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...

Nuclear power plant steam generator replacement decisions involve roughly $1 B in capital and replacement power costs. SDG has been engaged in helping utilities make this type of decision for the past 20 years. For PG&E, we decided to change our analytic approach to include a Monte Carlo simulation. This paper discusses the results and the strengths and limitations of this analytic approach. Be...

There has been a lot of interest in generating electricity using nuclear energy recently. This is due to the features such source energy. The main part system reactor core, especially most widely used Pressurized Water Reactor (PWR). hottest system; security risks and economic possibilities must be considered. Controlling this can increase efficiency power systems. study presents dynamic model ...

Reaktor Daya Eksperimental (RDE) is a high-temperature gas-cooled reactor (HTGR) for electricity generation, heat and hydrogen production by Batan. Empirical numerical calculations are needed to strengthen the existing design. The method computational fluid dynamic (CFD) analyzes temperature distribution pressure drop along pipe. Batan RDE steam generator design has seven-layer helical pipe mod...

This work presents a comparison study between the state-space and polynomial methods for the design of the robust governor for load frequency control of steam turbine power systems. The robust governor is synthesized using the two approaches and the comparison is extended to include time and frequency domains performance, controller order, and uncertainty representation, weighting filters, opti...

Steam generator (SG) tubing in nuclear plant offers a barrier between the radioactive material and steam. Effective NDT of the SG tubing is mandatory to ensure the safe operation of nuclear power plants. Multi-frequency eddy current (EC) NDT is being exercised in the nuclear industry. Detection and subsequent crack profiling from the acquired EC signals is a challenging task once dealt with sub...
