S2.OP-ST.CVC-0010 — Borated Water Sources
DRAFT — Reconstructed from exam materials
Purpose
Surveillance procedure to verify borated water sources (RWST and BASTs) meet Tech Spec 3.1.2.6 requirements for level, temperature, and boron concentration. Performed in Modes 1-4.
Key Actions / Information
Attachment 2 — Borated Water Sources Data (Modes 1-4)
| Parameter | Instrument | Acceptance Criteria | Source |
|---|---|---|---|
| RWST Level | 2LT960, 2LT961, 2LT962, 2LT963 | 364500 to 400000 gals (40.5 ft to 41.9 ft) | TS 3.1.2.6 |
| RWST Temp | T0650A | ≥35 F | TS 3.1.2.6 |
| RWST Conc | Chemistry | ≥2300 and ≤2500 ppm | TS 3.1.2.6 |
| 21/22 BAST Vol | 2LI106, 2LI102 | IAW TS 3.1.2.6.a/.b and Figure 3.1-2 | TS 3.1.2.6 |
| 21/22 BAST Temp | 2TI107, 2TI103 | ≥63 F | TS 3.1.2.6 |
| 21/22 BAST Conc | Chemistry | IAW TS 3.1.2.6.a/.b and Figure 3.1-2 | TS 3.1.2.6 |
Notes
- If one BAST is the borated water source, then level and concentration requirements must be maintained in the acceptable operation region of Figure 3.1-2. If two BASTs are the borated water source, then combined volumes are used to satisfy TS 3.1.2.6.a.
- For tank capacity data, refer to S2.OP-TM.ZZ-0002(Q).
Acceptance Criteria (Step 5.3)
- Step 5.3.1: Surveillance is considered satisfactory when Attachments 2 and 3 (as applicable) are complete with components listed meeting Acceptance Criteria stated in each Attachment.
JPM — 2019 RO-A2
Borated Water Sources surveillance with narrow-margin UNSAT results. Combined BAST level: 48% + 48% = 96%. Per TS 3.1.2.6 Figure 3.1-2, required level at 6650 ppm concentration is >96.5% — volume is UNSAT. Similarly, BAST concentration of 6650 ppm is just below the required ~6675 ppm from Figure 3.1-2 at 96% level — also UNSAT. RWST parameters (level 41.4 ft, temp 70 F, conc 2350 ppm) and BAST temperatures (100 F, 98.1 F) are all SAT. Overall surveillance is UNSAT.
