Non-Contact Underwater Measurement and Robotic Operating Tools for the Nuclear Industry

Newton Labs has developed revolutionary, non-contact machine vision, laser scanning and robotic tools enabling nuclear plant operators to rapidly complete precise, in-vessel core validations of fuel assembly positions, as well as to accurately gauge the as-built dimensions and conditions of pipes, pumps, valves and structures in underwater radiation environments.

The NM200E Core Verification System uses proprietary machine vision algorithms to accurately measure the positions of all fuel assemblies in a PWR nuclear reactor and compare them with ideal positions (supplied by the reactor operators). The result is detailed, accurate measurements of all fuel assembly locations, allowing reactor personnel to determine if there will be any issues with the installation of the upper internals.

*This technology enabled Exelon Nuclear to wins the Nuclear Energy Institute's 2012 Top Industry Practice (TIP) Award in the Maintenance Category for
“PWR Fuel Alignment Mapping System.”

The Core Verification System is the primary application and interface used to perform a complete core mapping in approximately one hour or even less.

The NM200UW Nuclear Underwater Laser Scanner delivers precise, non-contact dimensional measurements in the underwater radiation environments found in BWR and PWR vessels and in the pools, or other underwater plant locations. The system combines rugged, industrial-grade hardware and electronics with sophisticated software to enable the generation of fully measurable CAD models from dense and accurate point clouds.

The Inspector Underwater In-Tank Robot is a highly maneuverable, semi-autonomous robotic platform that enables plant owners to meet the requirements of the Nuclear Energy Institute for tank inspection in accordance with NEI 09-14. An Inspector system has the ability to deploy a variety of advanced nondestructive evaluation (NDE) sensors over 90% of a tank floor and to map the position of any indications with an accuracy of 1/8th inch (3 mm). Surveys can be performed with the tank full or dry. An Inspector system is composed of the robot, an in-tank, hatch-mounted global positioning camera assembly and the operator's console.

The Surveyor Robot is a highly flexible fully antonomous or semi-autonomous robotic platform that allows utilites to inspect or perform operations in nuclear faclities. The robot has built in high resoluion prictures and laser scanners. The Surveyor robot can also carry various arms and can integrate tne data from many other different sensors including ultrasound, eddy current, ACFM and other sensors. The Surveyor can be equipped with wheels, Mecanum wheels, tracks and propeller pods or various combinations of motive options to provide required mobility. Surveyor operates in air or underwater.

The Reactor Pressure Vessel Inspection Robot is a reactor barrel measurement tool. The Newton RPV Inspection Tool measures with various sensors the condition of the reactor barrel and produces significant data including CAD models of the reactor barrel and of the lower internals. It also measures ovality of the ractor barrel as well as surface condition. The Newton RPV tool can be equipped with Laser Scanners, Phased Array Ultrasound, Eddy Current and ACFM sensors.
