SSES-FSAR QUESTION 123.l Pursuant to General Design Criterion 2,
safety-related structures, systems and components are to be designed for appropriate load combinations arising from accidents and severe natural phenomena.
With regard to the vibratory loads attributed to the feedback of hydrodynamic loads from the pressure suppression pool of the containment, the staff requires that safety-related mechanical, electrical, instrumentation and control equipment be designed and qu~lified to withstand effects of hydrodynamic vibratory loads associated with either safety relief valve (SRV) discharge of LOCA blowdown into the pressure suppression containment combined with the effects of dynamic loads arising from earthquakes.
The criteria to be used by the staff to determine the acceptability of your equipment qualification program for seismic and dynamic loads are IEEE Std. 344-1975 as supplemented by Regulatory Guides 1.100 and 1.92, and Standard Review Plan Sections 3.9.2 and 3.10. State the extent to which the equipment in your plant meets these requirements and the above requirements to combine seismic and hydrodynamic vibratory loads.
For equipment that does not meet these requirements provide justification for the use of other criteria.
RESPONSE
I.
.laQ£ For Susquehanna
- Project, all BOP Safety related mechanical, electrical, instrumentation and control equipment located inside Primary Containment, Reactor and Control buildings, is being qualified for Seismic loads in combination with hydrodynamic vibratory loads associated with SRV discharge and LOCA blowdown.
Although the SRSS method of combination of seismic and hydrodynamic loads is acceptable, for the project to be conservative, the loads are combined by absolute sum method.
The cases which have deviations from the absolute sum method of combination will be identified in the qualification reports.
The criteria for the qualification of BOP equipment for seismic loads is described in Section 3. 7b. 3 of the FSAR.
The criteria for load combinations and methodology for the design assessment and qualification of Safety related BOP equipment for seismic and hydrodynamic loads have been described in Sections 5.7 and 7.1.7 of the Design Assessment Report (DAR) Rev. 2.
Basically the requirements of IEEE Std. 344-1975 as Rev. 46, 06/93 123.l*l
SSES-FSAR Supplemented by Regulatory guides 1.100 and 1. 92 and SRP Sections 3. 9. 2 and 3.10 are covered in the criteria with the following exception for spatial combination of three components of dynamic motion as stated in Sect ion
?.1.7.1.3 of the DAR.
The criteria states nthe response at any point is the maximum value obtained by adding the response due to vertical dynamic load with the larger value of the responses due to one of the horizontal dynamic loads by the absolute sum method."
All Susquehanna BOP equipment is being qualified for the criteria discussed above.
II.
NSSS LOAD COMBINATIONS:
These were transmitted to the NRC on 8/28/80 as Page 3 of Attachment N to PLA-536. This was in response to NRC Question 110.42.
IMPLEMENTATION OF LOAD COMBINATIONS:
The GE SQRT Program uses outputs from the GE Equipment Adequacy Evaluation Program which combines dynamic loads by SSES as accepted by the NRC in NUREG-0484.
The individual items associated with the load combinations are added as described below:
Steady State Events (e.g., Dead Load, Pressure)
Absolute Sum Time Varying Components (e.g., Maximum Seismic, Maximum Hydrodynamic} - SRSS Components of Events (e.g., Maximum X-Load Due to Y-Earthquake) - SRSS Modal Response-SRSS, except for closely spaced modes where effects are combined by Absolute Sum, Double Sum, or Grouping.
Details for each item of equipment are contained in that equipment's Design Record File which is available for audit.

Rev. 46, 06/93 123.2-2
SSES-FSAR QUESTION 123.3 Identify those items of nuclear steam supply system and balance-of-plant equipment requiring reevaluation and specify why reevaluation is necessary (i.e. because the original qualification used the single frequency, single axis methodology, because equipment is affected by hydrodynamic loads, or because both of the above conditions were present) for each item of equipment.
RESPONSE
Originally almost all Safety related BOP equipments for Susquehanna had been qualified for only Seismic loads.
