All units are given in SI, such that the input temperature is Kelvin, and the output units of the thermal conductivity $var element = document.getElementById("moose-equation-95d6cd5a-a508-4194-980b-afd5497a893e");katex.render("k", element, {displayMode:false,throwOnError:false});$ are W/m $var element = document.getElementById("moose-equation-bd56208e-32fe-48f9-a0c7-c15856b3779c");katex.render("\\cdot", element, {displayMode:false,throwOnError:false});$ K, the output units of the isobaric specific heat capacity $var element = document.getElementById("moose-equation-7a2429fa-de9e-416f-bc65-0cb8d5596246");katex.render("C_p", element, {displayMode:false,throwOnError:false});$ are J/kg $var element = document.getElementById("moose-equation-2a228497-8d6e-4092-af10-b0784b2ddff3");katex.render("\\cdot", element, {displayMode:false,throwOnError:false});$ K, and the output units of the density $var element = document.getElementById("moose-equation-ca9dfdd8-0c43-4757-ad5c-301f0d33cf1d");katex.render("\\rho", element, {displayMode:false,throwOnError:false});$ are kg/m $var element = document.getElementById("moose-equation-884f4111-5aef-4350-a9ba-afd474ae8b28");katex.render("^3", element, {displayMode:false,throwOnError:false});$ .

Isobaric specific heat is calculated from Agency. (2008) as

$var element = document.getElementById("moose-equation-6ec16af1-5d67-4185-934d-93fd878f0683");katex.render("C_p= 239.7 - 5.068\\times 10^{-3} * T + 1.7604\\times10^{-5} * T^2 - 3488100 * T^{-2}", element, {displayMode:true,throwOnError:false});$

This is valid for estimating isobaric specific heat over 298 K $var element = document.getElementById("moose-equation-ae519d13-3fb1-449c-a7b7-4f66e1758223");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ T $var element = document.getElementById("moose-equation-32f49c8b-1d7b-4b57-b2d5-e9774719d29d");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ 2838 K

Thermal conductivity is calculated from Vasudevamurthy and Nelson (2022) as:

For 323 K $var element = document.getElementById("moose-equation-c4569619-0ec3-4e15-88eb-789d2e3a9272");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ T $var element = document.getElementById("moose-equation-953c87e8-bea0-4081-8128-6f3ed064b371");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ 923 K $var element = document.getElementById("moose-equation-a84955ad-e5e4-4775-8cb0-cd47c245b780");katex.render("k=21.7-3.04\\times 10^{-3} * T+3.61\\times 10^{-6} * T^2", element, {displayMode:true,throwOnError:false});$

And for 924 K $var element = document.getElementById("moose-equation-96d0ea9b-fa97-47f1-9570-c373c92ded76");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ T $var element = document.getElementById("moose-equation-9a4a8e65-f44b-411c-8926-c0f508fdeb7e");katex.render("\\le", element, {displayMode:false,throwOnError:false});$ 2573 K, the thermal conductivity is: $var element = document.getElementById("moose-equation-fb633e08-594f-479e-a1dd-782fdd914c97");katex.render("k=20.2+1.48\\times 10^{-3} T", element, {displayMode:true,throwOnError:false});$

The density is assumed constant. A default value is provided Vasudevamurthy and Nelson (2022) as

$var element = document.getElementById("moose-equation-a4c9819e-a664-429a-a7cc-d8bffe44dbd3");katex.render("\\rho= 13824.7", element, {displayMode:true,throwOnError:false});$

Like many other refractory and transition metal carbides these compounds exist in both hypo- and hyper-stoichiometric compositions which results in significant variations in physical, thermal, and mechanical properties. This manuscript surveys both historic and recent literature to compile important properties data mainly as a function of temperature and carbon content to support fuel performance modeling. Expressions and fits for such properties are also suggested when allowed by complete data sets. The manuscript also attempts to highlight gaps and discrepancies in the reported data to assist the nuclear fuels community identify key areas that may require further attention in terms of future research and development.",
