LOCATION The plant site is located north (2.5 miles) of Parr, South Carolina. | |||
Parr is the site of existing fossil and hydro power stations operated by SCE&G and the decommissioned, experimental Carolinas Virginia Tube Reac tor (CVTR). The nucl ear plant site is adjacent to a manmade reserv oir created by placing a se ries of dams across Frees Creek, a tributary of the Broad River in western Fairfield C ounty, South Carolina. The resulting Monticello Reservoir provides wate r requirements for the nuclear station and a pumped storage facility. The reservoir is loca ted east of the Broad River and west of South Carolina State Highway 215, about 26 miles north of Columbia, South Carolina. The pumped storage facility raises and lowers the reservoir level approximately 4.5 feet when in operation. | Parr is the site of existing fossil and hydro power stations operated by SCE&G and the decommissioned, experimental Carolinas Virginia Tube Reac tor (CVTR).

99-01 1.5-2Reformatted PerAmendment 99-011.5.1VERIFICATION TESTS (17 x 17)The design of the reactor uses a 17 x 17 square array of fuel rods and thimbles in a fuelassembly and is conceptually similar to, but geometrically different from, the 15 x 15array used in previous designs. The 17 x 17 design is considered to be a relatively small extrapolation of the 15 x 15 design. Comprehensive testing has been performed to verify that the extrapolation is sufficiently conservative. Westinghouse maintains that no plant need be designated a prototype andinstrumented to verify the 17 x 17 fuel design. The change in flow induced vibrationresponse of the internals from a 15 x 15 to a 17 x 17 fuel design will be minimal for the following reasons:1.The only structural changes in the internals, other than the fuel assemblies,resulting from the design change from the 15 x 15 to the 17 x 17 fuel assembly arethe guide tube and control rod drive line.2.The guide tube is rigidly attached at the upper core support plate only. The uppercore plate serves only to align the guide tubes. Because of this type of supportarrangement, the guide tube has a minimal contribution to the vibrational responseof the core barrel and other internal components.3.The effective flow area of the 17 x 17 guide tube is essentially the same as that ofthe 15 x 15 guide tube and therefore, there are no significant differences in the flowdistribution in the upper plenum.4.The fuel assembly lateral spring rate was found by applying loads at various gridlocations with both nozzles restrained. This test assures that the effects of the fuelon the vibrational response of the reactor internals will remain essentially unchanged between the 15 x 15 and the 17 x 17 fuel assembly design because of the small variance of mass and spring rate between the tow designs. The preoperational hot functional flow testing presented in Chapter 14 is considered the most conservative test condition since higher flowrates exist.Some of the verification work described herein was conducted using 17 x 17 assemblies of seven grid design whereas, the selected 17 x 17 assembly design has eight grids.Tabulated below are those 17 x 17 tests which utilized a seven grid geometry and the effect of adding an eighth grid. | 99-01 1.5-2Reformatted PerAmendment 99-011.5.1VERIFICATION TESTS (17 x 17)The design of the reactor uses a 17 x 17 square array of fuel rods and thimbles in a fuelassembly and is conceptually similar to, but geometrically different from, the 15 x 15array used in previous designs.

