SUMMARY
Background
This report provides the status of the review of high and moderate energy line breaks (HELB/MELB) performed under the Independent Design Review (IDR) for the Byron Generating Station, Units 1 and 2, of Commonwealth Edison Company. It supplements the previous report dated May 1984 by extending it in the review area of HELB/MELB design. Other review areas are not covered in this report.
Under the IDR, Bechtel Power Corporation has been reviewing the Sargent and Lundy Engineers (Sal) design of three selected safety systems for adherence to design -requirements, for technical adequacy, for adequacy of the design process, and to draw broader conclusions as appropriate. The systems selected for-review are the component cooling water (CCW) system, the essential service water (ESW) system and the 125 Volt (V) de distribution system.
The review effort reported within included two aspects of the Byron design for HELB/MELB:
- 1) The adequacy of the protection provided the CCW, ESW, and 125 V de systems against the effects of HELB both inside containment and in the auxiliary building;
- 2) The adequacy of the protection provided from the effects of MELB involving the reviewed systems both inside containment and in the auxiliary building.
iii (11900)
i Plans and Activities The methodology chosen for review of HELB/MELB effects included an initial review of the selected systems for the adequacy of their protection from pipe whip effects inside containment. The results of this initial pipe whip prot:ction review were reported in Appendices A-2 and B-2 of the May 1984 Interim Report. The balance of the program includes completion of the HELB review (pipe whip and jet effects) and the ELB review (spray / flooding) both inside containment and in the auxiliary building.
R;sul ts HELB (Inside Containment)
The HELB review for pipe whip and jet (inpingement) effects on the reviewed systems is essentially complete. The review consisted of evaluating whether the CCW or ESW systems represented potential targets from either pipe whip or jet associated with the FSAR Appendix 3.6 identified HELB locations. No deficiencies in pipe whip protection were noted. In the course of the review, 11 instances of potential direct jet impingement were identified. Of these,
, 10 involve the CCW system and 1 involves the ESW system. All 11 cases were included in a single potential observation which was subsequently forwarded as an Observation Report to S&L for response. This Observation has been responded to by S&L for 10 out of the 11 cases, and the design was found accIptable for all 10 cases. The Observation is still under review for the remaining case, pending receipt of additional infonnation from S&L. Desi gn process adequacy is also still under review.
iv (1190o)
This Observation is tentatively not regarded as safety significant, subject to receipt of information from S&L on the one remaining case.
HELB ( Auxiliary Building)
Th2 postulated HELB break points identified on a specially-designated set of piping layout drawings provided by S&L have been reviewed. For the postulated breaks reviewed, no deficiencies were noted.
MELB (Inside Containment)
The MELB review has identified no adverse condition for the selected safety systems. The review of MELB effects inside containment is continuing.
MELB ( Auxiliary Building)
The MELB review has identified no adverse condition for the selected safety systems. The review of MELB effects in the auxiliary building is continuing.
Csnclusions Until-the review is complete, only limited conclusions can be drawn. The rsview effort covered by this report tends to confirm the adequacy of the design for protection of the Byron Station against HELB/MELB effects for the rsviewed systems, both inside containment and in the auxiliary building. A possible exception is one situation involving jet impingement. Pending receipt of additional information on this case, it does not as yet appear to have safety significance.

I Section 1 INTRODUCTION ,
1 1.1 PURPOSE Commonwealth Edison Company (CECO) has requested Bechtel Power Corporation (BPC) to conduct an independent design review (IDR) of the Byron Station, Units 1 and 2. Review of HELB/MELB considerations in the design of the selected systems was specifically included in Bechtel's IDR scope. The initial portion of this review effort, as completed through May 31, 1984, was described in the Interim Report dated May 1984. This Interim Report describes the additional work perfomed (through June 21,1984) beyond that covered in the May 1984 report. The conclusions reached reflect the results of all HELB/MELB review work perfomed to date. Further work remains to complete this effort. This work will be described in the Final Report.
