reheat and four pass tube bundles shall be included in the Seller‘s scope of supply.
MSR moisture separation and tube bundles should be designed to optimize the
turbine steam cycle to achieve the best performance within the existing shell
envelope.
Existing nozzle configuration and piping should be reused to the extent possible.
The MSR shall be designed in accordance with Electric Power Research Institute
(EPRI) NP-3692 “Procurement and Operation Considerations for Moisture
Separator Reheaters.“
439 SS tube material shall be specified.
MSR instrumentation package shall be included.
INSTRUMENTATION AND CONTROLS
The turbine AEH control system is expected to be reused. Refer to Section 1.7.5 of
the Bid Specification for more information.
The turbine supervisory instrument system is a Bently Nevada 3300 system and is
expected to be reused. Refer to the Bid Specification for more information.
Pickup mounting details will be provided by the Owner to support retrofit design.
Refer to the Bid Specification, page 12 for more information.
Generator rotor flux probes will be reused or replaced. Refer to page 12 of the Bid
Specification for more information.
Recommend new generator monitoring systems (rotor flux monitor, stator end turn
vibration monitor, stator partial discharge monitor, etc.) as appropriate.
Fumish all electrical components and associated auxiliary equipment required to
support:
0 the turbine replacement
0 the MSR replacement, and
0 generator modifications.
Fumish a MSR instrumentation package, and
Fumish a generator instrumentation package.
Evaluate existing electrical and control systems and interfaces to verify existing
capabilities and compatibility, specifically:
0 Turbine speed control system (AEH Electro-Hydraulic Control System).
0 Auxiliary instrumentation and controls.
Design equipment to ensure that all of the interfacing systems, structures, and
components shall be reused, if possible, and shall operate with minimal
modification of the systems.
