NM200UW Nuclear Underwater Laser Scanner
Developed Specifically for the Nuclear Power Industry
The NM200UW nuclear underwater laser scanner is a landmark technology manufactured by Newton Labs . This new tool, developed by Newton in partnership with a major U.S. nuclear utility, solves a problem that has vexed reactor operators for many years: how do you precisely measure underwater the internals of a PWR or BWR?
The NM200UW system combines rugged, industrial-grade hardware and electronics with sophisticated, Newton-developed software that compensates for the disruption of turbulence, heat and radioactivity characteristic of the in-vessel environment.
The scanner has a demonstrated accuracy of 0.005" (0.127mm) or better, and is designed to work in concert with industry standard, three-dimensional software, producing a point cloud output so dense and detailed that a fully measurable CAD model can be generated.
The capability of the NM200UW to provide precise, reliable and efficient dimensioning of as-built features, as well as to track cycle-to-cycle degradation, is important to nuclear utility operators, who until now have relied heavily on less-accurate traditional measurement techniques such as video scaling, or local area measurements performed with a ruler attached to a handling pole.
- The NM200UW mapping head encloses a high-resolution video camera and a high-intensity LED ring array
- The console unit contains the camera control unit, a rack-mounted PC, flat panel screen and keyboard
- Newton Labs underwater scanning software
- Components are housed in two, high impact airline-transportable luggage cases
- Directional and speed controls for the optional PT200UW Pan-Tilt Arm come pre-installed in NM200UW consoles.
- The power/data umbilical cable is gel-filled gel-filled with LLDPE polyurethane jacket and a rated yield point of 80 lb/ft (11 Kg/M) with a standard length of 150 ft. (46 m); lengths up to 300 ft. (91 m) may be special ordered.
The January-February 2012 edition of the Nuclear Plant Journal published a detailed article about the NM200UW capturing precise measurements in a difficult BWR location within a short period. Read the article HERE.