The review work described herein was perfomed in accordance with the Program Plan, dated May 1984, including the approved Quality Assurance program. It is intended to help fulfill the stated purpose of that Plan, i.e., to provide an additional level of confidence in the design by Sargent and Lundy Engineers (S&L) of the Byron Station.
1 (11900)
1.2 SCOPE This IDR scope required a review of the following three systems:
component cooling water (CCW), essential service water (ESW) and Class 1E 125 Y dc distribution. The system boundaries are as generally described in the FSAR. The review includes consideration of instrumentation and electrical components when considered functionally essential. The HELB/ELB review covers that design work done by S&L as supported by certain Westinghouse analyses. The scope of the HELB/MELB review included (also see Table 1):
A review of the FSAR-identified HELB locations inside containment for potential HELB effects (pipe whip impact or direct jet impingement) on the CCW and ESW systems -- no portion of the Class 1E 125 V de distribution system is inside containment; A similar review of the three reviewed systems in the auxiliary building for the HELB locations identified by S&L on special piping layout drawings;
- A review both inside containment and in the auxiliary building of potential ELB effects (spray / flooding) from oth r systems on the reviewed systems; and A review inside containment and in the auxiliary building of potential ELB effects on other essential systems from the CCW and ESW systems.
II) The review outside containment was limited to the auxiliary building as this is the only portion of the plant external to the containment where high energy lines and the selected safety systems occur in the near vicinity of each other. ELB effects were reviewed in the same building.

This scope of work addressed the following functional areas:
- Identification / implementation of commitments and criteria; Design adequacy; Adequacy of the S&L design process, including evaluations of engineering judgements and assumptions, use of standard design methods and the adequacy of the documentation of design calculations; and Review of S&L's interface with Westinghouse.
Specifically excluded from the scope of this review are the following HELB/MELB considerations:
Review of stress calculations and specific selection criteria that established break locations and type of break (S&L stress analysis is separately evaluated);
Review of pressure / temperature calculations establishing post-break design conditions since CCW and ESW systems are not high energy systems; and Review of design adequacy of structural elements (e.g., walls) for potential whip, jet, or pressure effects since CCW and ESW systems are not high energy systems.
Construction verification is not included in the scope of the IDR.
The IDR essentially covered S&L design work completed through April 1,1984, but some S&L work in progress after this date was considered and is identified where used.

1.3 DESCRIPTION
OF THE REVIEW AND STATUS The HELB/ELB portion of the IDR was structured to review design requirements, design adequacy and the design process, and then to make an overall assessment based on the review of the three selected safety systems. Major emphasis has been placed on the adequacy of the design of the final product. Consideration will be given to the implications of a discrepancy in one area upon the adequacy of the design in other area s. The initial review of pipe whip effects inside containment was described in the Interim Report dated May 1984. The review process for this subsequent report has been more extensive, completing the pipe whip review as well as covering jet impingement inside containment and assessing the impact of both of these pipe break dynamic effects in the auxiliary building.
The IDR team perfonned its own analytical review to evaluate the design adequacy. The methodology of the IDR review was consistent with the Byron FSAR cornitments. Break locations were determinad from S&L documentation and then each break selected for review (based on estimated risk of adverse effects) was evaluated as to whether the selected review systems represented " targets" for the reviewed break, either as a consequence of pipe whip or as a consequence of the associated jet. Generally accepted evaluation principles were then applied and discrepancies noted. Existing barriers and restraints were
. considered.

Section 2 OBSERVATIONS AND RESOLUTIONS
^
2.1 OBSERVATION REPORTS The IDR team has issued one Observation Report (OR) for items covered by this report. The OR is summarized below, its significance noted, and a status of resolution described. The OR has been numbered to correspond to the project file system, which begins numbering when a potential Observation is issued.
