- 1. Introduction The purpose of this analysis is to evaluate, using numerical calculations, the temperature of the FCC packaging under Normal Conditions of Transport (NCT)
- 2. Calculations - approach and methods 2.1. Software The calculations are carried out using the I-DEAS software interfaced with the thermal module TMG <1>.
2.2. Model mesh & geometry The model used in this study is a 2D thermal model, representing a section of the uninterrupted section of the FCC4 packaging shell and internal fittings. The model details the plates, the resin of the frame and the doors, the fuel rod claddings, the guide tubes and the pellets, as per the models presented in Appendix 2.2-1.
As in Appendix 2.2-1, the sizes of the air inlet openings in the cavity of the internal fittings are, respectively, 7mm in the upper section and 5 mm in the lower.
The 17x17 rod array is represented in the calculation model. The geometry and meshing of the internal fittings and17x17 fuel rod array is presented in figure 1.
The geometry of the shell is modelled in accordance with drawing <2> in Appendix 1.4-1 of Chapter 1.4. As per this drawing, the outer radius of the upper shell is mm, the outer radius of the lower shell is mm. The calculation model also represents the air between the internal fittings and the packaging shell.
2.3. Materials The characteristics of the materials used for the packaging, and the air, are given in tableau 1.
2.4. Power levels The fresh UO2 pellets do not emit any power.
2.5. Heat exchanges 2.5.1. Conduction The conductive exchanges within the materials are calculated directly by the code <1>,
using the thermal conductivity of each material, given in Table tableau 1.
The gap between the claddings and the pellets is calculated using the geometric characteristics of the 17x17 array, taken from Chapter 2.2-1, and listed in the table below:
dC: External rod diameter (mm) e: Thickness of claddings (mm) dP: Pellet diameter (mm)
Array pitch (mm) 12.6 The radial gap (noted j) between the claddings and the pellets is calculated using the following equation:

The Contact Resistance value (Rc) is deduced using the equation:
Where helium = W.m-1.K-1. from tableau 1 Therefore, the contact resistance for a 17x17 array is as follows:
. /
2.5.2. Convection The air surrounding the packaging shell is not represented. The heat exchanges, by convection, are modelled, using a coefficient of exchange: h = 1.4T1/3 W.m-2.K-1. The calculation is based upon correlations taken from <3>.
2.5.3. Radiation The radiative exchanges between the claddings and the plates of the internal fittings, and between the outer surface of the internal fittings and the shell of the packaging, are directly calculated using the code <1>. They are modelled using radiative boxes. The emissivity levels of the various materials are given in Table 1.
Radiative exchanges between the outer surfaces of the shell and the ambient air are modelled using a view factor of 1. The shell is covered, inside and out, with a paint coating, the emissivity of which is (conservative value from Appendix 2.2-1).
2.5.4. Ambient The temperature of the ambient air is assumed to be 38°C.
2.5.5. Exposure to sunlight The calculation is carried out for transient operating conditions with 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of sunlight exposure per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. (regulatory exposure over 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> followed by zero exposure for the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />). The exposure is defined below, as per Table 13 of
<4>:
The solar flux received by the upper (curved) section of the packaging shell is 400 W/m².
The solar flux received by the vertical walls and lower (curved) section of the packaging shell is 200 W/m².
The density of the solar flux received by a given surface is , where is the surface absorptivity and E the regulatory sunlight.
The absorptivity is conservatively considered as being equal to 1 (See tableau 1)
