These values reflect current understanding of the role of chem-
  • ical. transport, impurity concentr~tions, material selection, corrosion behavior and industry practice for the operation, maintenance and in-tegrity of. steam generator systems. Failure to maintain these limits may reduce long-term Secondary System equipment reliability.

4.1 * -ACTION LEVELS Three action levels for power operation are established and shall be used. to initiate remedial. action when monitored parameters are con-firmed (ie, verified by an additiohal sample and analysi~) to be outside the normal operating value. They are.as follows:

4.Ll Action Level 1

a. Objective Pro~ptly identify and correct the cause of an off.:.normal value
  • without p()wer reduction.
b. Actions:
1. Return parameter to within normal_ value range within seven days following confirmation of excursion.
2. *If parameter is not within normal _vilue range within 1 week

e-PALISADES NUCLEAR PLANT Proc No COP 11 CHEMISTRY OPERATING PROCEDURE Revision 9 Pa_ge 3 of 10 TITLE: SECONDARY .SYSTEM CHEMISTRY 4~ 1.3 Action Level 3

a. Objective*

Prevent rapid steam generator corrosion during continued oper-ation. Plant -shutdown will minimize ingress and eliminate further concentration of harmful impurities.

- b. :Action:

Be in a hot shutdown condition.within twelve hours by initiating a controlled power reduction. Remain in.this operating mode or an operating mode resulting in a lower primary coolant temperature until the normal parameter levels for the existing operating mode can be maintained and normal parameter levels at higher pr~mary coolant temperatures can be expected.

4.2_ LIMITS Limits on the steam generator radiochemistry parameters are specified

  • in Plant Technical Specifications. Corrective actions for these limits 'shall comply with the Technical Specification Requirement_s.

5.0 NORMAL CONTROL AND CORRECTIVE ACTION 5.1 pH 5 .1.1 Normal Control Normal control of secondary cycle pH is maintained by addition_ of morpholine and the ammonia formed by thermal decomposition of hydrazine~ The steam jet air ejector after condenser drain is

'normally routed to waste to reduce ammonia buildup.

5 .1.2 Corrective-Action_

High ~econdary cycle pH can be reduced by reducing morpholine and/or hydrazine feed. Dumping the Plant heating boiler condensate receivers to -waste will also_ help remove volatiles from the system arid lower pH.

NOTE:' This only*applie_s ~hen the heating system is on extracti-on and the. pH problem is' caused by ammonia. -

Increasing steam generator blowdowns is another means of reducing _

system pH. Low pH is generally caused by insufficient chemical feed or large impurity ingress (condenser *air/water inleakage, makeup demineralizer ~alfunction). Chemical feed of morpholine should be increased. to maintain pH limits. Prompt action must b~ taken to terminate any impurity ingress.

conductivity.

5.~~2. Corrective Action High cation conductivity values can be ~owered by reducing impurity i~put and increasing steam generator blowdown. To determine the sou*rce of impurity, sample the following. Analyze the liquid samples for pH, conductivity, sodium and magnesium.

a. Steam Jet Air Ejector Drain
b. Condensate Pump Discharge
c. Condensate Storage Tank
d. North and South Condenser Hotwell Samples

CHEMISTRY OPERATING PROCEDURE Revision 9 Page 5 of 10 TITLE: SECONDARY SYSTEM CHEMISTRY 5.3.2 Corrective Actio~

High steam generator (impurity c*used) ~onductivity may be reduced by increasing steam generator.blowdown and isolating the source of_

impurity *. High conductivity due to excessive additives may be controlled by reducing additive feed rate.

5.4 DISSOLVED OXYGEN 5.4.1 Normal Control Oxygen ingress into the secondary system is controlled by maintaining low levels of condenser ~1r inleakage.

5.4.2 Corrective Action Corrective action to reduce high dissolved oxygen is to locate and isolate air inleakage and increased hydrazine addition *. Care must be exercised with hydrazine addition to assure that hydrazine is not added to excess.