This equipment has been re-evaluated due to the inclusion of new hydrodynamic (SRV & LOCA) loads, and are being re-qualified with respect to the criteria described in DAR Section 7.17.
The qualification program for the BOP Safety related equipment is being executed in the following four phases.
Phase-I: oualification of Egµipment for Only Seismic Loads:
The only known dynamic load at the time of execution of this phase of the program was Seismic loads. During this phase, the vendors supplying the equipment were required to qualify the equipment in accordance with the requirements specified in FSAR Subsection 3.7b.3.
Phase-II:
Evaluation for Combined Seismic and Hydrodynamic (SRV & LOCA) Loads; This phase was undertaken to evaluate if the existing Seismic qualification of all Safety related BOP equipment could be extended to the combined Seismic and hydrodynamic loads. The criteria used for the re-evaluation is described in DAR Section 7.1. 7.
The general problem areas identified during this evaluation and the proposed action to mitigate these problems are shown below.
Problem Additional hydrodynamic loads Flexibility of equipment Support not considered Rev. 46, 06/93 123.3-1 Retest and/or reanalysis.
Modifications to equipment of their supports if required.
Provide response spectre considering support flexibility
SSES-FSAR Inadequate Modelling Inadequate Testing Phase III: Regualification Efforts:
Include Support Conditions during analysis or testing.
Correct during reanalysis.
Retest.
Qualification by analysis.
Specifically, the Problem areas identified in the previous phase are resolved during this phase by taking appropriate actions.
The requalif ication reports demonstrate that the criteria of DAR Section 7.1.7 have been complied with.
Phase IV: Modifications to Equipment or Equipment Supports:
Equipment or their Supports needing modifications identified during the regulations efforts of Phase III are executed during this phase.

SSES-FSAR QUESTION 123.4 Describe the methods and criteria used to determine the acceptability of the original equipment qualification to meet the required response spectra of item 2. (iii). - 123.2 (iii).
RESPONSE
I.
BOP For cases where the original spectra for which an equipment was qualified enveloped the combined Seismic and hydrodynamic load spectra of Item 123.2 (iii), the equipment is considered qualified. Otherwise (which is true for most cases) the equipment is requalified for the combined spectra to meet the criteria discussed in response to Questions 123.1.
These criteria are described in Section 7.1.7 of the Design Assessment Report.
II.
NSSS The methods and criteria used to determine the acceptability of the original equipment qualification may be found in General Electric Company's Proprietary reports:
NEDE-24788, "Seismic Qualification Review Team (SQRT) Technical Approach for Re-Evaluation of BWR 4/S Equipment"; and NEDE-25250 "Generic Criteria For High-Frequency cutoff of BWR Equipment."

SSES-FSAR QUESTION 123.5 Describe the methods and criteria used to address the vibration fatigue cycle effects on the affected equipment due to required loading conditions.
RESPONSE
I.
~
As described in Subsection 3.7b.3.2 general, the design of equipment is controlled since the number of cycles in is low.
of
- FSAR, in not fatigue an earthquake For combined Seismic and hydrodynamic loads for equipment qualified by analysis, the fatigue effects are implicitly considered since the stresses due to SRV (which are generally controlling for fatigue) are a small contribution to the overall equipment stresses.
Fatigue effects in BOP equipment qualified by testing are accounted for by repetition of the tests.
Typically tests are done for 5 OBE (or 5 upset conditions, i.e., OBE + SRV + LOCA) followed by 1 SSE (or 1 faulted condition, i.e., SSE+ SRV + LOCA) in each of front-to-back/vertical and side-to-side/vertical biaxial configurations. In addition, on some selected pieces of equipment, vibratory table testing is carried out for an extended duration of time (such as 30 to 60 minutes) beyond the combined loading test.
The input motions for the extended du rat ion tests will be such that the generated test response spectra for any segment of the extended duration tests will envelope the SRV spectra. Furthermore, it will be ascertained that the equipment performs its intended function before, during and after the vibratory table tests. The results of the extended duration tests will be documented in the respective qualification reports.
II.
