AFFORDABLE DUST COLLECTION FOR HAND DEMOLITION TOOLS: A Look at What is Available for the D&D Professional

Original equipment manufacturers (OEMs) have been slow to embrace dust collection for the majority of these tools despite heavy pressure from Occupational Safety and Health Administration (OSHA) and Environmental Protection Agency (EPA) regulators. It is only with the recent addition of another layer of enforcement, the Renovation, Repair and Painting (RRP) rule, that the major tool manufacturers have begun to offer effective dust collection for their tools. These dust collectors vary in efficiency and ease of use, and add to the cost of the tool. Contractors must weigh the cost of the add-on against potential fines and the moral obligation to protect the worker’s health.

DESTROYING ONE OF EUROPE’S MOST HAZARDOUS NUCLEAR LEGACIES

Fifty-seven tonnes of highly-contaminated liquid metal from fast reactor research tested the minds of engineers and scientists in the UK for two decades. Now, after an operation that took five years to complete, the team working for a consortium of Babcock International, CH2MHILL and URS has completed arguably the biggest hazard reduction in the UK decommissioning sector to date.

SUMMER GEAR – Special Section

Every year, thousands of workers become sick from occupational heat exposure. Some cases even become fatal. These illnesses and deaths are preventable when workers are trained to follow heat-stress safety protocol, and when they are given the proper equipment to help them stay cool and safe while working outdoors or in hot indoor environments. In the field of nuclear decommissioning and remediation, workers are often covered from head to toe in protective gear aimed at shielding them from harmful and hazardous materials. It is important to integrate heat safety and cooling measures into this equipment in order to ensure overall safety in every capacity.

Disassembling NASA’s Plum Brook Reactor…with Long Handled Tooling

The 60MWt Pressurized Water Reactor (PWR) at NASA’s Plum Brook Facility (PBRF) operated from 1962 to 1973 with full power operations totaling 98,000 MW-days. Between August 2003 and February 2005, a 9-foot (2.7m) x 31-foot (9.4m) tall PWR and the Reactor Vessel Internals (RVI) were disassembled and packaged for removal from the site in Sandusky, Ohio, US.

The Beauty of Decommissioning

Too often in environmental design, visual quality—aesthetics—is misunderstood as only a minor concern, dependent on volatile taste and thus undefinable. Yet a substantial body of research indicates the importance of visual quality in the environment to the public and has uncovered systematic patterns of human response to visual attributes of the built environment.

CLEAN-UP CHALLENGES IN OAK RIDGE

Tearing down the huge Manhattan Project facilities at the former K-25 site, now known as the East Tennessee Technology Park (ETTP) Heritage Center, and disposal of the hazardous and radioactive waste generated by their demolition pose some of the most complex environmental remediation challenges in the Department of Energy (DOE) complex.
