Dear Mr. Carey:
B. Grimes
Subject:
Interim Review Results of WHIPJET b ][. ,
By letters dated September 6 and October 10, 1985 Duquesne Light Company ~
formally submitted information regarding the WHIPJET program (application of leak-before-break criteria to balance-of-plant piping). By letter dated March 3, ,
1986 we provided our preliminary assessment and position on this issue. In addition, we have had five progress report meetings, one special meeting on '
- August 13, 1986, and numerous conference calls to obtain additional information. ,, i In the August 13 meeting your staff requested that we comunicate an interim r review status to you, describing issues that are resolved, issues that have ;
major problems.and issues that have minor problems. In that meeting we terminated the discussion of the issucnce of an exemption or CP amendment-since these legal documents are all predicated upon the availability of a -
favorable safety evaluation which we have not yet been able to prepare at this time. However, we believe that the description of the present status in
, Enclosures 1 and 2 should be useful to you. Our concerns in these enclosures i have been either formally sent to DLC or informally discussed with DLC representa-tives.
i We believe the remaining two major problem areas are the lack of material test t- data and the detectable leak rate for ferritic piping.
4 Based on the preliminary information submitted, to date, for austenitic pipe lines and our assessment of fracture mechanics and leak rate analyses, it <
appears that only lines 6 inches and greater in diameter will satisfy the current margins for leak before break in NUREG-1061, Vol. 3. However, the i final stability and fatigue analyses and results have not been submitted by DLC. Until the information in Enclosures 1 and 2 and the stability and fatigue analyses are submitted for our review, we will not be able to reach a final conclusion and provide a completed safety evaluation.

,. Enclosure 1 POSITIONS AND REQUESTED INFORMATION
- 1.
Subject:
Representativeness of plant materials to test materials Position: a. DLC will verify that the materials in the plant are conservativelyrepresentedbythetestmateriais,
- b. DLC will catalog the materials asailable for fabrication into test specimens (ferritic pipe and weld rod). DLC will choose the three heats (pipe and weldment) based on upper and lower bound values of yield and average yield strength. If there is not enough material in'a given heat with limiting yield strength (e.g. upper bound value) the matrix of three tests of each heat may be altered in order to use the bounding material, provided -
~
the total number of tests is unchanged.
- c. DLC will have all the material certifications available for staff review.
- d. For the non-nuclear piping in the WHIPJET Program NRC will require that bounding toughness and tensile properties be used in the fracture mechanics analyses to ensure that the evaluation is conservative.

. DLC will discuss the weld fabrication procedures used to fabricate test specimens relative to the procedures used throughout the plant.' This discussion should justify that the toughness values of the pipe welds in the WHIPJET Program are not non-conservative relative to the tough-ness values indicated from the test program.
DLC will propose a method of categorizing material properties for the non-nuclear piping in the WHIPJET Program.

Fatigue crack growth analysis [
~
Position: a. DLC will perform as realistic an analysis as possible using service level A and B loads. The aspect ratio for the crack in the fatigue evaluation should be 6. The aspect ratio will remain constant throughout the analysis.
Unless otherwise justified the maximum allowable flaw depth is the smaller of
- 1) 60% of the wall thickness, or
- 2) the depth at which the plastic zone is equal to the remaining ligament.
- b. The length of the fatigue crack must be less than both:
- 1) the length of the instability thru-wall at 2 (N+5SE)
- 2) 1/2 (instability thru-wall flaw at (N+SSE)).

Enclosure 2 BEAVER VALLEY, UNIT 2 WHIPJET PROGRAM INFORMATION RELATIVE TO PWR-A ENGINEERING BRANCH AUDIT I. GENERAL
- 1. DLC states in Section 5.1.2 of their May 14, 1986, WHIPJET Draft Report that the linear (aT )y and nonlinear (AT )2 components of the through wall temperature distributions during thermal transients were conservatively approximated by 80% and 50% of the fluid temperature change (AT). DLC will be required to demonstrate that e these approximations are conservative since AT yand AT are 2
functions of the fluid velocity, material thermal properties, fluid
, temperature change, rate of change of fluid temperature and pipe ;
outside diameter conditions. -
Status: Information submitted in the August 11, 1986, report is under review by the NRC staff.
- 2. DLC indicates in Section 5.5.1.3 of their May 14, 1986 WHIPJET Draft Report that only 10% of the effects of the nonlinear component of the through wall temperature distribution during thermal transients will be included in their WHIPJET total inside wall stress calculation. DLC will be required to justify this percentage in greater detail than that which is discussed in Section 5.5.1.3.
l Status: Information submitted in the August 11, 1986, report is l under review by the NRC staff.
l
- 3. DLC will be required to identify typical piping components in the WHIPJET Program, e.g., valves, elbows, tees, reducers, etc. whose wall thicknesses are greater than the thicknesses of the connected piping. These increased thicknesses could affect the distribution of internal forces in piping systems and cause higher thermal l
transient stresses in the connecting welds than in the connected piping.

II. WATER HAM.MER
- 1. In Section 4.2.2 of the May 14, 1986 Draft Proaress Report, DLC stated that: 1) in general the approach taken to address AVPS '
water hammer concerns was to prevent or minimize water hammer effects through system design features and eperating procedures, and ?) to assure that water hammer events initiated in the secondary systers do not compromise the performance of the Westinchouse supplied safety-related systems and components, the results c' Westinghouse water hanmer investigation have been reflected in
, desian interface requirements for the balance of plant (80P1 design. .
l
DLC will be required to provide information to verify that the system design features and operating procedures are adequate to address water hammer concerns. In particular, DLC will be recuired: 1) to identify documentation, including systerIdesign descriptions (SDDs), Piping and Instrumentation Diagrams (PAIDsi, operating procedures and Westinghouse-BOP interface recuirements for the pipino' systems in the BVPS-2 WPIPJET Program, which would substantiate that the DLC approach to address water hammer concerns has been properly implemented and ?) be prepared to make.available

Status: A response by DLC on this issue will be required.
- 3. DLC was previously requested to modify its list of fluid transfer.ts to provide additional details of its assessments of these trarsients.
Where transients were characterized as applicable, DLC was requested to identify the operating procedures which addressed the water hammer concerns and the analyses in which the transient related loads had been quantified and included in the piping stress analyses. DLC should be prepared to have the modified list of transients for revier during the audit.
It appears that only normal operating conditions have been addressed
~
in the list. Other operating c'onditions (e.g., emergency and faulted) as well as testing conditions should be addressed to assess inadvertent water hammer occurrences during these conditions.

III. STAFF EVALUATION OF CHEMICAL / VOLUME AND CONTROL PIPING SYSTEM STRESS .'
~
ANALYSIS
- As a part of this audit, the staff through its consultant, ETEC, will conduct a detailed evaluation of the Chemical / Volume and Control (CHS) piping system stress analysis. The items listed below are indicative of the type of information that will be required to enable the staff to complete this evaluation. If, as a result of this review, the staff identifies any unacceptable safety-related findings, the staff will request information relative to these findings as they apply to other WHIPJET Program systems to determine the possible generic consequences.
- 1. Since the analysis of record for the ASME Class 2 & 3 and ANSI /ASME B31.1 portions of the CHS piping system is based on stress intensification factors and the DLC WHIPJET piping analyses are to be based on ASME Code Section III, Class 1 stress indices, DLC will be required to demonstrate how its analysis of record for the CHS was modified for the WHIPJET analyses.
- The information need in Part III of this enclosurc may be modified as a result of discussions to be held during September.