5.5 HYDRAZINE 5.5.1 Normal*Control Normal control of system hydrazine levels is by changing hydrazine feed rates.

5.5.2 Corrective Action Hydrazine conce~trations are adjusted by:varying the hydrazine addition. rai:e.

5.6.1 Normal Control Normal con.trol of steam generator sodium is exercised by controlling makeup quality, controlling condenser inleakage and steam generator blowdow:n.

5.6.2 Corrective Action Confirmed increases in steam generator blowdown sodium levels should lead to the impurity source location sampling listed in Section 5.2.2 of this procedure.

5. 7 . CHLORIDE 5.7.1 Normal Control Normal control of steam generator chl~ride is exercised by' contr6lling makeup quality, controlling condenser inleakage and steam generator blowdown. Steam generator blowdown may be increased to reduce chloride *.level.

5.7.2 Corrective Action Confirmed increases in steam generator blowdown chloride levels should

.lead io the impurity source location sampling listed in Section 5.2.2 of this procedure.

5.8 SILICA 5.8.1. Normal Control

. Normal contr.ol of silica is. by steam generator blowdown and control of makeup water qual_i ty *.

. 5.8.2 .Corrective Action Confirmed increases in steam generator blowdown silica levels should lead to the 'impurity so~rce location sampling listed in Section 5.2.2 of this procedure.

5.9 AIR EJECTOR OFF~GAS FLOW RATE 5.9.1 Normal Control Normal control of condenser air inleakage (Air Ejector Off-Gas Flow Rate) is by locating an4 isolating air inleakage. Air ejector off-gas flow rate should normally be 5-8 cfm or less. Readings greater than or equal to 10 cfm are abnormally high and should result in corrective action.

5.9.2 Corrective Action Use of the freon*leak detector system is recommended for ieak location *

. *Helium *leak detection may also be used for t'eak location". Helium leak detection is more sensitive and will permit ldcati6n of smaller leakage sources.

  • TITLE: SECONDARY SYSTEM CHEMISTRY 5.10 CHEMICAL HIDEOUT AND RETURN 5.10.1 Normal Control Normal control of chemical hideout* and return is _by control of feedwater quality.

5.10.2 Corrective Action Chemical hideout is reduced by maintaining high quality feedwater and steam generator blowdown. Chemical return is reduced by. partial steam generator drain and fill steps and by steam generator blowdown.

5.11 CONDENSATE STORAGE TANK CONTAMINATION LIMITS 5.11.1 Normal Control Normal control of condensate storage t~nk contamination is by control

. of hot well and makeup.quality.*

5.11.2 Corrective Action Co~rectfve acti6n for condensate storage tank contamination is to

~solate the impurity source. and also partial tank drain and fill steps.

5.12 STEAM GENERATOR NITROGEN PURGE 5.12.1* Normal Control

  • During long-term cold shutdown (greater _than three days) a nitrogen pur'ge of the gas space should be established in the steam generators,
  • ih ordei to* minimize the corrosive.effects o~ oxygen. The bottom blowdown lines should normally be used for nitrogen feed to the Steam Generator not on recircul~ti6n. Nitrogen purge is normally secured to the Steam Generator on recirculation. Nitrogen purge with no dete~t able oxygen-present must be established before lowering the Steam

~eneratoi water level (see references i.B and 2~9} such that Steam Generator tubes are uncovered~

NOTE: *Nitrogen purge could be interrupted by maintenance,- in.spectio-n, -eC-c, of the secoridary side of the.steam generators, main steam lines and other components which are normally nitrogen_purged during cold shut-down. Sampling of the gas space may be **suspended during this time.

5.12.2 Corrective Action Rees~ablish nitrogen flow to the Steam Generators as soon as possible.

Low nitrogen/high oxygen concentrations may be due to the following:

a. *Main steam line bladder leak (if.bladder installed).

b.
c. Blocked sample line due to condensation in line.
d. Low nitrogen feed flow.
e. Improper valve lineup.
f. Closed sample valve.
g. Steam Generator manways not properly closed.

. .

h. Secondary side work (ie, sludge lancing, inspections, etc) has contributed oxygen in.the past due to air operated equipment used

~uring these operations.

