- 1) The value in the nuclear specification shows an upper value which contains fabrication tolerance.
- 2) Burn up (%) ((All depletion weight of 235U) ÷ (Initial weight of 235U))x100
- 3) The dimension of the contained fuels is within the dimension specified in (I)-Fig. D.1 through (I)-Fig. D.8.
- 4) One operation cycle of JRR-3 with JRR-3 aluminide fuels (standard type and follower type) is 35 days (27 days for reactor operation and 8 days for shutdown). Refueling work is carried out once in an 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). Follower type fuel: 300 days or more (2 fuels),
335 days or more (2 fuels),..., 965 days or more (2 fuels).)
- 5) The values in total activity and decay heat are based on the cooling time (day) in 4).
