Info

Regional Basic Professional Training Course (BPTC) on Nuclear Safety plant organization in assessing plant damage, planning and prioritizing response actions, and implementing strategies that delineate actions both inside and outside of the control room in the event of a sever accident. Decision‐making - the element of establishing responsibilities for authorizing and implementing severe accident management strategies. This responsibility should be clearly defined and incorporated as part of appropriate instructions and procedures Training - the element of defining and providing severe accident training to those persons within the plant staff who have been designated for a decision‐making and support role in severe accident condition. Computational Aids - the elements where resources/tools which can aide the organization are developed and made available to technical assessment and decision‐making staff to assist with the assessment of key plant parameters, system status, and plant response relative to accident management decisions and action. Verification - the element where, during the process of guideline development, verification that the guideline is technically correct, i.e. the correlations used are applicable and the numerical results are reliable for the specific plant, is performed and documented. Validation - the element where, the process and implementability is validated. The guideline should be tested accurate under simulated severe accident conditions. Self-Evaluation - self‐evaluation is the on‐going process to ensure the severe accident response capability is feasible, maintained and useful. ❙ 904 ❙
❙ 905 ❙ 16. In‐Plant Accident Management In this course we will focus on the SAM guidelines, explaining the structure, technical background and how it works. 16.3.2. Severe Accident Policy in Korea This section introduces how the severe accident has come into Korean nuclear power plants. The MEST(Ministry of Education, Science and Technology) issued a 「policy statement on severe accident of nuclear power plant」 on august 30, 2001. The policy requires that the safety goal, probabilistic safety assessment, severe accident prevention and mitigation capability , severe accident management program should be established for Korean NPPs. To cope with the government policy the KHNP (Korea Hydro & Nuclear Power) has performed PSA and developed both the risk monitor and SAMP for all operating plants. The policy can be summarized as following : Safety Goal - risk of prompt fatalities to an average individual in the vicinity of a NPP that might result from reactor accidents should not exceed 0.1% of the sum of prompt fatality risks resulting from all other accidents Probabilistic Safety Assessment - owner of NPP should assess safety of the nuclear power plant via probabilistic approach in order to find measures which can reduce the risk as low as possible. Severe Accident Prevention & Mitigation Capability - reactor containment should preserve its structural integrity and function as a barrier against fission product release in order to mitigate the consequence of accident even in case of core damage
