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.

Adsorption isotherms for xenon on AGOT-grade graphite, having a surface area of 0.64 meter2/ gm, were determined at −79, 0, 20, 30, and 80°C in order to determine whether the presence of helium affects the adsorption behavior of xenon. The isotherms obtained from xenon-helium mixtures were essentially the same as those obtained using pure xenon gas. The calculated heats of adsorption for xenon range between 3500 and 3700 cal/mole and approximate the heat of vaporization of 3270 cal/mole reported in the literature. The volume of xenon adsorbed (cm3 at STP) per gram of graphite, a, versus xenon partial pressure, p (mm Hg), may be expressed by the equation a = bp0.8 over the ranges of temperature and pressure investigated. The values of b are 2.14 × 10−4 and 6.33 × 10−5 at 0 and 80°C, respectively. Based on straight line extrapolations of log plots of the adsorption isosteres to higher temperatures, b would have values of 6.5 × 10−6 and 4.1 × 10−6 at 500 and 750°C, respectively. Adsorption isotherms for argon were determined at −83 and 0°C and can be expressed by the same equation indicated above. At −83° and 0°C b has values of 1.00 × 10−4 and 1.60 × 10−5, respectively.
