Swiss nuclear power and the case for long-term operation
Designed for 40 years but built to last far longer, Switzerland’s nuclear power plants have all entered long-term operation. Yet age alone says little about safety or performance. Through continuous upgrades, strict regulatory oversight, and extensive aging management, the country’s reactors are being prepared for decades of continued operation, in line with international practice.

Analysis is performed on the production and destruction rates of recycled transuranics (TRUs) in a light water reactor (LWR) fuel assembly using a Monte Carlo-based fuel depletion code (MONTEBURNS 2.0). Thirteen TRUs were recycled into the LWR model through ten 3-yr burnup cycles for a total depletion period of 30 yr. The focus of the research was to determine the relative reduction of TRU waste within the fuel cycle and determine the impact of the recycled TRUs on fuel criticality, waste toxicity, activity, and heat-load production. The amount of TRUs could be reduced by more than a factor of 4 for a 30-yr period when these 13 isotopes were recycled.
