No, none of the engineers can do this.
I tried to change the file ___Kerbal Space Program\GameData\NearFutureElectrical\Parts\Utility\nuclear-recycler-25
{
name = RadioactiveStorageContainer
DangerousFuel = DepletedFuel
SafeFuel = EnrichedUranium
// What enginer level is needed to transfer the safe fuel
EngineerLevelForSafe = 1
// What enginer level is needed to transfer the dangerous fuel
EngineerLevelForDangerous = 3
// Max temp for transferring fuel into or out of the part
MaxTempForTransfer = 400
// kW of heat per unit of waste
HeatFluxPerWasteUnit = 5
}
Changing the number at the lines EngineerLevelForSafe = 1 and EngineerLevelForDangerous = 3 only changes the displayed text on the screen. In other reactor configuration files the same code.
