Chemical thermodynamics of Cs and Te fission product interactions in irradiated LMFBR mixed-oxide fuel pins

“…The magnitude of this corrosion has been assessed for three types of FBR steel cladding [1,2], namely advanced austenitic [3][4][5][6][7], high strength ferritic/martensitic [8], and oxide dispersion strengthened [9][10][11][12] steels.…”

“…Tellurium is corrosive in nature and can exist in various chemical states in irradiated fuel. It can cause embrittlement of clad [8]. The possibility of interaction of Te with fuel material and fission products to form both metallic and oxide phases cannot be ruled out.…”

“…During the burn up of MOX fuel, the highly corrosive and reactive volatile fission product tellurium is generated. It populates the fuel-clad gap and causes embrittlement of the clad material (SS316) [1][2][3]. Data on the thermodynamic stability of the compounds of tellurium with the clad components, viz.…”

The standard Gibbs energy of formation of iron tellurate, Fe 2 TeO 6 (s), was determined by measuring the vapour pressure of TeO 2 (g) over the phase mixture Fe 2 TeO 6 (s) ? Fe 2 O 3 (s) in the temperature range of 1103-1203 K by employing a thermogravimetry-based transpiration technique. The temperature dependence of the vapour pressure of TeO 2 (g) generated by the incongruent vapourization reaction Fe 2 TeO 6 ðsÞ ! Fe 2 O 3 ðsÞ þ TeO 2 ðgÞ þ 1=2O 2 ðgÞ obtained from this study could be represented as log (p (TeO 2 (g)/Pa ± 0.03) = 17.53-19,836/T (1103-1203 K). The temperature dependence of the Gibbs energy of formation of Fe 2 TeO 6 (s) derived from the above expression could be represented as {DG f o (Fe 2 TeO 6 , (s)) (kJ mol -1 ) ± 6.0} = -1276.3 ? 0.507 T (1103-1203 K). An inverse drop calorimeter was used for measuring the enthalpy increments of Fe 2 TeO 6 (s) for the first time in the temperature range of 483-1083 K. The thermodynamic functions, viz. heat capacity, entropy and Gibbs energy functions of Fe 2 TeO 6 (s), were derived from the experimentally measured enthalpy increment values. A mean value of -1318.1 ± 0.9 kJ mol -1 was obtained for DH o f;298 K ðFe 2 TeO 6 ðsÞÞ by third-law analysis of vapour pressure data.