Westinghouse maintains that no plant need be designated a prototype andinstrumented to verify the 17 x 17 fuel design. The change in flow induced vibrationresponse of the internals from a 15 x 15 to a 17 x 17 fuel design will be minimal for the following reasons:1.The only structural changes in the internals, other than the fuel assemblies,resulting from the design change from the 15 x 15 to the 17 x 17 fuel assembly arethe guide tube and control rod drive line.2.The guide tube is rigidly attached at the upper core support plate only. The uppercore plate serves only to align the guide tubes. Because of this type of supportarrangement, the guide tube has a minimal contribution to the vibrational responseof the core barrel and other internal components.3.The effective flow area of the 17 x 17 guide tube is essentially the same as that ofthe 15 x 15 guide tube and therefore, there are no significant differences in the flowdistribution in the upper plenum.4.The fuel assembly lateral spring rate was found by applying loads at various gridlocations with both nozzles restrained. This test assures that the effects of the fuelon the vibrational response of the reactor internals will remain essentially unchanged between the 15 x 15 and the 17 x 17 fuel assembly design because of the small variance of mass and spring rate between the tow designs. The preoperational hot functional flow testing presented in Chapter 14 is considered the most conservative test condition since higher flowrates exist.Some of the verification work described herein was conducted using 17 x 17 assemblies of seven grid design whereas, the selected 17 x 17 assembly design has eight grids.Tabulated below are those 17 x 17 tests which utilized a seven grid geometry and the effect of adding an eighth grid. | ||

The 17 x 17 spider supports 24 rodlets (the 15 x 15design supports 20) with no vane supporting more than two rodlets (same as the 15 x 15 design).The rod cluster control spider tests verified the structural adequacy of the design. Thespider vane to hub joint was tested for structural adequacy by:1.Vertical static load test to failure, and2.Vertical fatigue test to approximately 3.0 x 10 6 steps.The static load test was performed by applying tensile and compressive loads to thespider. The load was applied parallel to the spider hub and reacted between the spiderhub and fingers. The spider fingers shared the load equally. The number of cycles for the fatigue test was determined from the expected number of steps a control rod drive mechanism would experience during 20 years in a load follow reactor (1.5 x 10 6 steps).The test met the recommended cyclic test requirements of the ASME Code, Section III, Appendix II, paragraph 1520.The spring pack within the spider hub was tested to determine the spring load deflectioncharacteristic as a function of the loading cycles seen by the spring. The test wasterminated after 1000 cycles compared to a 400 cycle (rod drop) design value. The test loads were equal to or greater than that predicted to result in spring material yielding. | 1.5-4Reformatted PerAmendment 99-011.5.1.1Rod Cluster Control Spider Tests1.5.1.1.1Test Purpose and ParametersThe 17 x 17 rod cluster control spider is conceptually similar to, but geometricallydifferent from, the 15 x 15 spider.

Typical of this type of testingare the two discussed below, which were recently completed:1.Emergency Core Cooling Flow DistributionA 10 x 10 rod bundle was installed in a plastic housing with a water supply at thetop. A grid collection unit at the bottom of the bundle collected the water as itflowed through the model and diverted it to the measuring tubes at the base. | ||
Knowledge of the flow distribution in the bundle was obtained in this manner.2.Sample System Mixing TestThis test used one thermocouple to measure the temperature of water from four locations in a reactor. The purpose of the procedure was to determine whether theindication from the single thermocouple was representative of the average temperature of the four water supplies. A mock-up of the mixing chamber was constructed so that hot or cold water (at closely controlled pressure) could besupplied to any of the four inlets. By running combinations of hot and cold inlets and making simultaneous recordings of the various temperatures, highly useful information was obtained. | Knowledge of the flow distribution in the bundle was obtained in this manner.2.Sample System Mixing TestThis test used one thermocouple to measure the temperature of water from four locations in a reactor.

1.1-1 Reformatted Per Amendment 99-01 FSAR NOTE With the exception of the description of 10CFR50.2 design basis parameters, numerical values throughout this FSAR should be considered nominal in nature. They are intended to provide a sense for the value of the parameter and should NOT be viewed
as an actual value observable in the plant.
Plant operation at va lues other than those presented herein is acceptable. The actual values are documented within established Technical Specification, Desi gn Basis Documentation, or other controlled documents.
1.0 INTRODUCTION
AND GENERAL DESCRIPTION OF PLANT NOTE 1.1 Section 1.1 is being retained for historical purposes only.
1.1 INTRODUCTION
This Final Safety Analysis Report is submitted in support of an application by South Carolina Electric and Gas Company (SCE&G) for a class 103 license to operate a
nuclear power station designated as the Virg il C. Summer Nuclear Station. This report presents descriptions and analyses of the final station design.
1.1.1 STATION
LOCATION The plant site is located north (2.5 miles) of Parr, South Carolina.
