Dear Mr. Denton:
n The purpose of this transmittal is to provide a technical basis for og elimination of postulated pipe ruptures in high energy piping, the associated w o n. dynamic effects, and the required hardware to mitigate these dynamic effects.
$@ Our program takes advantage of state of the art leak before break (LBB) jg technology and advanced engineering methods in pipe stress analysis to provide appropriate pipe break protection.
(D x N! This program is consistent with the NRC Staff Piping Review Committee's Q
g recommendations in NUREG 1061, Volume 3, and those programs which formed the bases for schedular exemptions authorized for numerous plants for reactor oct coolant system main loop piping (References 1 through 4 have been provided by jh HL&P). Ill4P considers the application of the leak before break technology to be a more effective and reasonable approach to ensure adequate pipe break protection than the installation of pipe restraints nd jet shields.

Repo Onf
3 ST-HL-AE-1681 h n @ng & h Cmpany Fila No.: G9.10 Page 2 This program will be applied to STP Unit 2 only.
HL&P intends to use the leak-before-break technology on the 16 lines listed in Table 1 of Attachment A to this letter. All of these break locations are located inside the containment building.
The enclosed technical bases, Attachments A through F, are provided in support of our program for eliminating from consideration postulated circumferential and longitudinal pipe breaks and their associated dynamic effects. Elimination of these postulated breaks would have the following effects on STP designs o Eliminate the need to install associated pipe break restraints and jet impingement shields, o Eliminate the need to consider associated dynamic effects and loading conditions including jet impingement loads, subcompartment pressurization, blowdown loads in the lines, attached piping and adjacent components, and component supports.
This program will not affect the followings o Emergency Core Cooling System (ECCS) design bases o Containment design bases o Equipment qualification design bases o Engineered Safety Features System response o Design margin of RCS heavy component supports The alternative pipe break criteria presented in Attachment A through F are provided as specific acceptance criteria for auxiliary and balance of plant piping r>ystems for STP Unit 2. These attachments address the NRC questions raised relative to Reference 5 (Beaver Valley, Unit 2) as they may relate to the South Texas Project program. These criteria provide the technical bases for an exemption under 10CFR50.12(a). Accordingly, HL&P hereby applies for an exemption under 10CFR50.12(a) for the treatment of pipe breaks on the piping listed in Attachment A for STP Unit 2 given that they meet all acceptance criteria relative to leak-before-break analysis. Special circumstances exist in that the state-of-the art in fracture mechanics now provides analytical means to achieve the underlying purpose of GDC-4 without requirements to install pipe whip restraints or jet impingement shields.
L1/NRC/ab
7 ST-HL-AE-1681 Houston Ughtiag & hmer Company Fils No.: G9.10 Page 3 This exemption would eliminate the need to install the associated pipe whip restraints and jet impingement shields and to eliminate the need to design for the dynamic effects associated with thess breaks. These dynamic effects are specifically defined as the effects of missiles, pipe whipping, subcompartment pressurization, and fluid jets. Approval of this request would (1) eliminate the need to postulate longitudinal and circumferential pipe breaks in the listed piping in Attachment A, and (2) eliminate the requirement to analyze and design for the following dynamic effects of these breaks: jet impingement, blowdown loads, pipe whip, reactor cavity pressurization, subcompartment pressurization transients, and load combination assumptions.
. This exemption request does not affect the containment pressure boundary, the emergency core cooling system, or environmental qualification design bases.
Pursuant to 10CFR50.12(a), HL&P believes the requested exemption "will not endanger life or property or the common defense and security and is otherwise in the public interest."
A schedule to provide information to the NRC of significant analysis completion dates is included as part of Attachment A. We look forward to meeting with NRR staff to discuss this program further.

7 Attachment A ST-HL-AE- 1681 PFN: G9.10 Page 1 of 5 TECHNICAL DESCRIPTION FOR APPLICATION OF LEAK BEFORE BREAK TO HIGH ENERGY AUXILIARY SYSTEM PIPING FOR SOUTH TEXAS PROJECT A. INTRODUCTION The purpose of this effort is to provide a technical basis for elimi-nation of postulated pipe ruptures, the associated dynamic effects, and the required hardware for the mitigation of these dynamic effects. This will be accomplished through application of the state of the art leak-before-break (LBB) technology by using a screening process developed to minimize the total effort. Latest technology developed in piping stress analysis may also be used as required to evaluate piping loads that are the basis of the fracture mechanics analysis.
B. METHODOLOGY The program involves the application of fracture mechanics technology, leak-before-break concept, a three stage screening criteria, and the reassessment of conservatism based on current ASME Codes and other technological developments. These technologies will be applied to high energy piping systems identified in Table 1. The implementation of this~
methodology to enhance the success of the program is dependent on a close interface relationship between all the parties involved for their respon-sibilities as defined in Attachment B. A brief description of each of the three key technical segments are described in the following sections.
