[post_content] => For organisations operating in highly regulated industries, such as chemicals, nuclear or oil and gas, the management of by-products and wastes is a key concern. In order to comply with domestic and international guidelines, wastes must be managed safely and responsibly to prevent damage to the environment and the health of employees and the general population.
The nuclear industry in particular is highly regulated, with all radioactive waste produced during the generation of nuclear power required to be managed as hazardous material. According to the World Nuclear Association, this means waste must be isolated or diluted such that the rate or concentration of any radionuclides returned to the biosphere is harmless.
“For nuclear sector operators there are no second chances when it comes to ensuring waste and by-products are safely managed,” Bjoern Stolz, managing director of Thielmann WEW says. “Accidents can have serious consequences that can have knock-on effects for years, if not decades. For this reason, all equipment used to store and transport these products must be manufactured to stringent standards.”
The different types of radioactive waste need to be dealt with, loaded, stored and transported in different ways. Low-level radioactive waste (LLW), i.e. waste with a radioactive content that does not exceed 4 giga-becquerels per tonne (GBq/t) of alpha activity or 12 GBq/t beta-gamma activity, does not require shielding during handling and transport.
To support its customers active in this sector, Thielmann has developed a range of specialist containers for the short and long-term storage of Class 7 liquid products (including LLW). As the cost of managing and disposing of waste is a key driver for customers operating in this sector, Thielmann aims to enhance logistics simplicity and reduce lifetime costs.
“We do this by substituting road tankers with proven intermodal technologies, so that the tank system is separated from the trailer and fitted within a standard ISO frame that is compatible with load handling systems,” Stolz says. “The hook-arm system permits rapid prime-mover redeployment and guarantees interchangeability with other civilian vehicles throughout the supply chain.”
The tank’s double-shelled module solution integrates systems to prevent settlement of α and β particulate matter, ensure accurate records of product handles are kept, and provide data logging for customer visibility.
The unit is self-filling via a vacuum pump, as this reduces the reliance on moving parts as in the case of a traditional pump, and contact with the waste product is kept to an absolute minimum. Fitted with an industrial standard self-priming pump, flow rates of up to 45 m³/h can be achieved, delivering 5.5 kW at 400 V. The system can also be integrated with an air-activated carbon filter and the valve opening/pump operation sequence is controlled by a PLC controller.
Tanks can be integrated with accessories such as electronic overfill protection, digital filling level indicator and self-retracting power cord reels, and the system can be managed via a fully integrated control box with ‘fool proof’ operation.
As with all Thielmann tank containers, every aspect of each system can be engineered to match customer requirements, to ensure that all materials, no matter how hazardous, can be safely managed throughout the supply chain.
