Our industry experience allows us to compile, review, and submit radiation protection documentation to regulatory bodies like the NNR and DMRE. We also offer project management solutions tailored to your operational needs in the radiation industry.
Pigging & Related Operations
During internal cleaning (also known as pigging) and verification of the integrity of the pipeline, a waste product termed “black powder” is generated and received with the receipt of the cleaning pig at each receiving station (Cawthorne, 2010a). Black powder is a worldwide phenomenon experienced by most, if not all, gas pipeline operators. In the gas industry, the term “black powder” is a colour-descriptive term loosely used to describe a greyish material that is generated inside the gas pipelines.
Black powder can be found in several forms such as wet with a tar-like appearance or dry in the form of a very fine powder. It is generated inside pipelines due to internal corrosion and that the composition of black powder is dependent on the composition of the transported gas. Typically, black powder comprises mainly of iron oxide and residual organic compounds. However, black powder may present a major health and environmental hazard as some black powder is contaminated with mercury and naturally occurring radioactive materials (NORMs) such as radium-226 and lead-210.
These, and other radionuclides, plated out on the internal walls of the pipes, since their parent radionuclides uranium-238 and thorium-232 are found naturally in the gas or the porous rock of the earth’s crust. Lead-210 has been shown to exhibit activity concentrations in the range of 6 Bq/g to 26 Bq/g (IAEA, 2003). This black powder may therefore pose a radiological risk to workers. The National Nuclear Regulator (NNR) Act, No 47 of 1999 (DME, 1999), determines that operations or facilities that handle materials defined as radioactive material should obtain nuclear authorisation to do so. A radiological safety assessment of the worker exposure is one of the documents that needs to be submitted to the NNR for the nuclear authorisation. This report covers the radiological safety assessment and survey results in terms of the aims, scope and strategy as described in Section 3 of the NNR licensing guide (NNR, 1997) and taking account of the applicable criteria as described in the National Safety Standards and Regulatory Practices (DME, 2006).