Parr is the site of existing fossil and hydro power stations operated by SCE&G and the decommissioned, experimental Carolinas Virginia Tube Reac tor (CVTR). The nucl ear plant site is adjacent to a manmade reserv oir created by placing a se ries of dams across Frees Creek, a tributary of the Broad River in western Fairfield C ounty, South Carolina. The resulting Monticello Reservoir provides wate r requirements for the nuclear station and a pumped storage facility. The reservoir is loca ted east of the Broad River and west of South Carolina State Highway 215, about 26 miles north of Columbia, South Carolina. The pumped storage facility raises and lowers the reservoir level approximately 4.5 feet when in operation.
1.1.2 NUCLEAR
STEAM SUPPLY SYSTEM The station includes a pressurized water reactor nuclear steam supply system (NSSS), designed and furnished by Westinghouse Elec tric Corporation and a turbine generator, designed and furnished by General Electric Company. This equipment is similar in design to several projects licensed or current ly under review by the Nuclear Regulatory Commission (see Section 1.3). The balance of the station is des igned and constructed by SCE&G, with the assistance of it s agent, Gilbert Associates, Inc.
99-01 02-01 1.1-2 Reformatted Per Amendment 99-01 1.1.3 CONTAINMENT Containment is provided by the Reactor Building, a reinforced concrete structure designed by Gilbert Associates, Inc. The Reactor Building is comprised of a flat foundation mat, cylindrical wa ll and shallow dome roof. The foundation mat and cylindrical wall are reinforced with conventional mild steel reinforcing. The cylindrical wall is prestressed in the vertical and horizon tal directions by a post-tensioning system.
The shallow dome roof is prestressed by a three-way post-tensioning system. The inside surface of the Reactor Building is li ned with a carbon steel liner to ensure a high degree of leak tightness under operating and accident conditions.
1.1.4 CORE THERMAL POWER LEVELS The NSSS is designed for a rated power output of 2912 MWt, which is the license application rating, with an equivale nt station net electrical output of approximately 950 MWe. Containment and engineered safety features are designed and evaluated for operation based upon an Engineered Safety Design Rating (ESDR) and Licensed Power Level of 2900 MWt in the core.
Postulated accidents having offsite dose consequences are evaluated at 2900 MWt. A nalyses of all accident consequences, to show conformance to 10CFR50.46, have been performed at 2900 MWt. Conformance to 10CFR50.46 for Large Break LOCA is evaluated at 2900 MWt, the rated core power level following Refueling 9 in the Spring of 1996.
1.1.5 SCHEDULE
The project schedule is based upon plant completi on (to fuel loading) in February, 1982 and commencement of commercial operation appr oximately six months after issuance of the operating license.

1.5-1Reformatted PerAmendment 99-01NOTE 1.5Section 1.5 is being retained for historical purposes only.1.5REQUIREMENTS FOR FURTHER TECHNICAL INFORMATIONReference [1] presents descriptions of the safety-related research and developmentprograms which are being carried out for, or by, or in conjunction with, Westinghouse Nuclear Energy Systems, and which are applicable to Westinghouse Pressurized Water Reactors.For each program described in this section and still in progress, the safety-relatedprogram is first introduced, followed, where appropriate, by background information.There is, then, a description of the program which relates the program objectives to the problem and presents pertinent recent results. Finally, an alternate position may be given for programs (generally experimental rather than analytical) which have not yet reached a stage where it is reasonably certain that the results confirm the expectation.
The alternate position is one that might be used if the results are unfavorable; it is not necessarily the only course that might be taken.The term "research and development", as used in this section, is the same as that usedby the Commission in Section 50.2 of its regulations, that is:(n)"Research and development" means (1) theoretical analysis, exploration, orexperimentation; or (2) the extension of investigative findings and theories ofa scientific nature into practical application for experimental and demonstration purposes, including the experimental production and testing of models, devices, equipment, materials, and processes.The technical information generated by these research and development programs will be used either to demonstrate the safety of the design and more sharply define marginsof conservatism, or will lead to design improvements.Progress in these development programs will be reported on a timely basis. New safety-related research and development programs, which include existing programswhich become safety-related, will also be described.Included in the overall research and development effort are the programs below whichare applicable to the 17 x 17 fuel assembly. The test programs were completed during1975 in order to support the initial loading of the first 17 x 17 fuel in late 1975.
