r BLEED STO M SYSTEM 1.0 INTRCDUCTICN 1.1 Svstem Functions The primary purpose of the bleed steam system is to provide steam from six extraction stages of the HP and LP turbines to their respective feedwater heaters. The steam enters the shellside of the feedwater heaters where it heats the feed-water flowing through the tubeside. The heating of the feed-water before entry into the steam generators serves the . cur ose of increasing the efficiency of the. cower.clant cycle. e In addition, the bleed steam system provides heating steam to the first stage reheaters of the moisture separator-reheaters 'i3 in the main and rehea t s team system and also supplies steam to the auxiliary s team system. The bleed steam system has an interface with the following systems. (Drawing numbers refer to Eurns & Roe flow diagrams): Main and Reheat Steam System (Dwg. No. 2002) A uxiliary S team Sys tem (Dwg. No. 2004) Feedwater Heater Drains System (Dwg. No. 2009) Instrument and Service Air System (Dwg. Nc. 2012) 1.2 Summary Description of th e Svstem (Refer to B&R Dwg. No. 2003, Rev. 13) Bleed steam is extracted from the 3rd and 8th stages of the HP turbine and the 10th, lith, 13th and 14th stages of both LP turbines. There are two feedwater heaters which receive bleed sLc?n from each extraction stage and are identified e -l~ a

i after the extraction stage from which they receive their heating steam. The feedwater heaters are arranged in two parallel trains to provide six stages of feedwater heating. The 14th stage feedwater heaters, which are the lowest prec-sure heaters, are located in the neck of each condenser. The 8th stage is the exhaust stage of the HP turbine. Each external bleed steam line has a ccmbination stop-check valve to prevent water induction or reverse flow of steam to the turbine. The 3rd stage bleed steam lines, however, have separate stop and check valves because of the high pressure and temperature condition. Each bleed steam line has a motor operated drain valve located between the turbine and the stop-check valve. In addition to supplying steam to the 3rd stage feedwater heaters FW-JEA and 63, the 3rd stage high pressure turbine extraction su) plies heating steam to the first stage reheaters of the four moisture separa tor-reheaters. The reheaters reheat the HP turbine exhaust steam prior to admission to the two double flow icw pressure tur' ines and the steam gen-r erator feed pump turbines. Excess bleed steam from the first stage reheaters ficws to the 8th stage feedwater heaters thrcugh a connection to the heater drain tank vent lines. Refer to the Feedwater Heater Drains System Description, Index No. 7. Excess main s team from the second stage reheaters ficws to the 3rd stage feedwater heaters thrcugh a connemti-n to the heater bleed steam supply line. / R -E

The auxiliary steam system is supplied with steam frcm the 8th stage (HP turbine exhaust) extraction of the HP turbine. Refer to the Auxiliary Steam System Description, Index No. 3. The 3rd staga feedwater heaters FW-J-6A, 63 are considered high pressure hea ters. All other feedwater heaters are considered low pressure heaters. Motor operated valves are provided to divert a portien of the 10th stage extraction steam to each of the two con-denser hotwells to deaerate the condensate at plant operating loads of 4076 and below. 1.3 Svstem Design Recuirements The bleed steam system is a conventional sys tem. The ecuip-ment comprising the system, including piping and valves, .j is of commercial cuality and the seismic design classification is class II. The seismic Class II equipment is designed for Zone 1 loads. The piping within the bleed steam system is designed, fabri-cated, inspected and erected in accordance with ANSI 331.1.C. Power Piping, while valves are in accordance with applicable ANSI pc >ssure-temperature ra tin s. The feedwater heater sizes are based on the maximum expected turbine rating (not guaranteed) which corresponds to the maximum primary system power ra ting of 2 788 Mwt. The maximum calculated-not guaranteed turbine hea t balanc e is included as Figure 1. Two identical parallel feedwa ter tra ins utilizing bleed steam from six turbi:ie extraction points are provided lhO M M

