DEVELOPMENT OF USER FRIENDLY APLICATION of KIANA ADVANCE COMPUTATIONAL COMPUTER CODE(KACCC) AND COMPARSION WHIT RODOS COMPUTER CODE FOR A RADIOECOLOGICAL ASSESSMENT DURING ACCIDENTAL & NORMAL RELEASE OF RADIONUCLIDES TO ENVIRONMENT

A dynamic dose model has been developed to estimate radiation doses and stochastic risks due to atmospheric discharges of radionuclides in the case of a nuclear reactor accident and normal operation.The decision support system KIANA ADVANCE COMPUTATIONAL COMPUTER CODE contains a large set of simulation models, data bases, user interfaces and system functionalities. However these many options resulted in heavy-weight and complex user interfaces difficult to handle by non-experts. For this reason a user friendly and light-weight access to the KIANA ADVANCE COMPUTATIONAL COMPUTER CODE functionalities was requested by the end users. This was fulfilled by the design and implementation of a new user interface named KIANA ADVANCE COMPUTATIONAL COMPUTER CODE -Lite. The main purpose of this redesigned user interface is to gentlylead operators through asequential line of input masks, hiding rarely used parameters (defaults are set) from the operator but still providing the possibility to access them if necessary. Additionally, the interface is strongly safeguarded to prevent operators from entering wrong input values. This is achieved by systematically checking input values and even suggesting occasionally best estimate parameters. KIANA ADVANCE COMPUTATIONAL COMPUTER CODE -Lite will be comparison with the RODOS-Lite (Ehrhardt and Weis, 2000) that is complemented by various simple but nevertheless extremely useful features such as online access to Google maps2 or source term visualization.the KIANA ADVANCE COMPUTATIONAL COMPUTER CODE has been DEVELOPMENT for calculating of RADIOECOLOGICAL effect FOR ACCIDENTAL and NORMAL RELEASE OF RADIONUCLIDES TO THE ENVIRONMENT. In addition to individual doses from different pathways for different age groups, collective doses and stochastic risks can be calculated by the model. The model can be coupled to any long-range atmospheric dispersion model which can calculate radionuclide concentrations in air and on the ground at predetermined time intervals or measurement data. Since the Chernobyl accident, there had been an increase in real world data to assess the capabilities of software, which are developed to calculate radionuclide concentrations in the environment and doses to human. Therefore, data related to Chernobyl accident and WWER-1000 REACTOR CAN BE used to validate the developed software of KIANA ADVANCE COMPUTATIONAL COMPUTER CODE. The validated software was then used to calculate radiological consequences in the case of hypothetical severe accidents at WWER-1000 REACTOR type .The newly developed software was run for different release times, and it was turned out that meteorological pattern as well as vegetation cycles of the plants were influencing doses to humans.
