Flow leakage due to cavitation erosion occurred at the socket welding part downstream of multi-stage orifice installed in auxiliary feedwater (AFW) pump recirculation line domestic nuclear power plant (NPP). To assess adequacy changed operating flow rate proposed by a NPP operator as corrective measure concerning AFW line, pattern eight-stage and connecting pipe depending on magnitude was predi...

While mechanical vapor compression is typically applied for the concentration of brine, new approaches that are less costly and energy intensive needed to facilitate minimal zero liquid discharge. Several variations reverse osmosis high-salinity desalination increasing recovery rates beyond pressure limitation conventional RO have been proposed in literature. The promise these enhanced entails ...

Indonesian electricity supply is still dominated by coal-fired power plants (CPP) more than 50%. Water consumption for CPP in Indonesia reaches 222 million kL/year. Meanwhile, 10% of Indonesia's population predicted to experience a clean water crisis 2045. Most the consumed will be disposed as wastewater, such cooling tower blowdown and boiler blowdown. Boiler temperature relatively high. Thus,...

During plant operation, corrosion products from feedwater, drain and condensate system accumulate on the secondary side of steam generator in form scaled deposits around tubes sludge piles top tubesheet. These increase potential for corrosion, affect fluid flow reduce heat transfer efficiency generator. Using data obtained during periodical eddy current examination tubing, information deposit l...

Inspection of components utilizing advanced examination techniques is becoming standard practice in the power industry. One of the critical aspects during this type of inspection is to have on hand criteria for acceptance or rejection of flaws found during these inspections. The examinations typically include the use of advanced ultrasonic techniques such as Linear Phased Array (LPA), Focused A...

Nuclear Power Plants are a complex system and need to be controlled very meticu lously to avoid any catastrophe from occurring. The safety and availability of the power p lant relies on the human operators both through their ability and reliab ility to ensure smooth and trouble-free plant operations. Train ing the operators on normal p lant operation, maintenance, fault d iagnosis and unforesee...
