The PULSTAR reactor is situated along Engineering Row in the main campus, surrounded by Mann Hall, Daniels, Polk Hall, and a park. The reactor has a dedicated building and uses one cooling tower; it releases water vapor when the reactor is at high power. This building is not a Containment building, but it maintains a negative pressure to prevent any release of radioactive material. The reactor can be operated up to a power of 100 kW on natural circulation, or 1 Megawatt (MW) with the use of pumps.
