the safety of nuclear power plants, using modern technologies to systematize and group data on nuclear safety data sheets, as well as organize quick access to information.
