Subject:

Response to NRC Bulletin 87-01:

Thinning of Pipe Walls in Nuclear Power Plants Gentlemen:

On July 9, 1987, the NRC issued Bulletin 87-01, " Thinning of Pipe Walls in Nuclear Power Plants". The purpose of this bulletin was to request licensees to submit information concerning their programs for monitoring the thickness of pipe wall in high-energy single-phase and two-phase carbon steel piping systems.

In 1982, Toledo Edison developed a program to inspect areas for thinning of pipe wall (erosion / corrosion).

Since then our program has continuously been updated to take into account various industry experience and regulatory information.

Attachment A provides Toledo Edison's response to the request for

(

information. Attachment B provides Erosion / Corrosion Inspector Summary results at Davis-Besse Nuclear Power Station, Unit No. 1.

l Question 2.

Describe the scope and extent of your programs for ensuring that pipe vall thicknesses are not reduced below the minimum allovable thickness.

Include in the description the criteria that you have established for:

a.

Selecting points at which to make thickness measurements b.

Determining how frequently to make thickness measurements c.

Selecting the methods used to make thickness measurements d.

Haking replacement / repair decisions Response 2.

In November of 1982, Davis-Besse initially selected areas to be inspected. The criteria used to select these areas was based upon a history of pinhole leaks attributed to l

l erosion / corrosion and the issuance of INP0's Significant

)

l Operating Experience Report (50ER) No. 82-ll," Erosion of I

Steam Piping and Resulting Failure".

From these areas a list of piping and fittings in the extraction steam system, various sections of piping in the moisture separator / reheater (MSR) drain lines, and the feedvater heater drain lines were considered to be prime candidates for vall thinning due to erosion / corrosion. Subsequent to the inspections of 1983 and 1984, an evaluation was

i l

Docks N 50-346-Licenna No. NPF-31 Sarial'No.e1-749 q.

i performed.on. cascade drain flow to the deaerating' heater I

and flow from the feedvater heaters to the condenser.-In 1986, an evaluation vas performed on the. extraction and I

~

exhaust steam piping for areas of potential erosion / corrosion.

~!

Response 2a...The above criteria has been used for selection of inspection areas until June,-1987. The inspection program ~-

is being' revised to incorporate the guidance of.this bulletin and recent industry experience, (e.g., Surry Event).

Response 2b. The initial inspection in January of 1983 found the vall i-thickness to be above that of the code required minimum vall thickness. Therefore, the inspection' frequency was changed from initially selected frequency of semi-annual and annual (two separate inspection frequencies were l

selected) to coincide with each refueling outage-inspection.

Response 2c.

The ultrasonic non-destructive examination method has been selected for the use in the establishment of vall thickness. This has been evaluated as the most technically.

L appropriate and provides ease of inspection interpretation, in-house expertise, and available inspection services, when needed.

l

Docket No. 50-346 License No. NPF-3 Serial No. 1-749 Response 2d. Replacement and repair decisions are predicated upon the severity of the thinning or leaking found in the piping or components. In cases where analysis has demonstrated it is safe to continue operation, operation has continued until l

I such time as the repair or replacement was accomplished.

These decisions are based on the safe operation of the i

plant and personrel safety.

The initial inspections of January 1983 vere based on selected system areas with fluid-bulk velocities and two-phase flow conditions. Currently, computer programs (Drain 13 and CHEC) are being used to augment the analysis l-and to select points at which to make thickness measurements. The analysis used to establish the criteria j

Question 4;-

Chronologically list and' summarize the results of all l inspections that have been performed, which were a.

specifically conducted for the purpose of identifying pipe vall thinning, whetheror not pipe vall thinning was'

-1 discovered even'.though that was not the purpose.of that inspection.

Response 4.

The original program to measure the vall thickness of' piping and fittings subjected to erosion / corrosion was '

developed in~ November of 1982. (see response.to question.2) 1982 Inspection Prior to ti;e establishment of the inspection program in November 1982, areas.such as HSR drains and the MSR tank drains had shown' evidence of leaking due to two-phase flow.

Subsequent inspections' revealing continued degradation has resulted in a redesign of these' drain lines. Replacement is currently scheduled for the 1988 refueling outage.

1983 Inspection During the January, 1983 outage, two elbows in the extraction steam piping system were inspected by the ultrasonic examination metho!..

The results of this inspection showed some vall thinning had occurred; however, the readings were above code allovable minimum vall

Lictnsa No. NPF-3 j

S rial No. 1-749 thickness with the exception of one small area which was evaluated as pitting corrosion. This area was evaluated and found acceptable for continued operation.

1.

Subsequently, during the November, 1983 refueling outage, additional inspections were performed on selected areas.

