We have investigated magnetic properties for reactor pressure vessel model alloys with variable Cu contents, subjected to neutron irradiation up a fluence of 9×1019 n cm−2. Unlike monotonic increase microhardness fluence, the major-loop coercivity decreases at higher and decrease becomes larger alloy containing amount Cu. The measurements first-order reversal curves (FORCs) high-Cu show that po...

This paper deals with the stabilization of a non isothermal tubular reactor in which convection, diffusion and chemical reaction occur. The is modelled by set non-linear partial differential equations distributed jacket temperature used as control input. Two stabilizing laws are derived using thermodynamic availability function Lyapunov function. It shown how closed loop performances, terms set...

The efficient operation of existing plants in the process industry requires their analysis through simulation together with power and heat integration by retrofitting. Pinch Analysis (PA) is a classical procedure to achieve this goal. Yet, a further integration can be obtained reducing the entropy generated in the chemical processes. Ammonia, important as raw material in many process industries...

When the feedwater valve at outage loop of floating nuclear power plant leaks, thermal stratification occurs in steam generator. It causes lower water temperature loop. The extent hazard this phenomenon cannot be directly determined by existing measurement parameters, which poses a threat to operational safety reactor. Therefore, study adopts two routes: data-driven combined with analysis syste...
