TITLE OF THE INVENTION INDUSTRIAL TECHNIQUE ABSTRACT OF THE DISCLOSURE A typical embodiment of the invention provides a combination feedwater and "cooldown" water spray head that is centrally disposed in the lower portion of a nuclear power plant steam drum. This structure not only discharges the feedwater in the hottest part of the steam drum, but also increases the time required for the feedwater to reach the steam drum shell, thereby further increasing the feedwater temperature before it contacts the shell sur- face, thus reducing thermal shock to the steam drum structure.
