  1. 1 CONNECTICUT YANKEE INFORMATION REQUESTED ON PWR FEEDWATER LINES DESIGN 1.

Provide as-built piping or isometric drawings of the feeduater line to steam generator sparger uithin containment. Shou details of the design such as dimensions, pipe schedule, sup-port type and locations, pipe restraints, and valve ls).

RESPONSE

The isometric drauings of the feeduater lines to steam generator no z e le inside containment are dsrived from the uxis ting ISI program. Both sets of isometrics provide design details including dimensions, supports, and locations, pipe restraints, and valves. The connecticut Yankee feeduater piping inside containment is 12" Schedule 80, seam-lace ASTH A-106, Grade B material. The steam generator feeduater nozzle configuration consists of (a) the nozzle to reducing elbou and (b) the reducing elbou to pipe veld joints. For details refer to enclosed Figure 671J561. 2348 184

i H2 CONNECTICUT YANKEE INFORMATION REQUESTED ON PWR FEEDWATER LINES DESIGN 2. Provide the results of any stress or fatigue analyscs uhich uas perfcrmed for this system.

RESPONSE

The original analysis of the feeduater piping system inside contain-ment uas done in accordance uith the precouve piping code ASA B31.1-1955. In addition, the stress analysis for the feeduater piping incide containment was extended to include seismic loads due to a ground acceleration of.17g. reanalysis of the feeduator piping system inside In June 19/5, a containment was donc considering secondary system fluid flou instabilities. The reanalysis included four (4) loading conditions: (a) deadueight, (b) normal thermal expansion plus end movements (steam generator nozzles and external containment structure), (c) scismic loade using a flat response spectrum (0.68g), and time history vater hammer event. The time history case, (d) a a loss of feed pumpe event, uas based on a forcing function chich uas postulated to be the oorst case and developed for use in the Hillstone Unit No. 3 analysis. The Millstone Unit No. 3 forcing function uas scaled doun by the ratio of the flou areas for subsequent application in the Connecticut Yankee feeduator sys tem analysis. The resulting forcing function was applied to the fecduater system utilizing time history methods to determine the generalized response of the feedvater piping. As a result of the rea na ly si s, it was concluded that the feeduater system piping inside containment required eight (8) additional snubbers and ten (10) rigid restraints. The additional snubbers and restraints as actl as complete spring hanger balance for the feeduater system inside containment ucre implemented during the 1975 outage. Based on the reanalysis and the resulting modifications instituted in 1975, it is concluded that the Connecticut Yankee fecduater piping system inside containment is qualified to existing ASME III Subsection RC critoria. A copy of the final stress summaries, stcan generator nozzle loads and associated isometrics from the 1975 reanalysis of the feeduater piping system is included. 2348 195

RESPOhSE The NDE performed during and after fabrication of the veld joints requested in Question 2 is summarised as follous. 1. After comple tion of the first tuo passes (Inert Gas Shielded Arc Welding Process), the inside condition of the veld joint uas inspected visually by a boroscope through the purging gas hole. 2. Subsequently, the Electric Metallic Arc Welding Process uas used to complete the veld joint. Each deposited velding bead uas thoroughly cleaned and visually examined for slag, remaining flux, cracks, lack of fusion, and blou holes. Corrective measures were instituted as required to ensure a sound veld icint. 3. All fie ld ucide in the feeduater piping system inside contain- ~ ment were 100% radiographed in accordance uith applicable code requirements. 4. The feeduater piping system was hydrostatically tested at 1.5 times the design pressure. 2348 226

The applicable power piping code ASA B31.1 (1955) did not impose any requirements for fracture toughness. 2348 228

H8 CONNECTICUT IANKEE INFORMATION REQUESTED ON PWR FEEDWATER LINES PRESERVICE/ INSERVICE INSPECTION AND OPERATING HISTORY 1. State uhether the feeduater systera velds received a preservice Vessel inspection in accordance with ASME Boiler & Pressure Code, Section XI.

