Comparison Table of SAR for Type JRC-80Y-20T Before after note Chapter : Safety analyses This package is designed to comply with the IAEA Regulations for the Safe Transport of Radioactive Material 2012 Edition concerning Type B(U) package containing fissile material. This chapter shows the summary of each analysis for the package.
(1) Structural analysis In the structural analysis of the package, the evaluation of the thermal stress and internal pressure under normal and accident conditions of transport is performed by means of finite element method code ABAQUS etc. Also, the evaluation for drop tests is performed by numerical analysis using finite element method code LS-DYNA.
As the results, it is confirmed that the package sufficiently satisfies all the requirements specified in the regulation. Namely, the following is assured.
Even if the package is subject to the pressure difference between inside and outside of the packaging and thermal loads under normal and accident conditions of transport, the package has sufficiently the containment and shielding performance required in the regulation, and there is no change of the configuration which affects the criticality and thermal analysis.
It is confirmed that there is no deformation which affects criticality analysis and thermal analysis except the basket for box type fuels which suffers a slight plastic deformation partially in 9m horizontal drop. For the basket for box type fuels which suffers a slight plastic deformation, it is confirmed that there is no influence which causes criticality in the critically analysis.

Therefore, a clearance between the body and the basket at the ambient temperature of -40 is 0.244 mm. And even when considering the expected ambient temperature change during transportation (from -40 to 38), since there will be no change in the temperature range for the same material, there is no difference in the expansion amount of the transport container body nor that of the fuel basket, and no change in the amount of gap either.

Comparison Table of SAR for Type JRC-80Y-20T Before After note omission A.4.6 Pressure omission The change on the stress corresponding to the increase in the internal pressure is obtained from the result of stress calculation due to only the internal pressure in paragraph A.5.1.3. The maximum stress (stress intensity) occurs in the inner surface at the center of the body bottom plate, and the value is 0.077 MPa (= 0.06x2.270.06).
Therefore, if the ambient pressure is reduced to 6.0x104 Pa, the effect of the pressure reduction upon the packaging can be ignored.
As shown in paragraph ()-C.3.1 2, the leaktightness test of the packaging is performed at the internal pressure of greater than 0.42 MPaG and has been verified that the containment of the packaging is secured. Therefore, the safety of the packaging can be secured without affecting its containment.
A.4.7 Vibration omission Therefore, 1 999 Hz Since the natural frequency of the package is about 999 Hz against the maximum effective frequency (approx. 50 Hz)15) which is predicted during transport, there will be no resonance during transport.
Therefore, various bolts used for the packaging will not cause resonance, and they will not become loose because they are provided with antirotation keys.

The maximum stress (stress intensity) occurs in the inner surface at the center of the body bottom plate, and the value is 0.077 MPa (= 0.06x2.270.06).
Therefore, if the ambient pressure is reduced to 6.0x104 Pa, the effect of the pressure reduction upon the packaging can be ignored.
In addition, in the evaluation of the strain level of the lid sealing boundary for the special test conditions shown in (II)-Table A.21, it was confirmed that the sealing property was maintained since the recovery of the initial clamping stress was confirmed and the mouth opening was less than 2.01 mm for an initial clamping allowance of 3 mm.
A.4.7 Vibration omission Therefore, f1 = 999 Hz Since the natural frequency of the package is about 999 Hz against the maximum effective frequency (approx. 50 Hz)15) which is predicted during transportation, there will be no resonance during transportation.
The relationship24) between the amplification factor and the ratio of frequencies is given by the curve shown in (II)-Fig. A.34. Here, since the expected frequency of vibrations during transportation is about 50 Hz, the amplification factor will be obtained as follows:
Ratio of frequencies f / fn 0.05 Where, fnNatural frequency of the package f: Frequency of vibrations during transportation Therefore, Amplification factor 1 Therefore, since there is no influence of load amplification due to vibrations during transportation, in addition, in the stacking evaluation ((II)-A.5.4) under the normal test conditions, considering the fact that the transport container will not be deformed even when it is subjected to five times its own weight + its own weight load, there is no risk of cracks, damages, etc. to the transport container due to vibrations during transportation.

