Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Secondary gamma-ray skyshine has been measured at an intense 14 MeV neutron source facility with a Hp-Ge detector used to investigate this mechanism. Many discrete gamma-rays due to (n, γ) reactions were observed in the spectrum. It was confirmed that in the evaluation of the secondary gamma-ray skyshine, a precise spectrum calculation down to thermal neutron is indispensable. On the other hand, there exists only a continuum spectrum up to 8 MeV with no discrete peaks in the real skyshine spectrum from the upper air. It was found that the continuum spectrum is composed of mainly Compton scattered gamma-rays. In the distance dependency measurement, the real skyshine contribution showed slow attenuation compared with the whole skyshine contribution. This means that with increasing distance from the facility the real skyshine contribution is gradually dominant, namely, it becomes more important in the skyshine evaluation.
