We will produce vitrified glass by continuously feeding

Tests using this facility are effective for analyzing theformation state of the cold cap on the melted surface,

Drone Technology: Advancing Safety andEfficiency in Thermal Power Plant Inspections
When inspecting thermal power generation facilities,
working at heights involves the installation and removalof scaffolding around the perimeter, the use of elevatedvehicles, and rope access, which can be hazardous. In
addition, divers who perform underwater inspections ofstructures often have limited time to work and are at
risk in culverted areas. For this reason, the use of drones
is effective.
By using drones equipped with real-time kinematic
capabilities, we can create 3D models with higher
accuracy than conventional drones with less effort.

CRIEPI Coat®
This coating prevents thinning and cracking of the sprayedcoating and sulfide penetration on walls. For boilers in thermal
power plants, this coating can prevent sulfide corrosion andhigh-temperature oxidation within the temperature range of
300°C to 700°C.
This coating is effective to prevent concurrent corrosion
where the groove corrosion occurs, and the progress of thegroove corrosion can be suppressed at the same time. In
addition, this coating can suppress the thinning and oxidation
on walls, and help prolong the lifetime of sprayed coating.

HEAF (Arc internal Test on theelectrical equipment(Electrical Cabinet, Bus Duct etc.))
High-Energy Arcing Fault (HEAF) events in electrical equipment(such as electric cabinets, bus ducts, etc.) are recognized as one of
the risks that impact the safety of power plants, such as thermal andnuclear power plants. Finding solutions for HEAF is a critical issue
worldwide. Only CRIEPI has conducted research and development
on HEAF fires and succeeded in standardizing the testing methods
and established the HEAF fire prevention method.
