Development of AN On-site, Rapid, Environmental Radiation-distribution Monitoring System for Decision Making during a Radiation Emergency

Abstract The article provides examples of radiation emergencies (ES), emergency response measures aimed at protecting the public and territories, including applicability of a comprehensive monitoring system of the public security conditions. A special attention is paid to scientific approaches and research results aimed at optimization of information processes during the operational use of data from monitoring systems on the conditions status under radiation emergencies. Besides, the expediency and sufficiency of using two data sources producing reports was determined and justified if one of the data sources is a monitoring system. Based on the research results, other provisions concerning the management of information processes under radiation ES conditions related to the requirements for operational public notification were justified. In particular, schemes for constructing such systems under special radiation ES conditions, algorithms for their operation, operating modes, and some parameters that these systems should provide with were justified. The information subsystem as a part of the CSPPCM is a kind of information system for the prompt public notification, and the research results are quite relevant for it.

Radiation Monitoring System

Environmental radiation monitoring is one of the important efforts in protecting society and the environment from radiation hazards, both natural and artificial. The presence of three nuclear research reactors and plans to build a nuclear power plant reactor prompted Indonesia to prepare a radiation monitoring system for safety and security (SPRKK). The goal of the study is to provide an appropriate method for developing radiation monitoring system to support the development of nuclear power plant in the near future. For this preliminary study, the author developed a code program using Gaussian distribution model approach for predicting radionuclide release and individual dose acceptancy by human being within 16 wind directions sectors and up to 50 km distance. The model includes estimation of source term from the nuclear installation, release of radionuclides source into air following Gaussian diffusion model, some of the release deposit to the land and entering human being through inhalation, direct external exposure, and resuspension, and predicted its accepted individual dose. This model has been widely used in various code program such as SimPact and PC-Cosyma. For this study, the model will be validated using SimPact code program. The model has been successfully developed with less than 5% deviation. Further study will be done by evaluating the model with real measuring data from research reactor installation and prepare for interfacing with real time radiation data acquisition and monitoring as part of radiation monitoring system during normal and accident condition.

State Functions

For pressurized water reactor nuclear power plants, in order to prevent the release of radioactive substances into environment, fission product barriers (FPBs) are constructed based on the concept of defense-in-depth, including fuel clad, reactor coolant system (RCS), and containment; the status of these FPBs is then acting as an important dimension to decision-making of emergency action levels (EALs). For CPR1000 nuclear power plants, state functions defined in state-oriented emergency operating procedure (SOP) are used to characterize postaccident physical conditions; their degradation substantially represents the challenges on fundamental safety functions and then on the integrity of FPBs in like manner, so degradation of these state functions is referred to as determining initial conditions of each FPB, by which the link between SOP and EALs is established. Then, an intelligent FPB monitoring system (FPBMS) aiming to automatically monitor states of FPBs is developed, verified, and validated. The pioneering work, by building bridges between state functions and initial conditions of FPBs and then computerizing them innovatively, proves that dynamical monitoring of states of FPBs during accident evolvement and real-time indication of loss or potential loss of FPBs can be achieved, which is most helpful in decision-making of EALs.

Decision Making Processes

The system for monitoring the efficiency of regional tourist and recreational services in Russia has not fully been formed yet; it is rather fragmented and represents only accounting and analytical parts. At the same time, monitoring the effectiveness of regional tourism and recreation sector is necessary to improve management and decision-making processes by the coordinating structures. It can also be used as a tool to monitor implementation of the programs and strategies for the development of regional tourist industries. The article presents a unique adaptive-functional model of the system for monitoring the effectiveness of regional tourist and recreational services and defines the structural elements and the information base. The proposed monitoring system is based on the use of methodology for evaluating the effectiveness of tourism activities which involves evaluating the effectiveness of three aspects: social, economic and networking in the regional area of tourist and recreational services.
