2019 JPM IP-k — Conduct an Authorized Waste Gas Release

⚠️ DRAFT
JPM IP-k — Conduct an Authorized Waste Gas Release In-Plant (RCA) | RO/SRO | 071 A4.26 (3.1/3.9)

Time-Critical: No
Alternate Path: No
Estimated Time: 25 minutes

Initial Conditions:
- Both Salem Units are operating at 100% power.
- 21 Waste Gas Decay Tank is in Standby at 15 psig.
- 22 Waste Gas Decay Tank is in Holdup at 90 psig.
- 23 Waste Gas Decay Tank is O/S at 15 psig.
- 24 Waste Gas Decay Tank is O/S at 15 psig.
- 2R41 Plant Vent radiation monitor is Operable.
- Plant vent flow rate and sample flow rate monitors are Operable.

Initiating Cue:
- CRS directs you to PERFORM a release of 22 Waste Gas Decay Tank IAW S2.OP-SO.WG-0009, Discharge of 22 Gas Decay Tank to Plant Vent, starting at Step 5.2.11.
- Section 5.1 and Steps 5.2.1 through 5.2.10 are complete.
- You have the Tag Release for 22WG31.
Task Standard:
1. Performs a Radiological Waste Gas release IAW S2.OP-SO.WG-0009.
2. Terminates the Waste Gas release as directed by procedure.
▶ Show Critical Steps & Key Actions
Step Critical Element Standard
5.2.11.A ENSURE 22 GDT is NOT in service Verifies that 22 WGDT is NOT in service.
5.2.11.B ENSURE 22 GDT is NOT selected for "Standby" Verifies 22 GDT is NOT selected for Standby.
5.2.11.C RECORD 22 GDT "Initial Pressure" (PIS2037) on Attachment 3 Records 22 GDT pressure as 90 psig from PIS2037.
5.2.11.D.1 * TURN 2WG41 Waste Gas Vent Valve Flow Bias fully counterclockwise until indicator <0% (NOTE: 2HIC-14 must be set to <0% or 2WG41 will NOT latch) Simulates turning Flow Bias knob fully COUNTER-CLOCKWISE until indicator is <0%. Must set bias to <0% before opening to latch and set the valve.
5.2.11.D.2 * POSITION 2WG41 Selector Switch to OPEN AND RELEASE to AUTO position (spring return) Simulates positioning selector switch to OPEN, then releases to AUTO.
5.2.11.D.3 * TURN 2WG41 Waste Gas Vent Valve Flow Bias clockwise until indicator >= 100% Simulates turning Flow Bias CLOCKWISE until indicator reads >= 100%. 2WG41 will not fully open until flow bias is 100%.
5.2.11.D.4 ENSURE with Unit 2 Control Room that 2WG41 has lost CLOSED indication AND audible alarm received Calls Control Room to verify 2WG41 has lost closed indication and audible alarm received.
5.2.11.D.5 * TURN 2WG41 Waste Gas Vent Valve Flow Bias fully counterclockwise until indicator <0% Simulates turning Flow Bias fully COUNTER-CLOCKWISE until indicator <0%.
5.2.11.D.6 ENSURE with Unit 2 Control Room that 2WG41 has CLOSED indication Calls Control Room to verify 2WG41 has CLOSED indication.
5.2.11.D.7 * POSITION 2WG41 Selector Switch to CLOSE Simulates positioning 2WG41 selector switch to CLOSE.
5.2.11.E PERFORM IV of 2WG41 Flow Bias position, RECORD on Attachment 1, Section 2.0 Requests IV on 2WG41 Waste Gas Vent Valve Flow Bias position.
5.2.11.F * OPEN 22WG31 Simulates rotating valve counter-clockwise to open 22WG31.
5.2.11.G * Slowly OPEN 22WG34 Simulates slowly rotating counter-clockwise to open 22WG34.
5.2.11.H RECORD IV of 22 GDT discharge valves 22WG31 and 22WG34 on Attachment 1, Section 3.0, prior to commencing 22 GDT release Requests IV of 22 GDT discharge valves prior to commencing release.
5.2.12.A * POSITION 2WG41 Selector Switch to OPEN AND RELEASE to AUTO (spring return) — commence release Simulates positioning 2WG41 selector switch to OPEN and releasing to AUTO to commence the release.
5.2.12.B * SLOWLY SET 2WG41 Waste Gas Vent Valve Flow Bias to <= 100% Simulates adjusting 2WG41 Flow Bias to <= 100%. Records release data on Attachment 2, Section 5.1. 2WG38 pressure on 2PL8678 reads 7.8 psig.
5.2.13.A CALCULATE 22 GDT Average Release Rate every 10 minutes on Attachment 3 Operator reads step and determines no action at this time until 10 minutes has elapsed. Continues on.
5.2.13.B RECORD Meteorological Data in Attachment 2, Section 5.2 Records MET Data: Wind Speed 5.8 MPH at El 33 ft, Wind Direction 290 degrees at El 33 ft, Delta T (33 ft - 33 ft) = 0 degrees C.
5.2.13.D IF pressure downstream of 2WG38 is >8.0 psig OR 2WG41 CLOSES, THEN TERMINATE release Operator reads step and determines none of these conditions are present. Marks N/A and continues.
Term * 22 WGDT pressure reaches 10 psig — TURN 2WG41 Flow Bias fully counterclockwise until indicator <= 0% Operator turns 2WG41 Flow Bias fully counter-clockwise until indicator reads 0%.
Term * PLACE 2WG41-SWT to CLOSED position Operator places 2WG41-SWT to the closed position.
Term * CLOSE 22WG34 Operator closes 22WG34.
Key Decision Point:
The latch-and-set sequence (Step 5.2.11.D) is the most complex portion — the applicant must correctly manipulate 2WG41 Flow Bias and Selector Switch in the proper order (bias to <0%, open to auto, bias to 100%, verify lost closed indication, bias back to <0%, verify closed, then position selector to CLOSE). For the actual release (Step 5.2.12), the applicant opens 2WG41 to AUTO and sets flow bias to <= 100%. Upon reaching 10 psig tank pressure, the release is terminated by reducing flow bias to <0%, closing 2WG41-SWT, and closing 22WG34. This is procedurally identical to the 2023 JPM IP-k except for the tank number (22 GDT vs 21 GDT) and the associated procedure (S2.OP-SO.WG-0009 vs S2.OP-SO.WG-0008).
