WebLow temperature heat contains very little capacity to do work ( Exergy ), so the heat is qualified as waste heat and rejected to the environment. Economically most convenient is the rejection of such heat to water from a sea, lake or river. WebLow level waste (LLW) is generated from hospitals and industry, as well as the nuclear fuel cycle. It comprises paper, rags, tools, clothing, and filters, etc., which contain small amounts of mostly short-lived radioactivity. It does not require shielding during handling and transport and is suitable for shallow land burial.

Low Temperature Waste Heat - an overview
WebLow Level Waste (LLW) contains relatively low levels of radioactivity, not exceeding 4 gigabecquerel (GBq) per tonne of alpha activity, or 12 GBq per tonne of beta/gamma activity. Most LLW comes from the operation and decommissioning of nuclear facilities. The waste includes items such as scrap metal, paper and plastics. WebBetween 1967 and 1978 low-level and intermediate-level radioactive waste were emplaced in 13 chambers in the Asse II mine.
