IV. Plant Su ort R1 Chemistry Controls R1.1 Secondar Chemistr Pro ram a.
Ins ection Sco e 84750 Implementation of the secondary chemistry program and secondary system control parameters for 1995 and 1996 were reviewed to determine effectiveness.
This review included the control, monitoring, and trends of secondary chemistry parameters (sodium, sulfate, molar ratio, and feedwater iron) in the secondary water systems.
This data were compared to the licensee's goals and the industry's chemistry performance index criteria to determine the licensee's performance.
b.
Observations and Findin s The licensee's secondary chemistry control limits and action levels were established in accordance with the Electric Power Research Institute Pressurized Water Reactor Secondary Water Chemistry Guidelines, Revision 3. The steam generator chemistry was controlled by limiting contaminate additions and maintaining chemical additions (molar ratio control) within specified limits. The intrusion of contaminates into the steam generators was maintained to a minimum by continuous blowdown for removal of concentrated contaminates resulting from system operation.
Molar ratio control was maintained by the controlled addition of ammonium chloride.
Since 1994, site chemistry instituted many initiatives to improve secondary chemistry performance.
The addition of ammonium chloride into the steam generator secondary system to enhance molar ratio control, steam generator cleaning, electrochemical potential testing, blowdown flow optimization, hideout return data evaluation, and downpower recommendations to enhance hideout return cleanup were changes instituted to improve secondary chemistry.
To ensure that the data were trended and an action plan developed for continuous improvement, site chemistry instituted the chemistry program plan.
Although the same performance goals applied to all units, each unit was somewhat unique in its secondary chemistry performance.
This was partly due to unit specific conditions and partly due to differing secondary control schemes tailored to optimize conditions for each uni During the time period between January 1995 and December 1996, Unit-1 secondary chemistry data showed secondary chemistry parameters were generally within specification and approaching or achieving chemistry program plan goals with the exception of sulfate and iron.
Excessive iron transport remained an issue while a low pH was maintained to support condensate polisher operation.
Unit-1 was also plagued with condenser inleakage and condensate polisher problems.
During the time period between January 1995 and December 1996, Unit-2 secondary chemistry data showed that all secondary chemistry parameters were within specification and generally achieved chemistry program plan goals and showed an improving trend during the time period.
Exceptions were sulfate, condensate dissolved oxygen, and feedwater iron.
During the shutdown and coast down prior to the outage in January 1996 chemistry program plan goals were not achieved.
During the time period between January 1995 and December 1996, Unit-3 secondary chemistry data showed that with exception of sulfate, sodium, and iron, secondary chemistry parameters were within specification and approaching or achieving chemistry program plan goals.
During the outage recovery period in December 1995, the sodium, sulfate and iron chemistry parameters were excessively above the target values, and the unit experienced a deviation from the target molar ratio operating range.
Upon initiation of condensate polisher operation, with reduced pH after February 1996, the secondary chemistry parameter performance degraded severely.
On May 6, the inspector observed a Unit-1 senior chemistry technician monitor the daily readings from the secondary chemistry on-line instruments and data recorders in the secondary laboratory and turbine building laboratory.
Data from the on-line ion chromatographs, sodium analyzers, pH meters, and cation conductivity meters were recorded on continuous chart recorders'and transmitted directly to a chemistry data management computer (data view) in the secondary chemistry laboratory for contiriuous monitoring and trending.
The inspector determined that the secondary chemistry control was highly dependent on the continuous on-line instrument monitoring of the secondary chemistry parameters to maintain steam generator molar ratio chemistry within established limits. The licensee verified the on-line instrument data by comparison to weekly grab sample analytical results.
In 1997 the licensee established a new chemistry performance index for secondary chemistry.
The licensee's chemistry index was more conservative than the Institute of Nuclear Power Operations (INPO) chemistry performance index because the individual secondary chemistry impurity divisors in the numerical equation were the licensee's secondary chemistry concentration goals rather than the 1995 INPO
i
-5-median concentration values for the secondary chemistry parameters.
The inspector determined that the licensee's current secondary chemistry performance index values (calculated using the INPO chemistry index divisor values) were 1.03 for Unit-1, 1.00 for Unit-2, and 1.13 for Unit-3. The INPO chemistry performance index median value was 1.07.
c.
Conclusions An improved secondary water chemistry program was implemented.
The licensee's secondary chemistry performance index values compared well with the industry's secondary chemistry performance median value.

b.
Observations and Findin s The licensee's primary chemistry control limits and action levels were established in accordance with the Electric Power Research Institute Pressurized Water Reactor Primary Water Chemistry Guidelines, Revision 3. The reactor coolant chemistry program specifications were established to minimize corrosive species such as oxygen, chloride, fluoride, and controlling pH.
Primary system chemistry control performance for the time period January 1995 through April 1997 resulted in excellent operational primary chemistry control as shown by the pH and dissolved hydrogen analytical results.
The reactor coolant system pH was maintained in the desired operating range (6.9 - 7.15) by coordinating the boron and lithium concentrations to maintain an alkaline pH to minimize crud transport.
Dissolved hydrogen control in the three units'eactor coolant systems was good and met chemistry program objectives in the operating range of 25-50 cc/Kg of reactor coolant.
Eight dissolved hydrogen out-of-specification conditions occurred at the three units, and there were only two occurrences when the pH control was greater than 0.05 pH units from optimum values between January 1995 and April 1997.
All dissolved hydrogen deviations were corrected within 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> Reactor coolant system pH and boron, lithium, and dissolved hydrogen concentrations were consistently maintained within the optimum operating ranges per Electric Power Research Institute guidelines and met primary chemistry program goals.
The reactor coolant system fluoride, chloride, and dissolved oxygen concentrations were maintained within the optimum operating concentrations with minimal occurrences of out-of-specification conditions.
The inspector observed a senior chemistry technician collect a depressurized liquid sample, gas stripped pressurized liquid sample, and gas sample from the Unit-2 reactor coolant system on May 6, 1997, and perform a dissolved oxygen analysis and dissolved hydrogen analysis.
The technician followed the sampling and analytical procedures methodically and used good self-checking and radiological work practices while sampling and analyzing the samples.
All aspects of the reactor coolant system sampling and analyses were performed in accordance with approved procedures.
The inspector determined that the sampling and analyses of each unit's primary system chemistry and radiochemistry parameters met Technical Specification requirements.
