operation cycle, and 4 standard type fuels and 2 follower type fuels are refueled in an operation cycle. Therefore, cooling time of fuels contained in the package are at a minimum of 300 days, and .._,
added 35 days in turn for every 4 standard type fuels and 2 follower type fuels. (Standard type fuel: 300 days or more (4 fuels), 335 days or more (4 fuels), ... , 615 days or more (4 fuels).