99-01 1.5-2Reformatted PerAmendment 99-011.5.1VERIFICATION TESTS (17 x 17)The design of the reactor uses a 17 x 17 square array of fuel rods and thimbles in a fuelassembly and is conceptually similar to, but geometrically different from, the 15 x 15array used in previous designs. The 17 x 17 design is considered to be a relatively small extrapolation of the 15 x 15 design. Comprehensive testing has been performed to verify that the extrapolation is sufficiently conservative. Westinghouse maintains that no plant need be designated a prototype andinstrumented to verify the 17 x 17 fuel design. The change in flow induced vibrationresponse of the internals from a 15 x 15 to a 17 x 17 fuel design will be minimal for the following reasons:1.The only structural changes in the internals, other than the fuel assemblies,resulting from the design change from the 15 x 15 to the 17 x 17 fuel assembly arethe guide tube and control rod drive line.2.The guide tube is rigidly attached at the upper core support plate only. The uppercore plate serves only to align the guide tubes. Because of this type of supportarrangement, the guide tube has a minimal contribution to the vibrational responseof the core barrel and other internal components.3.The effective flow area of the 17 x 17 guide tube is essentially the same as that ofthe 15 x 15 guide tube and therefore, there are no significant differences in the flowdistribution in the upper plenum.4.The fuel assembly lateral spring rate was found by applying loads at various gridlocations with both nozzles restrained. This test assures that the effects of the fuelon the vibrational response of the reactor internals will remain essentially unchanged between the 15 x 15 and the 17 x 17 fuel assembly design because of the small variance of mass and spring rate between the tow designs. The preoperational hot functional flow testing presented in Chapter 14 is considered the most conservative test condition since higher flowrates exist.Some of the verification work described herein was conducted using 17 x 17 assemblies of seven grid design whereas, the selected 17 x 17 assembly design has eight grids.Tabulated below are those 17 x 17 tests which utilized a seven grid geometry and the effect of adding an eighth grid.

1.5-4Reformatted PerAmendment 99-011.5.1.1Rod Cluster Control Spider Tests1.5.1.1.1Test Purpose and ParametersThe 17 x 17 rod cluster control spider is conceptually similar to, but geometricallydifferent from, the 15 x 15 spider. The 17 x 17 spider supports 24 rodlets (the 15 x 15design supports 20) with no vane supporting more than two rodlets (same as the 15 x 15 design).The rod cluster control spider tests verified the structural adequacy of the design. Thespider vane to hub joint was tested for structural adequacy by:1.Vertical static load test to failure, and2.Vertical fatigue test to approximately 3.0 x 10 6 steps.The static load test was performed by applying tensile and compressive loads to thespider. The load was applied parallel to the spider hub and reacted between the spiderhub and fingers. The spider fingers shared the load equally. The number of cycles for the fatigue test was determined from the expected number of steps a control rod drive mechanism would experience during 20 years in a load follow reactor (1.5 x 10 6 steps).The test met the recommended cyclic test requirements of the ASME Code,Section III, Appendix II, paragraph 1520.The spring pack within the spider hub was tested to determine the spring load deflectioncharacteristic as a function of the loading cycles seen by the spring. The test wasterminated after 1000 cycles compared to a 400 cycle (rod drop) design value. The test loads were equal to or greater than that predicted to result in spring material yielding.
These loads were in excess of the design values. The test acceptance criterion was for the spring to retain adequate preload after the repeated cycling.1.5.1.1.2FacilityThe 17 x 17 spider tests were performed at the Westinghouse Engineering MechanicsLaboratory (see Section 1.5.3.2.15).1.5.1.1.3StatusSpider tests have been completed. A vertical static load test approximately seven timesthe design dynamic load did not result in spider vane to hub joint failure. A spider wastested to 2.8 x 10 6 steps without failure. The spider loading was 110 percent of thedesign value for 1.8 x 10 6 cycles and 220 percent of the design loading for 1 x 10 6cycles. Design load is 3600 pounds compression and 1800 pounds tension. The spring test resulted in negligible preload loss.
