MAGNOX PIONEERS INNOVATIONS IN WASTE MANAGEMENT

Magnox, EnergySolutions (Magnox’ s parent body organization), and the NDA have developed and implemented an optimized approach to the decommissioning of the Magnox sites known as the Magnox Optimised Decommissioning Programme (MODP). The programme sets out what the business will deliver over the comprehensive spending review period, including pioneering innovative ways of working, accelerating Bradwell and Trawsfynydd sites to a state of care and maintenance, and carrying out safe and efficient cleanup. Other sites have also received additional funding to accelerate some decommissioning projects. Acceleration of work on key sites is counter balanced by a reduction in scope or deferred demolition across other parts of the programme. The MODP offers a savings of about £1.3 billion from the original Magnox decommissioning strategy.

MODIFYING REMOTE TECHNOLOGY FOR MAGNOX STORAGE POND

There are many decommissioning challenges remaining across the site at Sellafield where the use of remote technology is likely to be beneficial or even fundamental to successful delivery due to access constraints largely relating to radiological dose.

CLOSING THE COMMUNICATIONS GAP: Making the Case for Maximum Public Participation in Radiological Monitoring

Few tasks offer greater challenges than that of communicating information to the public on issues related to the nuclear world.

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.

USE OF HEPA FILTERED VENTILATION AS AN ENGINEERED CONTROL FOR D&D WORK

High Efficiency Particulate Air (HEPA) filters remove radioactive particles from the air and are used by the nuclear industry as an engineered control. The HEPA filters can be flexible and heat sealed into waste bags, 2 – 40 CFM filters used in respirators or glove bags, or larger filters mounted in ventilation systems. When mounted in a ventilation system, they capture airborne particles before they are spread or reach a worker’s breathing zone. Unfortunately, the use of HEPA filtered ventilation is not well understood. Most workers have had little or no training on how to use ventilation to capture airborne particles.

INFRARED CAMERAS Provide Threefold Bonus For Nuclear Decommissioning

One of the most novel industries where infrared cameras have proved particularly valuable and cost effective is nuclear decommissioning. Engineers in Idaho are using them to provide process feedback and monitor safety as residual sodium is removed from the primary vessel and cooling loops of the sodium-cooled Experimental Breeder Reactor-II (EBR-II). Infrared cameras provide images of infrared radiation, or heat energy, which is otherwise invisible to the unaided eye. Infrared radiation is part of the electromagnetic spectrum, which includes visible light. But unlike visible light, infrared has wavelengths longer than the human eye can detect.

ENERGY SPENT IN DECOMMISSIONING

Quite recently, I was taken aback when somebody asked me about the energy (e.g. Mwh or Petajoules, PJ) spent to demolish a NPP, and the innuendo was that the decommissioning-related energy could be comparable with the construction of the same NPP, and even to the energy generated by that plant. I must admit I had no answer to offer on the spot. And yet, I realized soon that this is an argument used at times by the anti-nuclear groups. Was this really a loaded question? I decided to launch an enquiry among my colleagues and friends and I am glad to share the results with you.

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.