5.13 SULFATE 5.13.1 Normal Control Normal control of Steam Generator sulfate is exercised by:controlling makeup water quality, controlling condenser leakage, and preventing resin from entering the feedwater and steam gener~tors.

5.13.2 Corrective Action Confirmed increases in sulfate levels. should lead to the °impurity source location sampling listed in Section 5.2.2 of this procedure.

High concentrations of sulfate may be more quickly reduced by performing a Steam Generator drain and ref ill in accordance with References 2.8 and 2.9. A complete drain and refill of the Steam Generators should be-considered when the plant enters a.cold shutdown condition.

5.14 ORGANICS 5.14.1 Normal Control Normal control for organics is accomplished using the Steam. Generator blowdowns by controlling makeup water quality and by maintaining integrity control over various interface systems. Organits intrusion sources are such things as resins (blowdown demin); lubr_icating oils (feedwater pumps) or non-ionic organics introduced through the makeup system.

5.14.2

  • Corrective Action Confirmed increases in Steam. Generator otganics contamination may be reduced by increasing Steam Gene_rator blowdown and isolating the source of impurity.* *

This will minimize low pH corrosion attack of carbon steel or Inconel 600.

3.2 Boric Acid mix tank concentration _must be maintained below 6% to prevent crystallization of the Boric Acid in the feed lines and tank.

3.3 It is essentiai to the success of the conditioning operation that the Borori concentration be inc~eased to 50 ppm as quickly as possible.

3.4 All chemistry parameters must be closely monitored during each conditioning phase.* The s*econdary side chemistry _is to be within the specified guidelines.

4.0 PREREQUISITES 4.1 Plant should be in cold shutdown prior to Boric Acid Soak.

5.0 PROCEDURE 5.1 PHASE I - DRAINING AND FILLING OF STEAM GENERATORS 5.1.1 Steam Generators should be drained and refilled per MSS0-2 and MSS0-3.

Upon initiating the Steam Generator _fill, the oxygen concentration of the fill water should be determined. If greater than 100 ppb oxygen is detected, additional hydrazine should be added to provide a minimum residual in the initial fill of 75 ppm hydrazine *

. chll81-0070jl54-89

Proc. No COP l l Attachment 9 Revi_sion 9

S.l.2 Boric Acid addition should be started upon initiation of the Steam Generator fill via the Slug Feed Chem Add System (T-3S), see Attachment 8. Boric Acid concentration should be increased- to SO ppm.

S.2 PHASE II -_HEATUP (PRIOR.TO HOT.STANDBY)

S.2.1 Start heatup of reactor coolant system. Confirm boron concentration.

Adjust addition rate as _required to maintain approximately SO ppm in the Steam Generator blowdown.

S.2.2. Steam Generator blowdown should continue at the maximum permissible rate, as determined by Plant conditions.

S.2.3 Frequent analysis should be performed to identify the occurrence of any chemical release phenomena. If chemical release is detected, heatup should be suspended* until cleanup is effected. See Table 4i2 for 1 i"mit s. .

S.2.4 Oxygen concentration in the makeup water to the Steam Generators during this period should be identical to that used in the initial fill. See Section S.1.1 S.3 .PHASE III - HEATUP (HOT STANDBY)

S.3.1 Heat up is to *continue until hot standby conditions are reached maintaining SO ppm boron in Steam Generator blowdown.

S.3.2 If necessary, blowdown at maximum rate until chlorides and other impurities are less than Table 4.2 non soak limits _and Table S.l if in Boric Acid Soak.

S.3.3 Maintain hydrazine residual in Steam Generator blowdown per Attachment 4, Table 4.2.

S.4 PHASE IV - POWER ESCALATION S.4.1 Establish 10-20 ppb hydrazine residual in feedwater using normal chem add sys t_em.

NOTE: If pH requirements are not met, the addition of morpholine may be

.necessary.

S.4.2 . Bor~n concentrations sho~ld be maintained at SO ppm by using chem add system. Major Boric Acid addition can be made via the slug feeder if the boron concentration drops below 30 ppm.