1.5-5Reformatted PerAmendment 99-011.5.1.2Grid Tests1.5.1.2.1Test Purpose and ParametersThe 17 x 17 grid is conceptually similar to, but geometrically different from the 15 x 15"R" grid. The purpose of the grid tests is to verify the structural adequacy of the griddesign.Load deflection tests have been made on the grid spring and dimple. Grid spring radial(normal) stiffness and the grid dimple radial and tangential stiffness were obtained. Thisinformation was used to verify that the fuel rod clad wear evaluation has been based on conservative values of these parameters. The fuel rod wear evaluation is conservative as shown by the flow test results presented in Reference [3].The grid buckling strength has been determined from tests using both static anddynamic loads. The loads were applied uniformly to the face of the outside strap,transmitted directly through the grid and reacted at the grid face opposite the input. A description of the grid impact test along with a description of the analytical use of the test parameters is given in Reference [2]. These tests are used to verify that grid buckling during a postulated seismic occurrence does not interfere with control rod insertion.1.5.1.2.2FacilityThe grid tests were conducted at the Westinghouse Engineering Mechanics Laboratory(see Section 1.5.3.2.15).1.5.1.2.3StatusThe grid tests have been completed. Test results are in agreement with pretest designvalues. The test results, along with fuel assembly structural test results, were factoredinto the seismic analysis [2].1.5.1.3Fuel Assembly Structural Tests1.5.1.3.1Test Purpose and ParametersThe 17 x 17 fuel assembly tests were performed to determine mechanical strength andproperties. The fuel assembly parameters obtained were as follows:1.Lateral and axial stiffness.2.Impact and internal structural damping coefficients.3.Vibrational characteristics.4.Lateral and axial impact response for postulated accident loads.
1.5-6Reformatted PerAmendment 99-01The parameters obtained from the lateral dynamic tests are used for seismic analysis,while those obtained from the axial tests are incorporated in the loss of coolant (blowdown) accident analysis. The remaining tests are primarily to demonstrate that the assembly has sufficient mechanical strength to preclude damage during shipment, normal handling, and normal operation.The fuel assembly is subjected to both lateral and axial loads to obtain the respectivestatic axial and lateral stiffnesses. The information obtained from these tests is used toestablish parameters primarily for accident analysis since these conditions appear limiting. The axially applied loads, which were well in excess of shipment, normal handling and normal operational design loads, did not result in any fuel assembly permanent deformation or damage.Static loads were incrementally applied to the fuel assembly to determine its lateralstiffness. The tests were accomplished with both nozzles fixed in place and forcesapplied to various grids.The fuel assembly was dynamically tested in a vertical position using core pins tosimulate reactor support conditions. An electrodynamic shaker was attached to thecenter (4th) grid to provide excitation. The fuel assembly mode shapes and corresponding natural frequencies were obtained from displacement transducers. A comparison of analytical and experimental results is given in Reference [2].
Experimental vibrational studies of individual fuel rods were also performed. The rods were tested under simulated fuel assembly support conditions and as assembled in a prototype fuel assembly. The information obtained from these tests included the fundamental frequencies and mode shapes. A general test description and a summary of the results is presented in Reference [3].The fuel assembly axial stiffness was found by incrementally increasing the static load(compressive) and then incrementally decreasing the static load.Lateral impact tests were performed by displacing the center of the assembly with the nozzles fixed in place. The assembly was released and allowed to impact on lateralrestraints at each of the five center grid locations.The axial impact response and damping were found by dropping the fuel assembly fromvarious heights. The axial impact test was performed with the fuel assembly in theupright position.
1.5-7Reformatted PerAmendment 99-01The relevant parameters measured during the lateral and axial impact tests are asfollows:1.Impact duration versus impact load.
2.Impact force versus drop height or initial displacement.
3.Impact damping or restitution as a function of impact force.
