class pyne.transmute.chainsolve.Transmuter(t=0.0, phi=0.0, temp=300.0, tol=1e-07, rxs=None, log=None, *args, **kwargs)[source]¶

A class for transmuting materials using an ALARA-like chain solver.

Parameters

tfloat: Transmutations time [sec].
phifloat or array of floats: Neutron flux vector [n/cm^2/sec]. Currently this must either be a scalar or match the group structure of EAF.
tempfloat, optional: Temperature [K] of material, defaults to 300.0.
tolfloat: Tolerance level for chain truncation.
rxsset of ints or strs: Reaction ids or names to use in transmutation that produce well-defined children. This set should thus not include fission. If None, then the reactions from EAF are used.
logfile-like or None: The log file object should be written. A None imples the log is not desired.
argstuple, optional: Other arguments ignored for compatibility with other Transmuters.
kwargsdict, optional: Other keyword arguments ignored for compatibility with other Transmuters.

transmute(self, x, t=None, phi=None, tol=None, log=None, \*args, \*\*kwargs)[source]¶

Transmutes a material into its daughters.

Parameters

xMaterial or similar: Input material for transmutation.
tfloat: Transmutations time [sec].
phifloat or array of floats: Neutron flux vector [n/cm^2/sec]. Currently this must either be a scalar or match the group structure of EAF.
tolfloat: Tolerance level for chain truncation.
logfile-like or None: The log file object should be written. A None imples the log is not desired.
