NM200UW Nuclear Underwater Laser Scanner
Company: Newton Research Labs, Inc.
Address1: 441 SW 41st Street
Country: United States
The NM200UW nuclear underwater laser scanner is a landmark technology
developed by Newton Labs in partnership with a major U.S. nuclear utility. This
new tool 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-
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