to handle the above rating in the most economical manner. Feedwater heater shell design pressures are determined by add-ing 15 percent to the maximum expected turbine rating heat balance stage pressure, then using the next highast 25 psi value, except' that no heater shell is designed for less than 50 psig. Shell side design temperatures are determi ad at the temperature corresponding to the design pressure en the turbine expansion line. Under emergency conditions of one heatertrain out of service, each remaining heater is capable of handling additional extraction steam resultant when the tubeside feedwater ficw is increased temporarily by 50 percent. Tubeside design conditions art as discussed in the Feedwater and Condensate System Description, Index No. 4A. The mechanical design and constructica of the feedwacer heaters are in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII and are stamped with the applicable ASME Ccde symbol. Sizing of the bleed steam lines was acccmplished in order to comply with the pressure drop requirements of the maximum calculated - not guaranteed turbine heat balance. Ccabination stop-check valves are located in the turb ine external extracticn lines to the low pressure feedwater heaters. Due to the higher pressure and temperature condition of the 3 rd stage HP turbine extraction s team, separate check and stop valves are utilized in the 3rd stage bleed steam lines. The purpose of the check valves is to prevent water damage to the turbine if heater drains back up frcm the feedwater heaters, and to prevent overspeed of the turbine with a decrease in Icad or turbine trip, which can cause a ^ ]/\\ t e

reverse flow of steam from the feedwater heaters to the . turbine. 2.0 DETA ILED DFSCRIPTICN OF SYSTD1 2.1 Ccmconents 2.1.1 Feedwater Heaters; FW-J-1A, 13, 2A, 23, 3A, 33, 4A, 43, SA, SB, EA, 6B mhe feedwate.- heaters are described in the Feedwater Heater Drains System Description Index No. 7 and the Feedwater and Condensate System Description, Index No. 4A. 2.1.2 Moisture Separator - Reheaters-MO-T-LA, 13, 2A, 23 For a description of the moisture separator-reheaters, refer to the Feedwater Heater Drains System Description, Index No. 7 and the applicabl'e Westinghouse manual (1.00). ~~ 2.1.3 Mad or Svstem Valves 3rd Stace Bleed Steam Stoo Valves EX-V2 2A, 22B An electric motor operated 18" gate valve with 400 lb.

A single pushbutton contrcl switch (EX-FHS-3242) and a single set of indicating lights are provided on the Turbine Auxiliaries Monitoring Panel 17 for all the drain valves. ..i 2.2 Instruments, controls, ' A larms and Protective Devices 2.2.1 Instruments All heaters have pressure and temperature indication in the Control Rocm as listed in Table 1. 2.2.2 Bleed Steam Stoo-Check valve Control The bleed steam stop-check valves (separate stop and check valves in the 3rd stage bleed steam line) are autcmatically or remote manually controlled through the I and C Logic System. Refer to B&R Instrumenta tion and Control Schematic drawing No. 3090, Sheets 64, 64A, 6 5 and 6 5A. When a high-high level occurs in a feedwater heater drain cooler, the stop check valve is a atomatically closed in the bleed steam line to the feedwater heater. When a turbine i 3, \\ J _9_

tri.p occurs, the stop-check valves in all the bleed steam lines are automatically closed. Each valve may be individually closed by pushbutten control from Panel 17. When the valve is being closed, the air cylinder is first vented and the spring in the air cylinder pushes the check valve disc to the closed position. When the check valve closed limit switch is actuated, the electric motor operator is automatically energized which turns a stem down to the disc to seat the disc and hold it cl sed. When the valve is being opened, the electric motor operator is energized first. When the stem is fully withdrawn from the valve disc, the electric motor operator open linit switch is actuated. Air pressure is then autcmatically applied to the air cylinder which forces the piston in the air cylinder to its top position with the closing spring cc= pressed. The valve disc is free to swing open or closed as with any ordinary check valve. The 3rd stage bleed steam check valve op2 rates in the same manner a s the other bleed steam check valves except that instead of the motor operator having a stem to seat the check valve disc, a separate motor operated shue.off gate valve is used. Af ter a stop-check valve is autcmatically closed because of heater drain cooler high-high level, it can only be opened by manually resetting a relay using a Panel 17 pushbutton after the level has been restored to normal. After a turbine trip, all the secp-chech valves are automatically cpened when \\1-in turbine trip is reset..