RESPONSE

The feedoa ter sys tem, portions of which are ASME Section III, Class 2 (Equivalent), did not receive a preservice inspection per ASHE Section XI. Connecticut Yankee has been in commercial service since January 1, 1968 and NRC requirements to inspect Class 2 systems did not become effective until January 1, 1978 ohen changes to 10 CFR 50.55 invoked the Summer 1975 Addenda to Section.YI. 2348 229

Provide the extent of inservice inopection performed on the feeduater pipe to steam generator nozzle velds. Include the results of the examinations, any corrective actions taken, and causes of any failures.

RESPONSE

To date there have been no inservice inspections of the feedvater piping to steam generator nozzle velds. ISI program plans for Class 2 inspections require that one of these 14 " Category C-G ucids be volume trically examined during the service lifetime. 2348 230

  1. 10 CONNECTICUT YANKEE INFORMATION REQUESTED ON PWR FEEDVATER LINES PRESERVICE/ INSERVICE INSPECTION AND OPERATING HISTORY 3.

Provide the schedule and extent of inservice inspection for the feeduater system for the next inspection interval.

RESPONSE

The examination schedule for the current (second) inspection interval uhich runs from January 1, 1978 to January 1,

1988, requires that four (4) circumferential pipe velds be volumetrically examined, per Category C-G (Summer 1975 Addenda).

~~ In addition to the ASME XI requirements, Technical Spe'eification 4.12 on High Energy Piping Systems requires that six (6) tucive inch ( 12 ") pipe to cibou velds in the Class 2 portion of the feeduater sys tem be volumetrically and visually examined each forty (40) month inspection period for ten (10) years beginning in 1975. These inspections were completed in 1975 and 1979, with no reportable indications volume trically. Visual indications noted were removed by light grinding and found to be acceptable follouing reinspection. 2348 231

Mll CONNECTICUT YANKEE INFORMATION REQUESTED ON PWR FEEDWATER LINES PRESERVICE/ INSERVICE INSPECTION AND OPERATING HISTORY Provide any history of cater hammer or vibration in the feed-4. vater system and design changes and/or actions taken to prevent these occurrences.

RESPONSE

Several incidents believed to be attributable to vater hammer transients in the feeduater system have occurred at the subject unit. In addition, vibration of the feeduater Lines inside containment has been observed during normal operation. An inspection of the feeduater piping and supports inside containment in May 1975 revealed a failed friction damper and a broken pipe clamp on a spring hanger. As a result of the observed feeduater line vibra-tion and the subsequent findings, Stone a Webster reanalysed the feeduater piping system in June 1975 as detailed in Response #2 regarding the design of the feeduater piping system. The corrective measures instituted vere: (1) addition of snubbers and rigid restraints; and (2) a complete spring hanger rebalance of the feedvater piping system inside containment consistent uith the results of the reanalysis. The corrective measures vere imple-men ted during the 1975 refueling outage. To date no excessive vibration levels have been observed in the feeduater piping system during normal operation. Additional information is provided in the D. C. Suitser letter to A. Schuencer, dated July 15, 1975. 2348 232

v H12 CONNECTICUT YANKEE INFORMATION REQUESTED ON PWR FEEDWATER LINES PRESERVICE/ INSERVICE INSPECTION AND OPERATING HISTORY 5. Provide a description of feeduater chemistry controls and a summary of chemis try data.

RESPONSE

Feeduator chemistry controls for Connecticut Yankee are summarized in Table 3. When the normal value is exceeded, the cause of the problem is investigated and corrected. Plant responses to exaceding normal chemistry escalate, depend on the parameter and the nature a of the problem. Control values uhere in chemistry co_ndi_tions that lead to various actions including pouer reduction and shutd'an are listed in Table 3. Some chemistry parameters are monitored continuously by means of on-line ana lysis, as indicated in Table 3. The other listed para-me ters are determined on a sampling basis. Feeduater chemistry is also controlled indirectly by means of s team generator chemis try control. Thus, uith some parameters, a fault feeduater condition vould be detected in the steam genera-tor prior to becoming detectable in the feeduater, due to the con-centrating action that occurs in steam generators. On-line wnlyzers and chemistry controle implemented for steam generator chemistry are provided in Table 3. Typical chemistry data for Connecticut Yankee is given in Table 4. 2348 233
