- Attended exit. interview Exit Interview The ' inspection scope and findings were summarized on June 12, 1987, with those persons indicated in paragraph 1 above. The inspector described the areas inspected and discussed in detail the inspection findings. ' No dissenting comments were received from the licensee. The licensee did not identify as proprietary any of the materials provided to or reviewed by i the inspector during this inspectio . Licensee Action on Previous Enforcement Matters This subject was not addressed in the inspectio . Plant Chemistry (79701) ,
This inspection was the fourth in a series of assessments of the licensee's capability to maintain the integrity of the primary coolant )
pressure boundary - specifically the integrity of the steam generator j tubes. As noted in the last inspection report concerning this subject, J the continuing formation of cracks in these tubes in both units indicated that degradation was occurring through mechanical erosion and several corrosion mechanisms.

the current refueling outage of Unit i revealed additional indications of defects in tubes at the top of the tube sheets, at the levels of tube support plates, and in the U-bend region In an effort to eliminate a small primary to secondary leak and to prevent failure of other degraded ,
tubes, 118 tubes had been . plugged in the three steam generators. The !
total number of tubes now plugged represents 6.17 percent, 5.25 percent, and 7.99 percent of all tubes in Steam Generators A, B, and C of this uni All three steam generators of Unit I were also sludge lanced during the current outage, and a total of 3500 pounds of metal oxides (iron and i copper) had been remove i Through an audit of chemistry data and discussions with cognizant personnel from the plant and corporate staffs, the inspectors established that the licensee was addressing deterioration of steam generator-tubes and wastage of carbon steel components of the steam and power conversion ;
system (i.e. , the secondary water system) in a number of ways; e.g.,
' tightening', repairing, or replacing individual components, expanding inservice surveillance programs, and upgrading chemistry diagnostic and control capabilities. These actions are summarized below, and each action has been evaluated as to its potential for mitigating ongoing tube and pipe degradation as well enhancing long-term protection against deterioration from corrosion mechanisms, Plant Design and Operation ,
The inspectors reviewed the effectiveness of each of the principal )
components of the secondary water systems relative to either j prevention of ingress or removal of contaminants that could cause )
corrosion of the steam generator tube (1) Main Condenser - Through an audit of chemistry data taken during i 1987 the inspectors observed that the quality of water in the !
condenser hotwells had been maintained at high levels in both units; e.g., cation conductivity 0.10-0.12 umhos/cm, specific j conductivity 3 to 5 umhos/cm, sodium at non-detectable levels, l and dissolved oxygen 3 to 8 ppb. (conductivity measurements of samples from the hotwell and steam generator blowdown were considered to be biased on the high side because of the presene i of boric acid that was being continuously added to the steam generator water to control denting of steam generator tubes.)
Water inleakage through the condenser had been essentially eliminated, as indicated by the sodium content of the hotwell water, since che last inspection in March 198 This was achieved by throttling down the flow of condenser cooling water during colder months so that the differential temperature in the condenser was maintained at approximately 15F. This action prevented vibration of the condenser tubes, with accompanying leaks at tube-tube sheet interfaces, as had occurred in previous

-(3) Water Treatment Plant As the result of continuing problems with the original water tredmont plants, especially the flash evaporators, the licensee had thur down these plants for major overhaul. f The licensee had contracted for a portable water treatment system to provide demineralized water for condensate makeup and other plant uses while the oldtr plants were out of servic ~
The inspectors reviewed the operation of the portable system through a walkdown of the modular components and discussions with the contract operator and licensee personne '
The plant Nonsisted of interchangeable water purification un'its that used both domineralizing (iron exchange resin beds) and reverse osmosis mechanisms to produce water of very high purity (specific conductivity of 0.058 umho) and low oxygen content (2 a ppb) at a rate of 200 gpm per unit - four units were available !

, 's s As ncted in previous inspection reports the inspectors observed !
that the
! licensee was continuing to experience problems with the '
powdered-resin demineralizers used for condensate cleanu '
Full-flow polishing had been performed satisfactorily during unit startups but, subsequently, only one of the five beds were retained in tuse - to help control the concentration of ammonia (i.e., to control pH). The principal deficiency associated with the demineralizers continued to be " throw" of chloride ions and i resin pdyticle More than half of these particles are less than 15 microns in size. In an effort to reduce this type of contamination of the feedwater the licensee was investigating
,
different. types of filter elements and ion-exchange resin "
Even Uith minimum polishing the licensee had been able to maintain high quality feedwater (i.e., cation conductivity of s 0.14 to 0.16 umho/cm and no detectable dissolved oxygen). The inspectors were not able to assess the extent to which soluble and solid species of copper and iron were being transported into
'
the 'feeovater because of insufficient data. The usefulness of analyses of copper and iron for establishing the extent of general corrosion of low- and high pressure components, and subsequent transport of corrosion products to the steam generators, was discussed with members of the chemistry staf Although the licensee had a program to remove all copper-containing components from the secondary coolant system, the inspectors observed that only feedwater heater No. 5 in Unit I had been replaced so fa (Feedwater heater No. 6 in both units had originally been tubed with stainless steel tubes.) All of the remaining feedwater heaters had copper alloy tubes that are scheduled to be replaced with stainless steel
. tubes during the next two refueling outages for Unit 1 and the next three refueling outages for Unit 2 - a period of 3 to 5
~
years. Copper components remain a concerr. because the presence of copper in the sludge of steam generators has been shown to cause the type of tube denting that has been identified in both North Anna unit ,

