iemens Proposal #SD22007, CR3 Turbine Generator Retrofit 5/3/07 Review Meeting
n Items Continued:
Siemens to provide proposal amendment letter by 05/18/07.
Siemens to provide 1200 MVA generator component evaluation by 06/08/07.
Siemens to address project schedule:
Generator field installation schedule is 69 days, including 48 days for generator stator winding and core iron
replacement working 24 x 7. Siemens to review generator schedule to identify a ten day reduction. If
generator outage schedule does not fit inside revised plant steam generator replacement schedule, then
evaluate stator midsection replacement. Siemens mentioned the possibility of a seed stator frame becoming
available.

Siemens to include the following io the proposal at current price point:
1. Generator main lead bushing replacement.
2. Replace generator H2 seal rings and seal strips on H2 gland, bearing oil catcher and outer oil seal.
3. Generator Ventilation Testing. Add description of requirements.
4. Complete rotor lrain center he
laser alignment and generator fiame foot loading alignment.
5. Replacement of the HP turbine gland steam spillover control valve with larger capacity valve.
6. Machining of the HP turbine steam lead inlet flanges for flexitalic gasket modification.
7. Rebabbit HP turbine and generator bearings due to new rotor journals.
8. New style LP turbine lead free rupture discs.
9. Lowering of the generator leads box to clean and pump sealing groove.
10. A complete new technical manual for the turbine generator (excluding the AEH controller volumes)
and electronic spare parts catalog.
11. Material to support lube oil flush.
12. Seal oil skid modifications to support 75psi generator H2 pressure.
13. The Generator Neutral Transformer will be included in the Siemens electrical evaluation for
1200MVA generator short circuit conditions. Generator protective relay set points will be provided.
14. All LP cylinder alignment and installation features (material and modifications) to install new turbines
are included in proposal.
15. All HP turbine cylinder steam seal surfaces will be checked and machined as necessary.
16. The Generator Neutral Transformer Will be included in the Siemens electrical evaluation for
1200MVA generator short circuit conditions. Generator protective relay set points will also be
provided.
17. AI1 LP cylinder alignment and insrallation features (material and modifications) to install new turbines
are included in proposal.
18. All HP turbine cylinder steam seal surfaces wil be checked and machined as necessary.
Siemens to review the following conceptsrisues:
Project Mananement: PE desires “turnkey” project management with minimal PE support responsibilities.
Siemens to provide millwrights, riggers, welders, pipe fitters, crane operators and winders. TEI may provide
the craft to install the MSRs. Siemens overall project management to include control of additional support
provided by PE (mechanics, electricians, I&C, Mold, insulators, pipe fitters, health physics, laborers,
space attendants, fire watch, etc.). This will eliminate any delays due to ‘‘support requirements by
to discuss this concept with their contracts personnel and provide their position.
