Client: Washington River Protection Solutions
Timeframe: : July 2022 –
Quality Requirement: NQA 1
Overview:Washington River Protection Solutions (WRPS) is the Tank Operating Contractor (TOC) for the U.S. Department of Energy Hanford site. As the TOC commences retrieval of the next series of tanks, timely procurement of smaller lighting technology is required to illuminate the tanks to meet critical schedule milestones. The requirement is for a lighting system deployable via the 4” risers giving omnidirectional light, greater total luminosity than the previously deployed system, radiation tolerant, and capable of operating for extended periods in the temperature conditions prevailing in the tanks.
The modular lighting system is made up of individual units (modules) that plug together. Equipped with radiation-hardened LED light units to deliver total radiant power of 20,000 lm[NM1] and a radiation-hardened cable which is deployed by an electrically operated cable reel. The light units are mounted at angles to provide directional illumination.
The modular lighting system has a largest dimension of 72.5mm (2.85”) to enable it to be introduced into a tank via a 4” diameter riser. Modules once connected can be rotated to create multi-angular light arrays. Light can be projected downwards, laterally and at an angle both downwards and upwards depending on the lighting requirement. The geometries of the stainless-steel enclosure serve to protect the LED light modules from direct impact during introduction into the tank via the 4” riser.
