The influence of the nuclear fuel cladding pre-oxidation on post-LOCA quench resistance was experimentally studied and then modeled. Adopting a separate effect approach, quenched high temperature oxidized samples were axially loaded in mechanical device. pre-existing oxide layer shows complex that interpreted modeled using simple approach reproducing main observed phenomena. A new correlation e...

Activation and safety analyses were performed for the ARIES-ST design. The ARIES-ST power plant includes a water-cooled copper centerpost. The first wall and shield are made of low activation ferritic steel and cooled with helium. The blanket is also made of ferritic steel with SiC inserts and Li17Pb83 breeder. The divertor plate is made of low activation ferritic steel and uses a tungsten brus...

Since all doctors at some point in their career will be faced with their role as a teacher, it appears desirable that future doctors are educated in didactic skills. At present, however, there are no formal opportunities for developing didactic skills at the majority of Dutch medical faculties. The main question of this study is: How do medical interns perceive the quality and quantity of their...

*Correspondence: Xiaojing Liu, School of Nuclear Science and Engineering, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai 200240, China e-mail: [email protected] During the loss of coolant accident (LOCA) of supercritical water-cooled reactor (SCWR), the pressure in the reactor system will undergo a rapid decrease from the supercritical pressure to the subcritical condition. T...

Nuclear power plant experiences a number of transients during its operations. These transients may be due to equipment failure, malfunctioning of process support systems etc. In such a situation, the plant may result in an abnormal state which is undesired. In case of such an undesired plant condition, the operator has to carry out diagnostic and corrective actions. When an event occurs startin...

Zirconium-based claddings with an outer chromium coating resistant to corrosion are studied and developed as evolutionary Enhanced Accident Tolerant Fuel (E-ATF) concept for light water reactors. However, in hypothetical LOss-of-Coolant-Accident (LOCA) conditions, following clad ballooning burst, the does not allow protect inner surface of cladding from High Temperature (HT) steam oxidation ass...
