These pictures were forwarded to me with the following short explanation:

The photos show a pipe failure in a fossil plant hot reheat steam line. The hot reheat line is the line that passes steam back to the turbine after its first pass through the turbine and return to the boiler for additional heat. The pressure in this line is significantly reduced from main steam pressures (possibly 700 psi, down from 2500 psi) as much of the steam energy has been used in the high pressure stages of the turbine. Reheat steam temperature is about 1000 degrees F, the same as main steam.
