Q98 — CVCS Monitor Tank Release / 2R18 Inoperable
T3 G2.3.6 (3.8)
Given:
- Salem Unit 2 is at 100% power
- A release of 21 CVCS Monitor Tank needs to be performed
- 2R18, Radioactive Liquid Effluent Monitor, was declared inoperable 3 days ago
Which of the following completes both statements?
1. Before performing the liquid radioactive waste release, the (1) authorizes the discharge.
2. Based on the above condition, the ODCM requires that __(2)__
Note: ODCM = Offsite Dose Calculation Manual

2. Based on the above condition, the ODCM requires that __(2)__
Note: ODCM = Offsite Dose Calculation Manual
A. (1) Shift Manager/Control Room Supervisor (2) at least two independent samples of the monitor tank are analyzed prior to the release
B. (1) Shift Manager/Control Room Supervisor (2) continuous surveys of the discharge piping are performed during the release
C. (1) Radiation Protection Manager (2) continuous surveys of the discharge piping are performed during the release
D. (1) Radiation Protection Manager (2) at least two independent samples of the monitor tank are analyzed prior to the release
▶ Show Answer & Explanation
✓ A. Correct. Per the ODCM 3.3.8 Radioactive Liquid Effluent Monitoring Instrumentation, with 2R18 inoperable action 26 applies which requires at least two independent samples are analyzed and at least two technically qualified members of the Facility Staff independently verify the release rate calculations and discharge line valving. Per S2.OP-SO.WL-0001, step 2.5 the SM/CRS authorizes the release.
✗ B. Part 1 is correct. Part 2 is incorrect. Plausible because surveys of piping are performed but for different reason. Incorrect in that the ODCM requires two independent samples analyzed prior to the release which is verified by Chemistry.
✗ C. Part 1 is incorrect. Plausible because the SRO may confuse the responsibility of a radioactive liquid release with a Rad Pro function. Part 2 is incorrect. Plausible because surveys of piping are performed but for different reason. Incorrect in that the ODCM requires two independent samples analyzed prior to the release which is verified by Chemistry.
✗ D. Part 1 is incorrect. Plausible because the SRO may confuse the responsibility of a radioactive liquid release with a Rad Pro function. Part 2 is correct.
