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.

It has been observed that high-velocity coolant flowing through the channels of a parallel-plate fuel assembly will at times cause large deflections of the assembly plates. In the present investigation, hydraulic equations are coupled to the plate equations along the entire length of the assembly. Solution of these coupled equations was accomplished by changing the differential equation developed from plate theory into a non-linear integral equation. The classical method of successive approximations was used to evaluate the integral equation numerically. Numerical results show that: 1) plate deflections take place along the entire length of the plate, and 2) local reductions in channel cross section are further reduced by elastic deflections of the plate.