2.2 . COMPONENT COOLING WATER (CCW) SYSTEM Observation Report 8.24 _
Observation: -
FSAR Section 3.6.1.3 commits to the protection of certain essential z systems following any postulated pipe rupture so as to maintain system functionality. Table 3.6-3 identifies the CCW system as one of these essential systems. The Observation Report identified 10 situations where high energy line breaks may result in direct jet impingement on CCW piping inside. containment. S&L was requested to provide justification of commitment compliance and design adequacy for the identified conditions.
l
^
l o
9 (11900)
The Observation is tentatively not considered safety significant based on the likelihood that further analysis may show that the impinged lines would not fail or, if they did, their failure will not affect CCW system functionality.
Resolution:
S&L has partially responded, addressing 9 of the 10 situations identified as involving direct jet impingement on CCW lines. The response clarified the FSAR intent that only certain portions of the CCW system may be required to remain functional depending on the response required for each potential break.
S&L evaluated the resultant sequence of events after each postulated break addressed, and concluded that the affected portion of the CCW system is not essential for the break postulated.
Based on the additional information provided by S&L, the IDR team has evaluated each of the 9 situations and has accepted the basic S&L conclusions that the existing design is adequate for the situations addressed.
This Observation is still under review for the remaining CCW system situation, pending receipt of additional infomation from S&L and evaluation of the design process.
10 (1190o)
2.3 ESSENTIAL SERVICE WATER (ESW) SYSTEM Ob:ervation Report 8.24 Observation:
FSAR Section 3.6.1.3 commits to the protection of certain essential systems following any postulated pipe rupture so as to maintain system func tionality. Table 3.6-3 identifies the ESW system as one of these essential systems. The Observation Report identified one situation of potential direct jet impingement on ESW piping inside containment from a postulated feedwater line break. S&L was requested to provide justification of commitment compliance and design adequacy for the identified condition.
The Observation is tentatively not regarded as safety significant based on the likelihood that further analysis may show that the impinged line would not fail or, if it did, the likelihood that the specifically affected portion of the ESW system (i.e., containment cooler coil discharge) is not required for a feedwater line break.
Resolution:
S&L has partially responded, addressing the situation identified as involving direct impingement on an ESW line. The response clarified the FSAR intent that only certain portions of the ESW system may be required to remain functional depending on the response required for each potential break.
11 (1190o)
S&L evaluated the resultant sequence of events after the postulated break addressed, and concluded that the affected portion of the ESW system is not essential for the break postulated.
Based on the additional information provided by S&L, the IDR team has evaluated the situation and has accepted the basic S&L conclusion that the existing design is adequate for the situation addressed.
This Observation is still under review for the remaining CCW system situation, pending receipt of additional information from S&L and evaluation of the design process (see Section 2.2 of this report).
2.4 DC CLASS 1E DISTRIBUTION SYSTEM No Observation Reports for items resulting from consideration of HELB/MELB effects on the de system have been issued.
2.5 COMMON REQUIREMENTS No Observation Reports for items resulting from consideration of common requirements for HELB/MELB effects on the systems in the IDR scope have been issued.
2.6 GENERAL ASSESSMENTS l
Due to the incomplete st atus of the HELB/MELB review, and of resolution of the single Observation Report generated to date, it is premature to 12 (1190o)
draw general observations or conclusions at this time. However, based on the review perfonned thus far, this evaluation has identified no significant deficiencies regarding confonnance to licensing commitments /
design requirements. Similarly, in the area of design adequacy, the review of protection provided the selected systems against pipe whip both inside containment and in the auxiliary building as well as that for jet effects outside containment have identified no deficiencies.
Inside containment, however, the single situation in OR 8.24 resulting from the review of HELB-associated jet effects on the CCW and ESW systems is still under review. As a result, no conclusions can yet be drawn as to e 4 ather there is a discrepancy here and, if so, what the significance may be. Nevertheless, results covered by this report tend to confinn the general design adequacy of the HELB/MELB design of the reviewed systems of the Byron Station based on work to date.
Conclu fons relative to the adequacy of the overall design process will be drawn in the Final Report, when it is possible to assess the process on the basis of the total review.
