Which vertical port is used for experimentation?

• A. The third vertical port is used for the Sb-Be source.
• B. The third vertical port is sealed and unused.
• C. Third vertical port is used for experimentation.
• D. The third vertical port houses the Pu-Be source.

Answer: (C)

Ports in a reactor are assigned specific roles, with one dedicated for experimentation so researchers can insert detectors and experimental hardware while keeping proper shielding and alignment with the core. The statement that the third vertical port is used for experimentation matches that intended use, making it the best description of its function. The other possibilities describe alternate roles—being sealed and unused or housing a specific neutron source—that would not support the ongoing experimental work that this port is meant to enable. So, designating the third vertical port for experimentation correctly reflects its purpose.
