Particulate control for coal-fueled diesel engine exhaust

Description: The Core Separator is a cylindrical vessel having one tangential inlet and two outlets at the opposite end of the vessel. It contains an outlet for the clean flow and a second outlet for the recirculating flow. The solids-laden flue gas is introduced through a fan to the inlet of the Core Separator. Due to the swirling motion of the flow, solids move to the periphery as the central jet leaving the system through the central outlet is cleaned of particulates. The peripheral flow with most of the… more

Electrochemical Methods for Reprocessing Defective Fuel Elements and for Decontaminating Equipment

Description: Reprocessing of fuel elements receives much consideration in nuclear engineering. Chemical and electrochemical methods are used for the purpose. For difficultly soluble materials based on zirconium alloys chemical methods are not suitable. Chemical reprocessing of defective or irradiated fuel elements requires special methods for their decladding because the dissolution of the clad material in nitric acid is either impossible (stainless steel, Zr alloys) or quite slow (aluminium). Fuel elements… more

Aluminum recovery from coal fly ash by high temperature chlorination

Description: A study of aluminum recovery from power plant fly ash by high temperature chlorination was undertaken to demonstrate that fly ash could be a potential source of aluminum, iron and possibly silicon. Magnetic separation of the iron oxide served as a first step to alleviate the iron contamination problem. However, the agglomeration of some iron oxide with alumina and silica made it difficult to completely separate the iron from the fly ash. Further iron separation was achieved by chlorinating the … more

Evaluation of dust-related health hazards associated with air coring at G-Tunnel, Nevada Test Site

Description: The Yucca Mountain Project was established to evaluate the potential for storing high-level radioactive wastes in geologic formations. Hydrologists recommended that drilling or coring in support of characterization tests be performed dry. Dry drilling, or air coring, presents a concern about health protection for the drilling personnel. The rock generally has a high silica content, and natural zeolites are abundant. Some zeolites are fibrous, leading to concerns that inhalation may result in as… more

Test Plan for the overburden removal demonstration

Description: The removal of soil overburdens from contaminated pits and trenches involves using equipment that will remove a small layer of soil from 3 to 6 in. at any time. As a layer of soil is removed, overburden characterization techniques perform surveys to a depth that exceeds each overburden removal layer to ensure that the removed soil will be free of contamination. It is generally expected that no contamination will be found in the soil overburden, which was brought in after the waste was put in pl… more
