5. The Nuclear Plant Maintenance Challenge
Nuclear plant operators need precise measurements of as-built components located in-vessel and in the cooling pond in order to:
Determine current condition
Track cycle-to-cycle degradation in these areas
Achieve a correct fit for fabricated replacement parts

6. The Nuclear Plant Maintenance Challenge
Plant operators have relied heavily on indirect measurement techniques, which lack the detail required to effectively determine the precise dimensions of a component:
“Ruler-on-a-stick” - using binoculars or a video camera to visually gauge dimensions from a pole-mounted ruler next to a component
Video scaling - better accuracy, but is based on computing distances between pixels displayed on a 2-D monitor
Example: This video frame shows a crack in a BWR steam dryer door.
While it is possible to determine the length of the crack, the width and surface condition can not be precisely determined by the means traditionally used.

8. The NM200UW Solution
The NM200UW Nuclear Underwater Laser Scanner delivers precise dimensional measurements in the underwater radiation environments found in BWR and PWR vessels
The NM200UW is a landmark technology developed by Newton Labs in partnership with a major U.S. nuclear utility.
The system combines rugged, industrial-grade hardware and electronics with sophisticated software to enable the generation of fully measurable CAD models.

9. NM200UW Software – The Key to Results
In-air laser scanners have existed for several years
Precise underwater laser scanning is much more challenging, especially within PWRs and BWRs
Newton-developed software makes underwater laser scanning possible

10. NM200UW Software – The Key to Results
NM200UW software compensates for water turbulence, heat and radiation to produce a point cloud of great detail and density
The point cloud, when processed by industry-standard 3-D software, produces CAD files with dimensions that correspond precisely to the original target object

17. NM200UW Scanner Operation - 1
The NM200UW operates by laser triangulation.
The projected laser line sweeps the target surface and the high resolution camera captures and records any deformation of the line as a point cloud enabling ultimate 3-D computation.
The NM200UW is designed to scan and capture much larger target areas, by combining several point clouds together to form larger composites.

18. NM200UW Scanner Operation - 2
The NM200UW is able to scan a target as close as 6 in. (150mm) and out to a distance of 3 ft. (0.9M) for a scan coverage area of 2.1 ft. x 2.9 ft. (65 cm x 88 cm)
The system measures underwater targets up to an accuracy of +/ (0.01mm)
Operators may select from several levels of scan quality via the user interface
The shortest, most coarse scan takes approximately 15 seconds, while the highest resolution scan takes approximately three minutes

19. NM200UW Scanner Operation - 3
Laser light color is maximized for water penetration. The specific wavelength of the laser allows for highest possible efficiency underwater transmission
The scanner camera only accepts the specific color produced by its own laser and LED lights, greatly reducing any contamination from stray light in the scanning environment.
The NM200UW is relatively immune from any other underwater work lights during operation

20. NM200UW Scanner Operation - 4
In the visual observation mode, the LED ring array on the head illuminates the area and the camera transmits a monochrome image to the control console screen to assist the operator for optimum positioning and on-site analysis.
The control console powers and communicates with the scanner through the cable via low-voltage DC power and signals with pictures and scan data transmitted via Gigabit Ethernet.
The scanner head can be deployed by a variety of methods, including pole mounting, an articulated arm, an ROV or other robots.
All data is permanently stored for later analysis and study.