The inspected areas included extraction and exhaust steam lines, MSR to feedvater lines, MSR drains, and the reheat startup drain lines. The results of this inspection revealed one area'of thinning in the HSR drains that was below the code allowed minimum vall thickness. Piping on the HSR drains was replaced.

1984 Inspection The 1984 inspection included portions of the same systems as the 1983 inspection with the addition of three vent lines from the feedvater heaters to the deaerating heaters.

The inspection revealed three areas of vall thinning in the HSR drain tank control valve piping to the condenser that were below the code allowed minimum vall; however, evaluations for these three items could not be documented.

Subsequent calculations indicated that these three areas are acceptable for operation until the 1988 refueling outage.

Dockst No.'50-346 iLic:nsa No. NPF-3 S2 rial No. 1-749-1985 Inspection The areas inspected in January and October 1985 were reduced to the HSR drain lines to the feedvater heaters.

Four areas indicated evidence of vall thinning; however, all vere above the code allowable minimum vall thickness.

I 1987 Inspection l

The HSR drain tank piping, the HSR header pipe to the I

condenser and fittings in the No. 1 main feedvater booster pump discharge line were inspected in 1987. Ultrasonic l

examination of piping and fittings in the HSR drain line and the HSR header identified conditions of vall thinning below the code minimum allowable. This piping was repaired to allow continued operation. Inspected areas in the HSR drainline, with the exception of one section of piping, could not be confirmed as meeting the code minimum j

1 allovable thickness. The analysis performed indicated that in the vorst case of thinning the remaining vall thickness exceeded that required by the system design conditions for operation. Based on the evaluation the system vill remain i

operational until the next refueling outage at which time

{

l the piping is scheduled for replacement.

' Docket.Ns. 50-346 Lic0ns3 No. NPF-3 Snriel No. 1-749 An area of the HSR drain header approximately one inch in diameter was found to be below the code minimum allowable vall thickness. Analysis of the remaining vall thickness of this area indicated that it exceeded the vall thickness required to meet design conditions for operation. The HSR drain header is included in HSR drain system replacement which is scheduled for the 1988 refueling outage.

D:ckat No. 50-346 Lic:nsa No. NPF-3 Strial No. 1-749 QUESTION 4b.

Describe what piping was examined and how (e.g., describe the inspection instrument (s), test method, reference thickness, locations examined, means for locating measurement point (s) in subsequent inspections).

Response 4b.

The piping and fittings inspected to date have been within the extraction steam, MSP drains, MSR tank drains, and main feed pump discharge lines. The inspection method used has been ultrasonic examination, utilizing either a Krautkramer model DH2LCD ultrasonic thickness gauge, or Krautkramer models USIP-11, USM2, or USM6 pulse-echo type ultrasonic flav detection instrument.

Calibration blocks of similar materials and thicknesses are utilized conforming to the manufacturers recommendations.

Examination locations are specified on sketches or marked up on drawings which are attached to Maintenance Work Orders (MV0) and maintained as part of the MVO package.

' Question 4d.

Describe actions already taken or planned for piping that has been found to have a nonconforming vall thickness.

If you have performed a failure analysis, include the results of that analysis. Indicate whether the actions involve repair or replacement, including any change of materials.

Response 4d.

Dispositions of nonconforming vall thickness have included 1

the use of Furmanite, repairs by velding, piping and I

fittiag replacement with like materials, and redesign and replacement with more erosion / corrosion resistant materials.

Analysis have been performed on all nonconforming vall thickness inspection resulta. The tc olts of the analysis are 1) accept as is and reinspect at the next scheduled inspection, 2) repair or replace, or

3) redesign and replace. The analysis of the MSR drain piping indicated that relocation of system valves and the replacement of the carbon steel piping and fittings with stainless steel down stream of the valves vould reduce two-phase flow, thereby reducing erosion / corrosion. The modification and replacement of the MSR piping is scheduled for the 1988 refueling outage.

Question 5.

Describe any plans either for revising the present or for l

1 developing new or additional programs for monitoring pipe j

i vall thickness.

j Response 5.

The current erosion / corrosion program at Davis-Besse is under review to include recent industry experience and this Bulletin. Changes under consideration include the following:

1.

Improve the selection of inspection areas through the use of improved selection criteria incorporated in available computer programs, 2.

Expand the number and extent of systems to be evaluated, 3.

Refine the inspection grid and bench marks to assure consistent repeatability of results, 4.

Refine the data retention and historical records to assist in prediction of system piping or component replacement.

The evaluation and potential implementation of the above into our erosion / corrosion program is scheduled for the pipe vall thickness inspections which will be performed during the 1988 refueling outage.