NSSS Vibration fatigue cycle effects for NSSS equipment designed to ASME code requirements was reviewed at GE by NRC consultants from Battelle Pacific Northwest Laboratories on October 7, 1980.
The consultants stated satisfaction with the GE approach which encompasses OBE, SRV, thermal and pressure cycles.
Rev. 46, 06/93 123.5-1
SSES-FSAR Non-ASME Code components qualified by test address the "strong motion" phase of seismic and SRV dynamic motion sufficient to generate maximum equipment response.
These loads are controlling.
GE testing generally consists of 5 upset and 1 faulted test of 30 seconds each which is about 50% greater than required to address strong motion vibration.
Non-ASME Code components qualified by analysis generally have not, in the past, had to address vibration fatigue cycle effects.
In most cases, such effects are not now part of the qualification record.
Rev. 46, 06/93 123.5-2
SSES-FSAR QUESTION 123.6 Based on the methods and criteria described in items 4 and 5, provide the results of the review of the original equipment qualification with identification of (1) equipment which has failed to meet the required response spectra and required requalification, and (2) equipment which was found acceptable, together with the necessary information to justify the adequacy of the original qualification.
RESPONSE
I.
BOP For cases where the original seismic reports can be extended to qualify an equipment for combined seismic and hydrodynamic loads by inspection and subsequent concurrence by vendor, such documents form a part of the qualification package.
The following pieces of equipment bought under the indicated purchase order (P.O.) fall into this category:
(1)
Cooling and chilled water pumps (P.O. #M-327)
(2)
Expansion Tanks and Air Separator Tanks (P.O. #M-302)
{3)
Nitrogen Gas Accumulators (P.O. #M-156)
The rest of the BOP equipment is being qualified for the criteria described in Section 7.1.7 of the Design Assessment Report. The qualification reports for this equipment will provide the appropriate documentation.

SSES-FSAR QUESTION 123.8 Describe plans for a confirmatory in-situ impedance test and an in-plant SRV test program or other alternatives to characterize the ability of equipment to accommodate hydrodynamic loading.
RESPONSE:*
In situ tests are being performed for the determination of structural dynamic characteristics of the equipment for in-service condition.
This in-situ information is being used as supporting evidence for (a) validating a mathematical model for qualification by analysis, or (b) simulating the in-service condition on the vibratory table tests for qualification by testing.
The results and the usage of in-situ testing will be described in the respective qualification reports, whenever such tests are performed.
All safety related BOP equipment for Susquehanna project is being qualified £or combined seismic and hydrodynamic loads for the criteria described in Section 7.1.7 of DAR.
Susquehanna has no plans to perform an in-plant SRV test for equipment qualifications.
An air bubble test was conducted in the suppression pool in an attempt to simulate the effects of an SRV air clearing transient load.
The data from this test are being studied in an effort to determine the extent of conservations in the analytical prediction of applied hydrodynamics loads.
Rev. 46, 06/93 123.8-1
SSES-FSAR QUESTION 123.9 To confirm the extent to which the safety related equipment meets the requirements of General Design Criterion 2, the Seismic Qualification Review Team {SQRT} will conduct a plant site review. For selected equipment, SQRT will review the combined required response spectra (RRS) or the combined dynamic response, examine the equipment configuration and mounting, and then determine whether the test or analysis which has been conducted demonstrates compliance with the RRS if the equipment was qualified by test, or the acceptable analytical criteria if qualified by analysis.
The staff requires that a "Qualification Summary of Equipment" as shown on the attached pages be prepared for each selected piece of equipment and submitted to the staff two weeks prior to the plant site visit.
The applicant should make available at the plant site for SQRT review all the pertinent documents and reports of the qualification for the selected equipment.
After the visit, the applicant should be prepared to submit certain selected documents and reports for further staff review.
RESPONSE
Susquehanna SQRT pre-visit information required for the SQRT site review has been submitted for all BOP and NSSS equipment.
"Qualification Summary of Equipment" and the pertinent documents, reports, vendor prints and all necessary information as required are available for SQRT review.
