CRE TM ATS Reviewer #2 (HP Warming to Rub Check)

A. HP Turbine Warming - most effective means of accomplishing this pre-warming is causing pressurization, the HP turbine with steam, thus raising the temperature to the saturation temperature of the steam or higher. The pressure normally specified is __ to __ksc (g)

The pressurization should be used whenever the first stage shell inner surface is below ___ C. For higher metal temperature, the pre-warming is not necessary.

HP  Turbine Warming check the MSP should be?

HP Turbine Warming MST should be?

HP Turbine Warming  RHP should be?

___ and ___  be in service (HP Turbine Warming)

GOV is execute, LLM is set in -2% and Governor Normal Set  is?

while the Auxiliary  Steam Temperature  (200-267C)  and pressure is

Also check Condenser Pressure, Normal Limits is __ ksc

TCS will Open HP Turbine warming Valve (MV-AS1011) Note: Maximum position at initial opening of the valve is __ % opening

TCS will Close CV (B) below seat drain valve from 100% to 20% opening after the 30s that the AS1011 reached the opening of _%

During HP turbine warming, steam goes from HP to ILP through Packing No. 2 thus, turbine speed increases. Take note of increase in rpm. Recommended turbine speed during HP turbine warming is  ____ rpm. Monitor maximum speed reached

When HP Turbine Metal Temperature reaches at  ___C. The holding operation should be carried out. See FIGURE 2 for the required holding time.

Eccentricity of 0.06 mm is noticeable after turning gear engaged. Wait for one to two minutes until eccentricity reaches its normal value of ___ to ___mm at turbine speed of 3 rpm.

B. SERVICE MS & RH FOR TEMPERATURE CONTROL,MS DESUP = > ___ MSF RH DESUP = > 69MSF NOTE: Transfer operation complete