A general description of the test procedure, including a description of use of theparameters as related to accident analysis is presented in Reference [2].There is a general axial test buckling criterion which does not allow local buckling of components which could preclude control rod insertion during an accident. The fuelassembly overall buckling and component local buckling is checked during the axial static and dynamic tests. The lateral displacement associated with the fuel assembly overall (beam type) buckling is limited by the reactor internals clearances and therefore buckling does not reduce the fuel assembly ultimate strength. Local component buckling was not experienced during either the static or dynamic tests for loads well in excess of the design values. The general acceptance criteria was not violated.1.5.1.3.2FacilityThese tests were conducted at the Westinghouse Engineering Mechanics Laboratory(see Section 1.5.3.2.15).1.5.1.3.3StatusThe fuel assembly structural tests have been completed. The fuel assembly structuraltest results are factored into the seismic and blowdown analyses [2].1.5.1.4Guide Tube TestsA new guide tube was designed to accommodate the 24 rodlet pattern adopted for 17 x 17 cores. This guide tube is sufficiently strong to provide increased margins of safety over present guide tubes. The main features of the new design are full length enclosures and cylindrical upper enclosures. The 17 x 17 (24 rodlet) pattern reduced the central area available for driveline passage significantly, thus necessitating a generally tighter design of the rod guidance elements.The following guide tube tests are considered as engineering tests.

1.5.1.5Engineering Prototype Assembly Tests1.5.1.5.1Test Purpose and ParametersThe purpose of these tests was to demonstrate that the 17 x 17 fuel assembly anddriveline hardware designs perform as predicted. These tests were run prior to therequired plant functional tests and are used as an engineering information test to obtain experimental data. A single set of driveline hardware, including control rods, was used in the tests. The fuel assemblies and driveline were subjected to flow and system conditions covering those most likely to occur in a plant during normal operation as well as during a pump overspeed transient.These tests are used to verify, from an engineering confidence standpoint, theintegrated fuel assembly and rod cluster control performance in several areas. Dataobtained included pressures and pressure drops throughout the system, hydraulic loadings on the fuel assembly and driveline, control rod drop time and stall velocity, fuel rod vibration and control rod, driveline, guide tube, and guide thimble wear during a lifetime of operation. None of this information is considered to be safety-related.Specifically, two full size 17 x 17 fuel assemblies (one for Phase I and one for Phase IIand III testing), one control rod, drive shaft and control rod drive mechanism wereinstalled and tested in the 24 inch inside diameter x 40 foot high D-Loop at the Westinghouse Test Engineering Laboratory Facility.1.5.1.5.1.1Fuel Assembly Life Test (Phase I)The first fuel assembly was subjected to the maximum expected control rod travelduring one fuel assembly lifetime. The nominal test conditions were a flow velocitybased on the design flowrate, a temperature of 585°F and a pressure of 2000 psig.
These conditions represent an extreme set of conditions.Using an instrumented 17 x 17 prototype fuel assembly, guide tube and rod clustercontrol drive assembly, the tests conducted in the D-Loop obtained information on thefollowing:1.Mechanical integrity and performance 2.Drop time 1.5-9Reformatted PerAmendment 99-013.Fuel rod vibration4.Control rod velocity 5.Hydraulic lift force 6.Guide thimble dashpot pressure Following this, the prototype fuel assembly underwent a complete post test evaluationand the guide tubes and driveline were inspected for any abnormal wear conditions.The purpose of this test was basically to determine the effect of the 17 x 17 fuel assembly and control rod configuration of Items 1 through 6 in Phase I and Items 1 and 2 in Phases II and III. The effect on control rod drop due to a seismic disturbance is evaluated analytically.1.5.1.5.1.2Guide Tube and Rod Cluster Control Life Test (Phase II and Phase III)The second fuel assembly was then installed to continue the test at the same flow andtemperature until 3,000,000 total steps of the driveline were accumulated. For PhasesII and III, testing was run at temperatures between 100°F and 585°F and at flowrates from 50 percent to 140 percent of the design flowrate.The test included a program of control rod drops and mechanism stepping thatapproximates the driveline duty for the design lifetime of an operating plant (Phase II).Specifically, approximately 1,275,000 mechanism steps and approximately 270 control rod drops were accumulated. The components were then inspected. Following inspections, testing was continued until a total of 3,000,000 mechanism steps and approximately 500 control rod drops were accumulated (Phase III testing).These tests were directed toward:
1.Life wear evaluation 2.Drop time 3.Rod stall characteristics These tests are not safety-related tests; they are used as engineering tools. Finalverification is demonstrated during the precritical rod drop tests.At the completion of Phase II tests, the test assembly was inspected to determine guide tube and driveline wear characteristics. This inspection was repeated at the end of thetest (Phase III).

