2023 Q99 — Containment Radiation CFST / FRCE-3

⚠️ DRAFT
Q99 — Containment Radiation CFST / FRCE-3 T3 G2.4.2 (4.6)
Given:
- The STA is monitoring Critical Safety Function Status trees

Which of the following completes the statement?

If Containment Radiation Monitors (1) exceeds 2 R/HR, the CRS (2) 2-EOP-FRCE-3, Response to High Containment Radiation Level.
A. (1) R10A/B (2) must GO TO
B. (1) R44A/B (2) must GO TO
C. (1) R44A/B (2) may elect to GO TO
D. (1) R10A/B (2) may elect to GO TO
▶ Show Answer & Explanation
✓ C. Correct. Per 2-EOP-CFST-1, for containment environment, the R44A and R44B radiation monitors are used to determine whether entry into 2-EOP-FRCE-3 is required if radiation levels are above 2R/HR. FRCE-3 is a yellow path procedure, not RO knowledge, and the SRO must apply the rules of usage for FRPs to determine how the procedure is performed. Yellow path procedures are optional.
✗ A. Part 1 and 2 are incorrect.
✗ B. Part 1 is correct. Part 2 is incorrect. Plausible because if the SRO believes a Red or Purple path exists, then entry into the FRP is required. Incorrect in that a yellow path exists and entry is optional.
✗ D. Part 1 is incorrect. Plausible because the R10A/B radiation monitors are located inside containment. Incorrect in that the R44A/B are the high range radiation monitors used in the CFSTs. Part 2 is correct.