Furthermore, an evaluation will be made on the loss rate of 10B in a hypothetical case of receiving neutron irradiation from the contents for 100 years to show that the boral plates do not lose their efficacy.
10B absorbs thermal neutrons and produces 10B (n, )7Li reaction.
The neutron absorption loss rate of 10B is expressed by the following equation:
(Neutron absorption loss rate) = (Neutron irradiation dose) x (Absorption reaction cross-section of 10B)
For the neutron irradiation dose for 100 years, using the value for fuel element B, which has the maximum source intensity per unit length, as shown in (II)-Table D.4, it will be:
1.03x105x100x365x24x3600 3.25x1014 n/cm2 Here, considering Absorption cross-section of 10B: 3837 x 10-24 (cm2) Note 1
- Then, 3.25x1014 x 3837x10-24x100 1.3x10-4 This means that the loss of 10B is negligible and the neutron absorbing ability of the boral plate will not be lost.
Cadmium wire is used as the neutron poison for JRR-3 standard silicide type fuel, and JRR-3 follower silicide type fuel, but this material is ignored in the analysis to evaluate conservatively.

Comparison Table of SAR for Type JRC-80Y-20T before after note F Consideration of Aging of Nuclear Fuel Package This chapter describes the matters which are to be considered in the safety analysis in Chapter (II) with regard to aging of nuclear fuel package component materials during the planned period of use of the transport container.
F.1 Aging Factors to be Considered For the nuclear fuel package, based on the anticipated conditions of use as shown in (II)-Table F.1, possible aging factors to be considered for the component materials of the transport container are thermal degradation, degradation due to irradiation, degradation due to chemical changes, and fatigue due to repeated stresses during container storage, before shipment, and during transportation.
The period of use of this package is 70 years from the time of manufacture, the frequency of use is once per year, and the number of days required for transport per transportation is conservatively 365 days. Assuming the number of handling times per transportation is 100 times, the total number of planned lifting times throughout the planned period of use is 7,000 times (100 times x 70 years) (A.4.4).
II)-Table F.1 Conditions of use anticipated during the planned period of use Status contents Conditions of use In storage No Transport containers are stored indoors.
In order to confirm that the performance of the transport container is maintained, a periodic voluntary inspection based on "Chapter (III) Maintenance of transport containers and handling methods of nuclear fuel packages" described in the application for design approval of nuclear fuel packages (Appendix-1) is to be performed at least once a year.
Before transportation Yes Nuclear fuel packages are to be stored indoors within the controlled area of the facility for up to three months from the time the contents are loaded to the time they are transported.
Before shipment of the package, a pre-shipment inspection based on "Chapter (III) Maintenance of transport containers and handling methods of nuclear fuel packages" is to be conducted.
During transportation Yes The package is to be transported by transport vehicle or vessel.
The package is to be securely tied to the vehicle or vessel so that it can withstand the shock and vibration Newly added chapter

expected during transportation.
The period of transportation is expected to be about 2 months.
After transportation No After transportation, a visual inspection is to be conducted in controlled area (indoor) of the facility to confirm the integrity of the transport container.
Transport containers are stored indoors.
F.2 Evaluation of Necessity of Considering Aging in Safety Analysis Based on the aging factors shown in F.1, the necessity of considering the aging of each component material of the nuclear fuel package was evaluated with regard to thermal, radiation, and chemical changes that are expected during the planned period of use.
Fatigue evaluation was also conducted for the lifting device, which is subjected to loads during handling, and for the sealing device, which is subjected to loads due to changes in internal pressure. The results of these evaluations are shown in (II)-Table F.2.

