High temperature reactor

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

This paper also discusses needs and challenges associated with advanced instrumentation for the multi-loop facility, which could be further applied to advanced high-temperature reactors. Based on its relevance to advanced reactor systems, the new facility has been named the Advanced Reactor Technology Integral System Test (ARTIST) facility.

MYRRHA is a multi-purpose research reactor able to operate in sub-critical and critical modes and currently in the design phase at SCK•CEN. The choice of LBE was driven by its chemical stability, low melting temperature, high boiling point, low chemical reactivity with water and air and a good neutronic performance.
