ORIGINAL NUCLEAR WATER SYSTEM SAFETY RECORD
Source-original AVC AO-00 editable Word for nuclear water cooling plumbing trade activation 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
Actual trade scope includes water, sewage, domestic plumbing, service lines and auxiliary cooling connections only after approved station classification. Requires contract work order, operator controls, QA level, worker fitness/permits and technical witnesses; no authorisation to modify nuclear safety systems or undertake radiation work.
TECHNICAL TEST AND WATER EVIDENCE
Activate only the authorised scope and approved work package for this particular line, with real facility technical and radiological screening. 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.
