Topic:"Asset Management" in M12745

DESCRIPTION: This project includes the inspection and refurbishment of the Lingan Unit 1 High Pressure (HP) and Intermediate Pressure (IP) turbine components, including the rotor, casings, steam path elements, seals, bearings, and fastener...

AI summary The project involves inspecting and refurbishing critical components of the Lingan Unit 1 steam turbine (HP/IP rotor, casings, seals, etc.) to ensure safe operation. Degradation mechanisms like erosion, creep, and fatigue from high-temperature steam and operational cycling are addressed through this maintenance effort.

Why do this project now? The most recent major inspection of these components (HP and IP nozzles, rotor, inner and outer casings, upper and lower bearings, and thermocouples) was conducted in 2010. By 2026, the HP and IP turbine will have...

AI summary The 2010 inspection of turbine components will reach overhaul thresholds by 2026 due to accumulated operating hours and cycles. Planned maintenance is necessary to mitigate risks of unplanned failure, safety concerns, and regulatory non-compliance.

Why do this project this way? Inspection and refurbishment of HP and IP turbine components within appropriate time intervals, in alignment with the asset management strategy and consistent with industry best practices, is the most cost-eff...

AI summary Refurbishing high-pressure and intermediate-pressure turbine components during the 2026 outage is deemed the most cost-effective approach compared to full replacement, aligning with NS Power's asset management strategy to ensure operational efficiency and reliability while extending asset life.

NON-CONFIDENTIAL 1 Request IR-1: 2 3 Page 1 of the application notes that the Lingan Unit 1 steam turbine consists of a dual flow 4 low pressure (DFLP) and a combined high and intermediate pressure (HIP) turbine that 5 convert steam, suppl...

AI summary The document outlines information requests regarding the refurbishment of Lingan Unit 1, including its current capacity, energy production data, emissions classification, retirement plans, alignment with NS Power's 2030 renewable targets, and actions taken to extend the unit's operational life. The requests also seek details on post-retirement roles and utilization factors.
