System Description

1 The S/G's are once through vertical tube to shell heat exchangers I which produce superheated steam at constant pressure. The shell, outside of the tubes and tube sheets form the boundary of the S/G secondary side (steam producing region). The pressurized water side has reactor coolant entering the steam generator through the inlet y' g nozzle in the upper head, flows through the tubes into the lower Q plenum and out the two nozzles to the reactor coolant pumps. Feedwater enters through 32 spray nozzles, flows down the annulus between the circular baffles (surrounding the tube bundle) and shell (see Enclosure D). As feedwater is sprayed into the lower annulus, it is heated to saturation temperature by mixing with and condensing steam from the bleed port between the upper and lower baffles. This prevents thermal shock to the shell and excessive tube-to-shell l temperature differentials. Water at saturation temperature flows through the adjustable orifice plates between the baffle and the shell, through ports at the lower i end of the baffle and into the tube bundle at the lower tube sheet. [ Boiling begins Omnediately upon contact with the hot generating tubes and steam increases in stese quality as it flows upward and becomes i superheated in the upper section of the S/G. Steam leaves the steam generator steam annulus in two 26" headers which feed their respective 36" sain stema line. S/G 1-1 is the source of steam for main steam line 1 while S/G 1-2 supplies main steam line 2. Six inch connections are then made to the auxiliary feedpump turbines (AFPT) with main steam line 1 supplying AFPT 1-1 i and main steam line 2 supplying AFFT 1-2. Next, nine main steam safety valves are connected to each main steam line. t i i i 4 ,._ w ,,--,.,...c.. -,.,n- ,,.,,w-n,-,, ,.ev,n., y,- -,. --.-,.--,,.,,-,ng,,--..m,_nw.m.., ..-,-sm-.c-.

2 SP 1106.24.3 ~s The main steam safety valve setpoints and capacities are as follows: Valve Valve Setpoint Capacity 3 SP17A8 SP17B8 1100 psig 845,759 lb/hr SP17A9 SP17B9 1100 psig 845,759 lb/hr SP17A3 SP17B3 1070 psig 845,759 lb/hr SP17A4 SP17B4 1070 psig 845,759 lb/hr SP17A5 SP17B5 1090 psig 845,759 lb/hr SP17A6 SP17B6 1090 psig 583,574 lb/hr SP17A7 SP17B7 1090 psig 583,574 lb/hr 3 SP17Al SP17B1 1050 psig 845,759 lb/br SP17A2 SP17B2 1050 psig 845,759 lb/hr Downstream of the main steam safety valves, an 8" connection is made for the atmospheric vent valve on each main steam line. As steam progresses down the main steam line, it next passes through the main steam isolation valves and then the main steam non-return valves. The main steam isolation valves are air operated, balanced disc stop valves set in opposition to the normal flow direction and serve to limit an excessive resetor coolant system cooldown rate and resultant reactivity insertion following a main steam line break downstream of the valve. The main steam non-return valves are air operated, swing disc stop check valves which are provided to prevent reverse flow of steam out of a rupture upstream of their position. Downstream of the non-return valves, main steam line 1 has a 6" connection to Main Feed Pump Turbine (MFPT) 1-1, then a ten inch i connection to the auxiliary steam system 235 psig main steam reducing station. Next, main steam line 1 supplies second stage reheat steam to MSR 1-1 through a 10" header. Finally, 24" connections are made to turbine stop valves 3 and 4. Main steam line 1, then reduces down to a 12" header which leads to three turbine bypass valves connections. The 6" turbine bypass valves are used during Main Steam System operation to pass excess steam to the condenser during plant transients and during plant heatup and cooldown to control the heatup and cooldown rates. After main steam line 2 leaves its non-return valve, a 6 inch connection to Main Feed Pump Turbine 1-2 is made. Main steam line 2 then passes steam to turbine stop valves 1 and 2 through two 24 inch connections. The line to turbine stop valve 1 also bas a 4 inch connection to the Gland Steam Seal System. Downstream of the connection to the turbine stop valve, main steam line 2 reduces to a 12" header. This header then supplies second stage reheat steam for MSR 1-2 through a 10" connection and finally feeds the three turbine bypass valves connected at its end. 2. PRECAUTIONS AND LIMITATIONS 2.1 The ICS has interlocks which prevent the turbine bypass valves from passing flow to the condenser when condenser pressure is

j l 3 SP 1106.24.4 greater than 10" HgA and/or total circulating water flow is less than 210 KGPM. During these conditions, steam pressure control will be provided by the atomspheric vent valves. 2.2 Turbine bypass valve desuperheating water from the condensate system must be spraying from the desuperheating spray headers whenever the turbine bypass valves are in service. 2.3 Before transferring the turbine bypass valve H/A selector station to "AUT0", set the pressure setpoint at the position corresponding to existing pressure to prevent a sudden maneuvering of the turbine bypass valves after the transfer. 2.4 The turbine bypass valves provide main line pressure control at the indicated pressure for the following conditions: Condition Turbine Bypass Control Pressure Reactor Trip