2.2.3 Turbine Bleed Steam Drain Valve Control The turbine bleed steam drain valves are automatically or remote manually controlled through the I and C Logic System. Refer to B&R Instrumentation and Control Schematic drawing No. 3090, sheets 64, 64A, 65 and 65A. When a high-high level occurs in a feedwater heater drain cooler, the drain valve in the bleed steam line to the feed-water heater is automatically opened. When a turbine trip occurs, the drain valves in all the bleed steam lines are automatically opened. A single pushbutton control switch EX-FHS-3242 is provided on the Turbine Auxiliaries Monitoring Panel 17 to close the drain valves. 2.2.4 Safetv Val.vos -.m. Four 6" x 8" pressure relief va.bes Ex-RlA, 13, 2A, 23 are provided on the four bleed steam lines to the 13th stage feedwater hea ters FW-J-2A, 23. Auxil'.ary s team is supplied to the 13th stage feedwater heaters through a connection with the bleed steam lines to heat the feedwater during s tartup. The valves are set to open at 50 psig to protect the heaters and bleed steam piping from overpressur-t the event the pressure control valves in the auxiliary steam system fail. 2.2.5 A la rms and comouter Incuts Alarms and Computer inputs are listed in Table 2.

3.0 PRINCIPA L MCO ES OF OPEPATICN 3.1 startup The blaed steam line stop-check valves are closed and the turbine bleed steam drain valves are open as a result of the last turbine trip during plant shutdown. A f ter actua ting the turbine trip reset, the bleed steam stop-check valves are automatically opened. The 13th stage bleed steam stop-check valves EX-VllA, 113, 16A and 16B are closed frcm Panel 17 so tnat the auxiliary steam supply valves As-VEA, 63, 6C and 6D may be opened in order to heat the feedwater. The turbine bleed steam drain valves are left open. The deaerating steam supply valves which supply 10th stage bleed steam to the condenser hotwell are opened. As steam is admitted to the turbine and turbine load is increased, bleed steam flow from the turbine is increased. A f ter the bleed steam lines are warmed up, the bleed steam line drain velves are closed. When plant load is increased to the point where the bleed steam can heat the feedwater to the required temperature, the a uxiliary steam to the 13th stage feedwater heaters is shut off and the 13th stage bleed steam stop-check valves are opened. At approximately 40% plant lead, the dea era ting s team supply valves are closed. 3.2 Normal Coeration Above 40% plant load, the bleed steam " rem each turbine bleed s tage flows through the stop-check valves to the respective feedwater heater. The 3rd stage bleed steam supply also provides heating steam to the first stage reheater of the mo is ture separator-reheaters and the 6th stLge bleed steam I) k h

supply can provide steam to the auxiliary steam system. .e. 3.3 Shutdown As turbine lead is decreased, the bleed steam ficw frcm the turbine decreases in proportion to turbine load. A t about 40% plant lead, the deaerating steam supply valves are opened to supply deaerating steam to the condenser hotwells. When turbine load is decreased to 0% and the turbine is tripped, the bleed steam stop-check valves are automatically closed and the turbine bleed steam drain valves are automatically opened. 3.4 Scecial or Infrecuent operation 3.4.1 Bleed Steam Stco-Check Valve Closed r.: : ~. If a high-high feedwater heater level occurs, the bleed steam stop-check valve will auccmatically close. If the level returns to normal, the valve can be opened manually by depressing the Panel 17 reset pushbutton. If the level is not restored to normal, the reason for the high-high level nust be found and the problem corrected. 3.4.2 ffedaater Heater Train cut of Service If a high pressure feedwater heater or low pressure feedwater heater train needs to be taken cut of service, the bleed steam stop-check valv;s to the feedwater heaters being taken out of service are individually closed. Io ('312 3.5 Emercencv s The two emergency conditions which af fect the kl eed steam syster are a feedwater heater high-high level or a turbine trip. When

either of these events cccur, the bleed steam secp-check valves and drain valves function autcmatically. 4.0 HAZA RDS AND PR ECA L"FICNS The bleed steam stop-check valves play an important part in preventing water induction to the turbine and also overspeed of the turbine when it is tripped. Their function is auto-matically controlled during plant operation. They are to be periodically tested by using the hand operated air testing valve at each stop-check valve. ~, "'2 4 9 1 =