The planned schedule for implementation of the program is provided in Table 2.
B.1 SCREENING CRITERIA Objective The objective of developing the screening criteria is to minimize the implementation effort and to avoid any unnecessary conservatism in the application of LBB approach. The screening criteria, based on general industrial and specific Westinghouse technology (Attachment C), provides the basis for a request to the NRC for approval of the LBB initiative.
Application of these criteria will allow the elimination of the breaks, the associated dynamic effects and the elimination of the need for whip restraints and jet shields; when required, subsequent detailed analysis will demonstrate LBB for those lines selected.
Screening Criteria Parameters The screening process for selecting cases for detailed fracture mechanics evaluation is based on the review and evaluation for pipe failure mecha-nisms, leak detection capability, crack stability and fatigue crack growth. The key areas of screening are highlighted below:
txt\abp
m Attachment A ST-HL-AE-1681 PFN: G9.10 Page 2 of 5 Review of Potential Pipe Failure Mechanisms
- Fatigue
- Water Hammer
- Corrosion Leakage Detection Visual outside containment (only one location to require review)
Reg. Guide 1.45 systems inside containment Augmented in-service inspection inside containment, if required Crack Stability
- Material strength and toughness Limit moment approach
- Maximum longitudinal stress approach Fatigue Crack Growth Transient descriptions
- Transient loadings (including flow stratification review)
From an analytical point of view, the screening criteria is dependent on the limit moment approach and the maximum longitudinal stress approach to be incorporated into a criteria document. These approaches, applied in sequence, will limit the cases requiring detailed investigation and assure the successful implementation of using the available industrial and Westinghouse specific technology to minimize the effort with no sacrifice of safety. ,
B.2 FRACTURE MECHANICS ANALYSIS The implementation of screening criteria will provide information on the material strength and the severity of mechanical and thermal loadings.
The application of fracture mechanics technology to implement the LBB concept can be categorized into three separate levels based on the required effort of implementation as described below.
- 1. Hand Calculations Without Finite Element Analysis This method applies to those cases where the combination of material strengths and all applicable loadings for a specific pipe size group meet the most conservative screening criteria requirements. 1he l application of hand calculation with simple formula minimizes the required effort for an expeditious completion of these cases.
txt\abp >
m Attachment A ST-HL-AE- 1681 PFN: G9.10 Page 3 of 5
- 2. Partial Finite Element Analysis This method applies to those cases where the combination of material strengths and all applicable loadings for a specific pipe size group meet the medium level requirements of the screen criteria. For these cases, available analytical results will be used and finite element analysis will be performed only on an as needed basis. The deterni-nation of where this method is to be applied is dependent on the results of the screening process and previous knowledge of the LBB application to the auxiliary system piping. The adoption of limited finite element analysis, where applicable, will reduce the effort and time significantly for this program.
- 3. Detailed Fracture Mechanics Analysis Using Finite Element Analysis Methods This method applies to cases where the combination of material strengths and all applicable loadings for a specific pipe size group meets the lowest level of the screening criteria. For these cases, finite element analysis must be applied to both the crack stability analysis and leakage calculations to demonstrate the applicability of LBB.
- 4. Material Testing Material properties are being reviewed for the actual plant piping.
To date the following testing is planned. Based upon the complete material data review, additional testing may be added to the programs as determined to be required.
a) 30" Main Steam Line (SA 155 KCF70 Class 1)
The following tests will be completed for both base metal and weld metal samples.
- Obtain 3 J-R curves at 550 F
- Obtain 3 stress-strain curves at 550 F
- Obtain I stress-strain curve at RT l b) 8" SI line (SA-312 TP 304L)
The following test will be completed on base metal.
- Obtain 3 J-R curves at 550 F
- Obtain 3 stress-stain curves at 550 F
- Obtain 1 stress-strain curve at RT txt\abp L-
Attachment A ST-HL-AE- 1681 PFN: G9.10 Page 4 of 5 B.3 METHODS TO REASSESS CONSERVATISM The purpose of this LBB application program is to eliminate postulated pipe breaks and with them the hardware that would be needed to mitigate dynamic effects of the postulated pipe ruptures. If necessary, reassess-ment in conservatisms associated with conventional stress analysis will help the elimination of these breaks by either enhancing the probability of success for fracture mechanics analysis or qualifying more locations for elimination as arbitrary intermediate breaks. Only proven methodolo-gy will be used in this process. The technology to be applied is either recommended by the NRC piping review committee, summarized in NUREG-1061 reports, or existing in previous licensing precedents or technical reports endorsed by the U.S. NRC.
C BASE SCOPE The scope for the schedular exemption to eliminate postulated pipe ruptures, the associated dynamic effects and the required hardware for the mitigation of these dynamic effects is summarized in Table 1.
