General scope: Design, manufacture and supply of a screw conveyor (100 NB) per Necsa specification ENS-MES-SPE-0055 and drawing ENS-MES-DWG-0004 (project C81009). The conveyor includes mild steel construction (with possible material advancement), stainless steel elbows/universal joints (100 NB, SCH 40S, ASTM A182 F304L/304L, ASME B16.11), and a motor flange (100 NB SCH 40 ANSI B16.5 Class 150 SS, T.B.C.). Referenced P&IDs: ENS-FDP-PID-24001 to 24005. PTFE filter destruction is noted. Drawing revisions: 1.0 (10/09/2024) and 2.0 (06/06/2026) by D. Luhleko. Document is confidential and proprietary to Necsa.

• Nuclear industry experience and compliance with South African nuclear regulations (NNR requirements).
• Proven track record in manufacturing pressure equipment or conveyors.
• Ability to provide material certificates and inspection/test records.
• Security clearance may be required for access to nuclear facility.
