Which component is listed as likely to collect crud in a reactor coolant system?

• A. Low point drain
• B. Orifice
• C. Valve
• D. Filter

Answer: (D)

In a reactor coolant system, solids and corrosion products—often called crud—travel with the coolant. A filter is placed in the loop specifically to trap these solid particles as the coolant flows through it. Over time the filter collects debris, which is why it’s the component most likely to accumulate crud and require inspection or replacement to maintain proper flow and heat transfer. The other options serve different functions: a low point drain is for draining maintenance water from the system and isn’t designed to continuously capture debris; an orifice is a flow-restriction device and doesn’t collect solids; a valve can become a site where debris might settle but it isn’t a dedicated collection device.
