Relative Value

The artificial intelligence (AI) is applied to the safety analysis in the South Korean nuclear power plants (NPPs). The reinforcement learning (RL) is one of promising skills in the wise manipulations for the nuclear safety analysis where the reward is a critical factor to make the modelling. In the simulations, Y-axis means the relative value which shows the quantity of the accident possibility. The highest value is 4.0 in 46.25th year in which the values are increasing gradually. Otherwise, the values in the case with Agent gradually decrease. The highest value is near initial stage, which means the operation in NPPs is comparatively unstable. In the result, the values in the AI based controller graphs are higher than those of the other one. The RL algorithm is expressed by the Agent in this modelling, which is the most important factor in the AI-based operation in NPPs.

The article analyzes the problem of possible threats with the use of aircraft captured by terrorists or controlled unmanned aerial vehicles in relation to nuclear energy use facilities. In the context of preventing acts of nuclear terrorism, the urgent task is to protect nuclear facilities from deliberate attacks by civilian airliners operated by terrorists. On the basis of the materials of publications, the influence of external extreme loads acting on the design of nuclear power plants, their features during the fall of aircraft of different types is studied. As a conclusion, the author notes that improving the safety of nuclear power plants and other radiation-hazardous facilities, minimizing possible consequences from aircraft strikes are important areas in risk management and their protection from acts of nuclear terrorism by combining organizational measures to combat terrorism and nuclear security measures.

The Difference

The dynamical assessment has been performed in the aspect of the nuclear power plants (NPPs) security. The physical protection system (PPS) is constructed by the cyber security evaluation tool (CSET) for the nuclear security assessment. The systems thinking algorithm is used for the quantifications by the Vensim software package. There is a period of 60 years which is the life time of NPPs' operation. The maximum possibility happens as 3.59 in the 30th year. The minimum value is done as 1.26 in the 55th year. The difference is about 2.85 times. The results of the case with time delay have shown that the maximum possibility of terror or sabotage incident happens as 447.42 in the 58th year and the minimum value happens as 89.77 in the 51st year. The difference is about 4.98 times. Hence, if the sabotage happens, the worst case is that the intruder can attack the target of the nuclear material in about one and a half hours. The general NPPs are modeled in the study and controlled by the systematic procedures.

LABURPENA: Lan honetan, honako hauek aztertzen dira: zentral nuklearren ustiatzebaimenak, Espainiako araubideari erreparatuta, baimenak berritzeko administrazio-prozedurarekin lotutako alderdiak, bai eta hobetu daitezkeen alderdiak ere, azken gertaerak, jurisprudentzia eta izandako legedi-aldaketak kontuan hartuta. Azterketak Garoñako zentral nuklearraren gorabeherak hartzen ditu ardatz, bai eta 2031. urtera arte ustiatzeko baimen-eskaera ere (duela gutxi eskatu da baimen hori, 2012an itxuraz zentrala betirako itxi ondoren). Aurrekaririk gabeko eskaera horrek berpiztu egin du gai hauen inguruko eztabaida (Segurtasun Nuklearreko Kontseiluan ere): arrisku nuklearraren pertzepzioa, eskaera horren egokitasuna, eta eskaera izapidetzeko prozedura. RESUMEN: El presente trabajo aborda el análisis de los permisos de explotación de las centrales nucleares a la luz del ordenamiento jurídico español, los aspectos relacionados con su procedimiento administrativo de renovación y sus aspectos mejorables a la vista de los últimos acontecimientos, jurisprudencia y reformas normativas acaecidas. El estudio se centra en el devenir de la central nuclear de Garoña y su reciente solicitud de explotación hasta 2031, tras su aparente cese definitivo a finales de 2012. Una solicitud sin precedentes que ha vuelto a reavivar la percepción del riesgo nuclear, la conveniencia de tal solicitud y el procedimiento a seguir en su tramitación incluso dentro del propio Consejo de Seguridad Nuclear. ABSTRACT: This current work deals with the analysis of the operation permits of nuclear power plants in the light of the Spanish legal order, the aspects related to its administrative procedure for renovation and the facets to be improved considering the last events, case law and normative reforms that have happened. The study focus itself on the future of the nuclear power plant of Garoña and its recent petition of operation until 2031 after its apparent final stoppage at the end of 2012. An unprecedented petition which has revived the perception of nuclear risk, the advantange of that petition and the procedure to be followed even within the own Council for Nuclear Security.

AbstractRadiocarbon (14C) is a radionuclide generated mainly through neutron-induced reactions in all types of nuclear reactors. Since most of the 14C released into the environment is in the form of gaseous emissions (CO2 and hydrocarbons), terrestrial plants are the primary indicators of increased 14C levels near nuclear power plants (NPPs). In 2013–2014, we collected samples of silver grasses (including common reed) and pine needles within 3 km of four South Korean NPP centers and measured 14C activities using accelerator mass spectrometry (AMS) at Seoul National University. The highest 14C activities were observed, respectively, in Wolsong>Hanul>Kori>Hanbit [220, 143, 127, and 123% modern carbon (pMC)].