Component material Aging factors Evaluation Stainless Steel Heat Although there may be mechanical property degradations such as creep, etc. (deformation) by high temperature embrittlement due to exposure to a high temperature environment, the results of thermal analysis indicate that the temperature near the fuel basket center axis is 200 (the highest temperature during transportation is 223 for the fuel elements) (B.4.2), which is below the temperature (425 or higher) (1) at which deformation due to creep, etc. may occur. Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Radiation Although there may be effects on the mechanical properties due to microstructural changes (embrittlement, etc.) caused by neutron irradiation, the maximum neutron irradiation dose during the period of use is 2.27 x 1014 n/cm2, which is less than the dose of 1016 n/cm2(1) that may cause microstructural changes (embrittlement, etc.). Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Chemical changes Although there may be effects of corrosion on material strength, embrittlement, etc., stainless steel is a material that forms a passive film on its surface and is not susceptible to corrosion. The depth of corrosion in air is estimated to be 1m (0.001mm)(2) per year with the maximum of 0.07mm during the period of use, which is a negligible amount of corrosion compared to the thicknesses of the component materials (310mm for a transport container body). Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Fatigue (1) Lifting device Assuming the frequency of handling of the lifting device is 100 times per year, the realistic assumed number of lifting times during the period of use will be 7,000 times. However, the number of lifting times in compliance with the technical criteria is conservatively assumed to be 10,000 times, and the repeat count of 10,000 times covers the assumed number of uses. Based on the above, fatigue is evaluated with the repeat count being conservatively set to confirm that fatigue failure does not occur (A.4.4).
Comparison Table of SAR for Type JRC-80Y-20T before after note (2) Sealing device Assuming the frequency of handling of sealing devices is 4 times per year, the repeat count in 70 years will be 280 times.
However, the repeat count in compliance with the technical criteria is conservatively assumed to be 300 times, and this repeat count of 300 times covers the assumed number of uses.
Based on the above, fatigue is evaluated with the repeat count being conservatively set to confirm that fatigue failure does not occur (A.5.1.4).

Component material Aging factors Evaluation Boron Carbide Heat Although there may be a functional degradation to maintain subcriticality due to microstructural changes caused by exposure to a high temperature environment, the results of the thermal analysis indicate that the maximum temperature during transportation is 223 (B.4.2), which is below the temperature at which this material melts (2450) (B.2). Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Radiation Although there may be a functional degradation to maintain subcriticality due to loss of 10B caused by neutron irradiation, the neutron irradiation dose is 3.25 x 1014 n/cm2 assuming conservatively the period of use of 100 years, the loss of 10B is estimated to be about 0.00013% (E.2.3), which means that the loss of 10B due to neutron irradiation is negligible. Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Chemical changes Although there may be a functional degradation to maintain subcriticality due to corrosion, corrosion does not occur because it is in a sealed space within the basket dividers (stainless steel), and does not come in contact with the outside air. Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.

Component material Aging factors Evaluation Aluminum alloy Heat Although there may be effects on the heat transfer performance due to the microstructural changes caused by exposure to a high temperature environment, the results of the thermal analysis indicate that the maximum temperature during transportation is 223(B.4.2), which is below the temperature at which this material melts (660) (B.2). Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Radiation Although there may be effects on the heat transfer performance due to microstructural changes (embrittlement, etc.) caused by neutron irradiation, the maximum neutron irradiation dose during the period of use is 2.27 x 1014 n/cm2, which is less than the dose of 1021 n/cm2(1) that may cause microstructural changes (embrittlement, etc.). Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Chemical changes Although there may be effects on the heat transfer performance due to corrosion, aluminum alloys form an oxide film on its surface and are not susceptible to corrosion (3). In addition, it is put to use after confirming that there are no abnormalities in its appearance before shipment. Based on the above, there is no need to consider the effect of aging in confirming compliance with the technical criteria.
Comparison Table of SAR for Type JRC-80Y-20T before after note F.3 Aging Considerations in Safety Analysis As described in F.2, the necessity of considering aging effects was evaluated for the component materials of the nuclear fuel package. As a result of the evaluation of aging effects, with regard to the factors of heat, radiation, and chemical changes, under the conditions of use expected during the planned period of use, it was confirmed that there is no need to consider their effects in confirming compliance with the technical criteria. For the lifting device and sealing device, it is necessary to consider aging effects due to fatigue because of repeated stresses. As a result of the evaluations of fatigue of the lifting device and sealing device, considering the conservative repeat count expected during the period of use, it was confirmed that fatigue failure did not occur, and therefore, there was no effect on conformance to the technical criteria.