The results of the testing are given inReferences [3] and [6].1.5.2LOCA HEAT TRANSFER TESTS (17 x 17)1.5.2.117 x 17 Reflood Heat Transfer TestsExtensive experimental programs have recently been performed with a simulated 17 x17 assembly to determine its behavior under Loss of Coolant Accident (LOCA) conditions. The 17 x 17 tests were conducted in the G-Loop facility at theWestinghouse Forest Hills Laboratory.Results from the 17 x 17 programs were compared with data from the 15 x 15 assemblytest programs and were used to confirm predictions made by correlations and codesbased on the 15 x 15 test results (see Reference [7]).1.5.2.2Facility DescriptionThe 17 x 17 test facility provides experimental measurements on the refloodingbehavior of a 17 x 17 rod array following a LOCA. The test assembly consists of an array of 336 electrically heated rods and 25 guide tube thimbles arranged in a 17 x 17 array. The heater rod diameter, the active heated length, and pitch spacing is identical to that used in the 17 x 17 fuel. There were eight Westinghouse production mixing vane grids in the bundle.1.5.2.3Delayed Departure From Nucleate Boiling Testing1.5.2.3.1IntroductionThe NRC Acceptance Criteria for Emergency Core Cooling Systems (ECCS) forLight-Water Power Reactors was issued in Section 50.46 of 10 CFR 50 on December28, 1973. It defines the basis and conservative assumptions to be used in the evaluation of the performance of the ECCS. Westinghouse believes that some of the conservatism of the criteria is associated with the manner in which transient DNB phenomena are treated in the evaluation models. Transient critical heat flux data presented at the 1972 specialist's meeting of the Committee on Reactor Safety Technology (CREST) indicated that the time to DNB can be delayed under transient conditions. To demonstrate the conservatism of the ECCS evaluation models, Westinghouse has initiated a program to experimentally simulate the blowdown phase of a LOCA. This testing is scheduled for the middle of 1976 as part of an Electric Power 1.5-11Reformatted PerAmendment 99-01Research Institute (EPRI) sponsored Blowdown Heat Transfer Program. This programis scheduled for completion at the end of 1976. Development of a transient DNB correlation for use in the Westinghouse ECCS analysis is planned for completion in 1977.1.5.2.3.2ObjectiveThe objective of the delayed departure from nucleate boiling (DDNB) test is todetermine the time that DNB occurs under LOCA conditions. This information will beused to confirm the existing, or develop a new, Westinghouse transient DNB correlation.
The steady-state DNB data obtained from 15 x 15 and 17 x 17 test programs can be used to assure that the minimal geometric differences between the two fuel arrays can be correctly treated in the transient correlations.1.5.2.3.3ProgramThe program is divided into two phases. Phase I simulates PWR behavior during aLOCA to permit definition of the time delay associated with onset of DNB. Tests in thisphase will cover the large double ended guillotine cold leg break. All tests in Phase I are started after establishment of typical steady-state operating conditions. The fluid transient is then initiated, and the rod power decay is programmed in such a manner as to simulate the actual heat input of fuel rods. The test is terminated when the heater rod temperatures reach a predetermined limit (dependent on power level).Typical parameters which can be studied under Phase I testing are shown inTable 1.5-1.Phase II will provide separate effects data to permit heat transfer correlationdevelopment. The Phase II tests will also start from steady-state conditions, with sufficient power tomaintain nucleate boiling throughout the bundle. Controlled ramps of decreasing testsection pressure or flow will initiate DNB. By applying a series of controlled conditions, investigation of the DNB will be studied over a range of qualities and flows and at pressures relevant to a PWR blowdown.Typical parameters which can be studied under Phase II testing are shown inTable 1.5-2.1.5.2.3.4Test DescriptionThe experimental program is being conducted in the J-Loop at the Westinghouse ForestHills Facility with a full length 5 x 5 rod bundle simulating a section of a 15 x 15assembly to determine DNB occurrence under LOCA conditions.