the condensate polisher during earlier fuel cycles. Efforts had been continuing to reduce the levels of such ions as chloride, sulfate, sodium, potassium,. calcium, and magnesium by blowdown, especially during. normal shutdowns. However, the extent o which these potentially corrosive ions were being removed from crevices and.other localized environments was uncertain as long as large amounts of sludge were present in the' steam generato The cause of continuing wastage of carbon steel pipe in the low- ;
and.high pressure components of the secondary water system and
~
the buildu'p of sludge in the steam generators was considered by the inspectors to be of concern because sludge production in most other PWRs in Region II has been decreasing significantly-since licensees have implemented SGOG control guideline The inspectors reviewed in depth with representatives of 'the licensee the possible causes for sludge buildu These
' discussions focused on pH control and the use of boric acid to :
control denting of steam generator tubes. As discussed earlier, i the presence of copper feedwater tubes and the licensee's policy of maintaining a concentration of boric acid .in the steam generator water at 5 to 10 ppm had resulted in the pH of the !
steam generator being approximately 7.5 (at 25C). However, l even' though approximately 10. percent of the boric acid may 1 volatilize.'in steam and be transferred 'to the water in the hotwell, the pH of both condensate and feedwater had remained at 8.6.to This pH range was within the limits recommended by
,. the SG0G as a compromise to minimize corrosion of both copper and ferrous material The inspectors discussed with licensee personnel a perceived need to review the current chemistry. control program with the goal of reducing the transport of iron and copper oxide sludge into the steam generator, where, in the presence of known high concentrations of chloride, the denting phenomenon could be supported. The licensee's representatives agreed that better understanding of sludge formation was needed, but first priority had to be given to the control of existing denting conditions and prevention of extensive tube failur Water Chemistry Control Program The inspectors reviewed the current status of the following three elements of tne licensee's chemistry program:

The inspectors observed that the inline sampling system that was ;
being installed as part of the steam generator maintenance '
program with Westinghouse was not yet operable, although the monitoring panels had been installed. These panels were located in the turbine buildings of each unit and will provide continual readout for as many as five chemi stry parameters (sodium, hydrazine, pH, cation conductivity, and dissolved oxygen) from the following locations:
condensate makeup condensate pump discharge heater drains feedwater steam. generator blowdown main steam The inspectors consider that this system will provide sufficient data to permit the chemistry staff to continually monitor most chemistry control parameters. Chloride, sulfate, and silica will continue to be monitored through the use of grab samples, as will be the effluents of the condensate polisher During this part of the inspection no violations or deficiencies were identifie . Review of Licensee's Actions In Response to IEN Notices86-106 and 86-10 IEN 86-106 Feedwater Line Break The inspectors observed that, because of this licensee's particular concern over the pipe rupture at the Surry Nuclear Plant in December 1986 and the similarity of design of the Surry and North Anna Plants, a comprehensive program had been developed to address the concerns discussed in this Notice.

Immediately after the Surry accident' the power levels of the North- Anna ' units had been decreased to facilitate inservice inspection (ISI) test'ng of feedwater -lines. No indication o excessive thinning had been observe During the Unit I refueling outage 80 points on single phase fluid lines and 44 points on two phase lines were identified asL potential . sites of errosion/ corrosion thinnin As the ' result of the ISI inspection of the above 124 points, 101. additional points were . inspected (69 single phase and 32 two . phase)' and 27 pipe sections of feedwater lines,
'high pressure extraction steam' lines, and moisture separators heater'and crossover lines were replaced (some with higher allo _l material s) .

Candidates for a similar ISI program for Unit 2 were being identified for testing during the up-coming refueling outage for this uni 'The pre-existing ISI program for two phase systems was being reviewed for completenes A corporate level investigation of the role of materials in pipe- i thinning had been initiate ' The licensee was cooperating in an EPRI effort to develop a computer model for erosion / corrosion loss rate that will. include all of the elements that had been identified in the Notice as possible contributors to the Surry pipe rupture.

Also, an in-depth i review of this subject was being performed by designated groups within the Technical Support and Maintenance Department i 1
