As part of the Top Innovative Practice (TIP) Awards, the innovation award was granted to the team for Volumetric Inspections of Inaccessible Piping via Robotic Crawler. The Diakont team tasked with inspecting auxiliary service water (ASW) piping applied an innovative approach to determine the health of certain sections of buried piping. The approach used a robotic crawler to conduct ultrasonic examination inside critical, but uniquely configured, sections of the pipe. These line segments are a pipe-in-pipe configuration. Because these ASW line portions are sleeved, conventional excavation and ultrasonic testing cannot be completed to assure wall thickness meets minimum ASME Code compliance. By using the robotic crawler, the inspection of the ASW piping sections eliminated any human occupancy of the piping while yielding a complete volumetric examination; its use also reduced a cost of up to $3 million, including excavation, to less than $200,000.

"Diakont's innovative buried pipeline inspection service provided real integrity data on 300' of coated auxiliary service water lines without having to put personnel in confined spaces" Jonny Minder, director of energy services at Diakont, "increasing plant safety and efficiency is Diakont's primary goal."

"Innovations like the ones celebrated today help ensure nuclear power plants continue to run safely and stay competitive in today's marketplace," Sue Perkins-Grew, senior director of nuclear security and incident response, said at the TIP awards ceremony.

The TIP awards celebrate industry leaders for new practices, enhanced processes, and improved technology. To be considered for an award, the process or practice must be implemented and address one or more of the following criteria: innovations, safety, cost-savings impact, productivity/efficiency, transferability, communications, or vision and leadership.

Diakont was one of 12 awardees recognized at the awards luncheon in Atlanta. The award-winning team includes Exelon Corporation, Tennessee Valley Authority, Exelon Nuclear, North American Young Generation in Nuclear, and more.

Diakont was also nominated for a TIP award for innovative robotic underwater decontamination service provide during Spring 2017 outage. Diakont developed a hybrid ROV-crawler tool with a built-in brush assembly that swam throughout the plant's refueling cavity and adhered to floors and walls to decontaminate the surfaces. The cutting-edge method was so effective that no additional manual cavity decontamination was required after drain down. Preliminary surveys indicated that all contamination levels were reduced to <50K dpm/100 cm2, helping the utility meet their INPO/Industry collective radiation exposure goals

BLE2 Series Brushless Motor & Driver

BLE2 Series Brushless Motor & Driver

The BLE2 Series replaces our popular BLE Series and continues our brushless motor advantages by featuring an all new compact, high-power and high-efficiency brushless DC motor combined with a Driver that can be digitally set and controlled via external DC voltage or by the front panel. The BLE2 Series can easily compete with larger 3-phase inverter driven motors in many more applications, with built-in simple holding torque function, saving space and increasing performance thanks to the advantages of a brushless motor design. The BLE2 Series has a maximum speed of 4000 r/min, achieving a speed ratio of 1:50 (80 to 4000 r/min). The new motor structure is small than previous models and enables high power and high efficiency while incorporating easy setting, installation and wiring. The new motor connector offers IP66 degree of protection and allows for easy and direct connection between motor and driver with two available orientation of cable outlet direction.