  • Setpoint +145 psig Turbine Trip Setpoint

+0 Unit Load Demand >15% Setpoint +50 psig

  • Turbine bypass valve pressure setpoint 2.5 Even if the turbine bypass valves H/A selector stations are on

" RAND", the turbine bypass valves will open when S/G exit ('S pressure (taps located on the 26" S/G discharge headers) exceeds \\,/ 1050 psig for that main steam line. If the turbine bypass valves fail to open due to the conditione of Step 2.1, the atmospheric vent valves will automatically provide pressure control at 1050 psig. 2.6 The minimum required instrument air supply is 85 psig for use with the turbine bypass valve high speed valve actuator. If 4 air pressure decreases to 75 psig, the turbine bypass valves will close. If air pressure is restored, they will return to normal operation. 6l 2.7 On a loss of electrical signal (124 VDC) or a loss of power (118VAC) to a turbine bypass valve electro-to pneumatic (E/P) converter, that turbine bypass valve will fail closed. (TS 2.8 Each steam generator shall be OPERABLE with a water level 3.4.5) between 18 and 348 inches during HOT SHUTDOWN, HOT STANDBY, STARTUP, and POWER OPERATION. With one or more steam generators inoperable due to steam generator tube imperfections, restore the inoperable generator (s) to OPERABLE status prior to increasing Tavg above 200'T. With one or more steam generators inoperable due to the water level being outside the limits, be in at least HOT STANDBY within six hours and in COLD SHVTDOWN within the next 30 hours.

4 SP 1106.24.3 s (TS 2.9 All main steam line code safety valves shall be OPERABLE for HOT 3.7.1.1) STANDBY, STARTUP and POWER OPERATION. With one or more main steam line code safety valves inoperable, operation in HOT STANDBY, STARTUP and PokT.R OPERATION may proceed provided that within four hours either the inoperable valve is restored to OPERABLE status or the High Flux Trip setpoint is reduced per Tabla 3.7-1 (of Technical Specifications); otherwise be in at least HOT STANDBY within the next six hours and in COLD SHUTDOWN within the following 30 hours. The provisions of Specification 3.0.4 are not applicable. (TS 2.10 Each main steam line isolation valve shall be OPERABLE during 3.7.1.6) HOT STANDBY, STARTUP and POWER OPERATION. While in P0kIR OPERATION, with one main steam line isolation valve inoperable, POWER OPERAIION may continue provided that the inoperable valve is either restored to OPERABLE status or closed within four hours. Otherwise, be in HOT SHUTDOWN within the next 12 hours. While in HOT STANDBY or STARTUP with one main steam line isolation valve inoperable, subsequent operation in HOT STANDBY, STARTUP or POWER OPERATION may proceed provided:

a. the inoperable isolation valve is maintained closed. Otherwise, be in HOT SHJTDOWN within the next 12 hours,
b. The provisions of Specification
  • 3.0.4 are not applicable.

2.11 Main steam isolation valves MS100 and MS101 aust have their trip logic blocked for operation below 600 psig. On a depressurization, the trip logic should be blocked between 650 and 600 psig. + (TS 2.12 The temperature of the secondary coolant in the steam generators 3.7.2.1) shall be >l10*F when the pressure of the secondary coolant in the steam generator is >237 psig. This applies at all times. With the requirements of the above specification not satisfied:

a. reduce the steam generator pressure to <237 psig within 30 minutes, and
b. perform an engineering evaluation to determine the effect of overpressurization on the structural integrity of the steam generator.

Determine that the steam generator remains acceptable for continued operation prior to increasing its pressure above 237 psig. 2.13 The discharge of the S/G drain header can be routed to either the condenser or the Miscellaneous Waste Drain Tank. Prior to discharge, Ches & HP personnel should determine where to drain and, if to the Miscellaneous Waste Drain Tank, that adequate volume is available. 2.14 FW minimum bypass flow of >32 gpa should be maintained when RCS 3 temperature is >180*F. This flow must be maintained until 57. power is exceeded. FW temperature must be maintained greater than 90*F. This prevents thermal shocking of the S/G nozzles due to an excessive temperature differential across the nozzles and precludes hot-cold cycling of the nozzles. See Enclosure A.

