# pyrk.materials.sfrmetal module¶

class pyrk.materials.sfrmetal.SFRMetal(name='sfrmetal')[source]

Bases: materials.material.Material

This class represents SFR Metal fuel. It inherits from the material class and possesses attributes intrinsic to SFR metal fuel, as reported in T. Sofu, A review of inherent safety characteristics of metal alloy sfrmetal-cooled fast reactor fuel against postulated accidents

density()[source]

SFRMetal density as a funciton of T. [kg/m^3]

specific_heat_capacity()[source]

Specific heat capacity of SFRMetal [J/kg/K] actually depends on temperature pretty strongly.

TODO, Issue #4 The CODATA equation gives the relation:

$\begin{split}c_p &= 1.6582 - 8.4790\times10^{-4}T\\ &+ 4.4541\times10^{-7}T^2 - 2992.6T^{-2}\end{split}$

Below is a constant estimate of sfrmetal cp at temperatures around 400C based on table 1.1-5 in http://www.ne.anl.gov/eda/ANL-RE-95-2.pdf
