ORIGINAL NUCLEAR WATER SYSTEM SAFETY RECORD
Source-original AVC AO-TB-01 editable Word for nuclear flooding & water release toolbox talk at nuclear generating facilities. Plumbing and cooling tasks may affect equipment cooling, flooding barriers, water quality, electrical plant or redundant process trains. This original contractor record supports technical controls under an approved station work package; it does not itself authorise system isolation, line opening or restart.
WHEN THIS PRINTED FORM IS REQUIRED
Identify the actual nuclear facility, unit, authorised work area, line/valve/cooling system, current engineering drawing, work order, permit and QA or safety-significance class. Confirm nominated plant owner and competent pipework or water-services personnel. Assess possible backfeed, stored head, overflow, marine fouling, system cross-connections, wastewater, adjacent electrical systems and emergency drainage interfaces before any intrusion.
SOURCE-ORIGINAL PRINTED CRITERIA
Eight source workface topics: drain and bund vulnerabilities, approved line-opening and monitoring, adjacent live electrical equipment, potentially safety-significant cooling and redundant trains, stored head/syphon/backflow, trapped gases/marine deposits, high-pressure wash constraints, STOP unexpected flooding/pressure/odour. Crew attendance.
TECHNICAL TEST AND WATER EVIDENCE
Brief all eight actual water/flooding toolbox topics with the real work crew; record questions and worker attendance. Retain leak/pressure test values and calibrated instrument references, water sample results, cleaning or foreign-material exclusion records, environmental disposal and corrective NCR reports, as relevant.
FLOOD AND HEAT-SINK SYSTEM BOUNDARIES
The licence holder determines whether the work touches the ultimate heat sink, emergency or redundant cooling, safety-classified water systems or protected flooding compartments. A contractor may not remove flood doors, create unintended cross-connections, defeat level detection or drain equipment without operator instructions. Unexpected water migration, unknown pressure, fouling deposits or threatened live electrical plant requires immediate STOP and station notification.
