Q98 — Locked High Radiation Area IV Waiver
G2.3.7 (3.6)
Given:
• An NEO has signed onto a RWP to perform an Independent Verification (IV) on a manual gate valve located inside a Locked High Radiation Area (LHRA)
• RP estimates that the operator would receive a dose of 15 mrem while performing the IV
Which ONE of the following completes the statements below?
In accordance with RP-AA-460 (CONTROLS FOR HIGH AND VERY HIGH RADIATION AREAS), an LHRA has a MINIMUM dose rate of _(1)_ mrem/hr @ 30 cm.
In accordance with OP-AA-108-101-1002 (COMPONENT CONFIGURATION CONTROL) and based on the estimated dose of 15 mrem to perform the IV, the Shift Manager is _(2)_ to waive the "Hands On" IV of the manual gate valve.

B. (1) 100 (2) permitted
C. (1) 1000 (2) NOT permitted
D. (1) 1000 (2) permitted
▶ Show Answer & Explanation
✓ D. Correct. For Part 1 and in accordance with RP-AA-460 (CONTROLS FOR HIGH AND VERY HIGH RADIATION AREAS), an LHRA has a MINIMUM dose rate of 1000 mrem/hr @ 30 cm. For Part 2 and in accordance with OP-AA-108-101-1002 (COMPONENT CONFIGURATION CONTROL) and based on the estimated dose of 15 mrem to perform the IV, the Shift Manager is permitted to waive the "Hands On" IV of the manual gate valve.
✗ A. Incorrect but plausible. For Part 1, 100 mrem/hr is the limit for posting the area as a High Radiation Area.
✗ B. Incorrect but plausible. For Part 1, 100 mrem/hr is the limit for posting the area as a High Radiation Area.
✗ C. Incorrect but plausible. Part 1 is correct. For Part 2, the candidate could incorrectly conclude that for an estimated dose of 15 mrem, the Shift Manager can not waive the "Hands On" IV of the manual gate valve.