I i 4 5 SP 1106.24.3 fm 3 2.15 The low temperature limits of the main and auxiliary feedwater nozzles are 90'F and 40*F, respectively, at hot shutdown limits. 3l 2.16 Deleted 2.17 S/G feedwater chemistry will be within the 10mits specified by i PP 1101.04, Operational Chemical Control Limits. F 2.18 When a vacuum is drawn in the S/G, the reference legs for level I instrumentation may flash giving erroneous level indication. S ] 2.19 A S/G level of 100% on the operate range (388 inches full range) will allow water to enter the steam annulus through the operate and startup range level penetration through the steam annulus baffle. At 416 inches on full range instrumentation the water level will be at the bottom of the steam outlet nozzle. Extreme 4 I caution must be used during startup and hot shutdown and cooldown to avoid approaching these levels. J 3.

MAIN STEAM SYSTEM HEATUP General

Description:

During initial stages of plant heatup, S/G level is established between 97 to 99% operate range with level being regulated by adjusting feedwater flow and the S/G lower tube sheet drains. The turbine bypass valves are then opened to the condenser to draw a vacuum in the S/G which will flash the hot water in the S/G to steam, warning the upper portion of the S/G shell. Initially, the S/G steam arnulus 4 drains and all sain steam line drains are open and are closed as stese becomes superheated up to their taps. NOTE: The actual procedural steps to be executed for Main Steam System Startup are contained in Station Startup Procedure, i PP 1102.02. [ 5. HOT SNUTDOWN AND C00LDOWN j General Description Prior to hot shutdown, the turbine is taken off line and reactor power is reduced to zero. A hot shutdown condition exists when the reactor is subcritical by at least 1%Ak/k and Tavs is at or greater than 525'F. 4l As the Main Steam System is cooled down, 870 psig sain steam line pressure will be maintained by the turbine bypass valves. FW sinimum bypass flow of 132 spa should be maintained when RCS temperature is 1180*F. After reactor power is reduced to zero, the turbine bypass valves will be used to reduce Tavs to $32*F by controlling the turbine bypass valve pressure setpoint. As main steam line pressure is reduced and steam conditions become saturated, the S/G steam annulus drain valves and the main steas line drains are then opened. Once Tava drops to 280*F, the Decay Heat Removal System will be used to cooldown the RCS and the turbine bypass valves will be positioned 5% open to cooldown the S/G shells. Once RCS cold les temperature reaches 200'F, the main steam isolation valves will be shut and the S/G's will be flooded to their upper tube sheet.

i 7 SP 1106.24.4 NOTE: The actual procedural steps to be executed for Main Steam System hot shutdown and cooldown are contained in Station Shutdown and Cooldown Procedure, PP 1102.04. 6. ABNORMAI. OPERATION i 6.1 In the event of a sudden large decrease in turbine generator load, observe that the turbine bypass valves or atmospheric vent valves open to maintain main steam line pressure below 920 psig. If the load decrease is due to a malfunction of the turbine EHC, take Lamediate action to repair and/or tune up the EHC. 4 6.2 On a turbine trip without a reactor trip (<20% RTP), verify that the turbine bypass valves are maintaining main steam line pressure at 870 psig. 6.3 On a reactor trip, observe that the turbine bypass valves or atmospheric vent valves are maintaining the main steam line pressure at 1015 psig. Main steam line pressure may rise above 1015 psig immediately following the reactor trip due to the decreased heat load on the steam generator resulting from turbine trip. 6.4 If the turbine bypass valve H/A selector stations are in " HAND" or "AUT0" and S/G pressure increases to 1050 psig, verify that c-the turbine bypass valves or atmospheric vent valves maintain j q main steam line pressure at or below 1050 psig. 7. ISOI.ATION OF T1?RBINE BYPASS VAI.VE Isolation of one turbine bypass valve requires isolation of all turbine bypass valves on the respective main steam line. The numbers not in parenthesis refer to equipment for the isolation of main steam line 1 turbine bypass valves while the numbers in parenthesis refer to main steam line 2 turbine bypass valves. 71 Place the H/A selector station for turbine bypass valves SP 13Bl. SP 13B2 and SP 13B3 (SP 13A1, SP 13A2, and SP 13A3) on "EAND" to prevent unexpected stroking of the valve. NOTE: If the turbine bypass valva.s were being used for pressure control, place the H/A selector statica for atmospheric vent valve ICS 11B (ICS 11A) on "HLND" and control manually Main steam line pressure is indicated by computer points P481 (HPT SIDE 1 IN PRESS) and P482 (HPT SIDE 2 IN PRESS). 7.2 Close turbine bypass valves SP13B1, SP13D2, and SP13B3 (SP13A1, SP13A2 and SP13A3). b a
