JPM SRO-A4 — Authorize a Radioactive Gas Release Form
Admin | SRO | G2.3.6 (3.8)
Location: Classroom (Administrative)
Time-Critical: No
Alternate Path: No
Estimated Time: 10 minutes
Initial Conditions:
- 13 WGDT is in holdup in preparation for performing a gas release via the Plant Vent
- Chemistry has performed all required sampling and authorized the gas release
- The release procedure, S1.OP-SO.WG-0010, Discharge of 13 Gas Decay Tank to Plant Vent, has just been handed to you by the Unit 1 Plant Operator, who informs you the release is ready for CRS approval
- All procedure sections are complete up to Step 5.2.9
Initiating Cue:
- You are the Unit 1 Control Room Supervisor (CRS)
- REVIEW all completed sections of the procedure for accuracy and completeness
- DETERMINE the following:
a. Can you authorize the gas release?
b. If No release is authorized; identify ALL issues to be corrected

b. If No release is authorized; identify ALL issues to be corrected
Task Standard:
1. Review Gas Release and identify that:
a. Pre-Release verification has not been performed in Attachment 1, Section 1.0
b. Calculated Maximum Allowable Release Rate is not > 32 SCFM
c. CRS does not authorize the gas release
1. Review Gas Release and identify that:
a. Pre-Release verification has not been performed in Attachment 1, Section 1.0
b. Calculated Maximum Allowable Release Rate is not > 32 SCFM
c. CRS does not authorize the gas release
▶ Show Critical Steps & Key Actions
| Step | Critical Element | Standard |
|---|---|---|
| 1 | Review marked up S1.OP-SO.WG-0010 procedure | Operator reviews the completed procedure sections for accuracy and completeness |
| 2 * | Identify that PRE RELEASE VERIFICATION in Attachment 1, Section 1.0 has NOT been performed prior to step 5.2.8 | The first error: Pre-Release verification has not been performed in Attachment 1, Section 1.0, prior to the procedure being given to the CRS for release approval |
| 3 * | Identify that Maximum Allowable Release Rate of 32 SCFM recorded in Step 3.4 and 4.1 is not > 32 SCFM | The second error: per NOTE in Step 3.4, tanks with a calculated maximum allowable release rate of <= 32 SCFM cannot be released. The recorded value of 32 SCFM is NOT > 32 SCFM. |
| 4 * | Determine CRS does NOT authorize the gas release | Operator determines the release cannot be authorized due to both identified discrepancies and records findings |
Key Decision Point:
Steps 2 and 3 are the discriminating steps. The applicant must catch two errors in the completed procedure: (1) The Pre-Release Verification in Attachment 1, Section 1.0 was skipped — this step must be completed before the CRS reviews for release authorization. (2) The Maximum Allowable Release Rate recorded as 32 SCFM is insufficient — per the NOTE in Step 3.4, the rate must be GREATER THAN 32 SCFM (not equal to) for the release to proceed. A common trap is that the applicant finds the first error and stops reviewing, assuming one deficiency is sufficient to deny authorization. The examiner cue specifically directs continued review of the entire procedure.