1.5-12Reformatted PerAmendment 99-01The heater rod bundles to be used in this program will be assembled using internallyheated rods and Westinghouse grids. The heater rods are designed for high reliability, long life, and high power density. The maximum power is 18.8 kW/ft, and the total power is 135 kW for extended periods over the 12 foot heated length of the rod. Heat is generated internally by means of a varying cross-section, rugged, tubular resistor which approximates a U 2 cos U power distribution, skewed to the bottom. Each rod isadequately instrumented with a total of 20 thermocouples (8 resistors and 12 sheath thermocouples).1.5.2.3.5ResultsThe experiments in the DDNB facility will result in cladding temperature and fluidproperties measured as a function of time throughout the blowdown range from 0 to 20seconds.Facility modifications and installation of the initial test bundle have been completed. Aseries of shakedown tests in the J-Loop have been performed. These tests provideddata for instrumentation calibration and check-out, and provided information regarding facility control and performance. Initial program tests were performed during the firsthalf of 1975.1.5.2.4Single Rod Burst TestThe single rod burst test results are used to quantify the maximum assembly flowblockage which is assumed in LOCA analyses.Previously, single rod and multi-rod burst tests have been completed on the 15 x 15 fuelassembly rods under conditions which exist during the LOCA. The conclusion of thesetests was that fuel rods burst in a staggered manner so that maximum average flow area blockage for the assembly is 55 percent during blowdown and 65 percent during reflood, based on the characteristics of the PWR fuel rod and the conservative peak clad temperature predicted during the LOCA transient.The single rod burst test program for the 17 x 17 fuel assembly rods consisted ofbursting specimens at the various internal pressures and heating rates in a steamatmosphere.In addition, tests were run on 15 x 15 fuel assembly rods to assure reproducibility of the1972 single rod burst test results. Results from the program are documented inReferences [8] and [9].
1.5-13Reformatted PerAmendment 99-01The single rod burst tests and evaluation have been completed and are reported inReferences [8] and [9]. Results of the tests showed that the LOCA behavior of the 17 x 17 clad in comparison to that of the 15 x 15 clad exhibited no significant differences in failure ductility. Because of the results and the geometric scaling, the flow blockage
(%) as determined by 15 x 15 multi-rod burst test simulation can be used for the 17 x 17 geometry.1.5.2.5Power-Flow MismatchDesign emphasis has been placed on reliable and effective control and protectionsystems for the reactor core and engineered safety features to ensure adequate margins within incidents can be terminated before the onset of fuel failure. For this reason, investigations into the mechanisms of fuel failure and its propagation, and phenomena of molten fuel-coolant interaction have been limited.Obtaining complete answers to the question related to fuel rod failure will requireextensive testing because of the multiplicity of parameters involved. Such an extensiveinpile test program has been proposed by the Aerojet Nuclear Company under NRC (AEC) sponsorship for the Power Burst Facility (PBF).The proposed PBF program is expected to simulate conditions appropriate to major accidents postulated for reactor systems, i.e., loss of flow, loss of coolant, and reactivityinitiated accidents. Phase I of the proposed PBF program is expected to be completed approximately two years after facility checkout or by mid 1977. Phase I is expected toconcentrate upon establishing the thresholds for and the consequences of fuel failure and utilizes fuel rod clusters of various sizes to determine the extent of failurepropagation. This program would broaden the experimental basis for evaluating reactor safety, but should not be considered essential for the design and safe operation.Westinghouse will closely follow any such experimental program or analytical studiesthat may become available. Until such information is available, clearly demonstratingthat local fuel melting is an acceptable condition, the emphasis in design will continue tobe placed on providing adequate margins to minimize the probability of fuel melting.The margins incorporated in the design within which incidents can be terminated, before the onset of fuel failure, provide a sound basis for safe operation.

Operating temperatures are obtained from the conversion of the pumping power into heat, as well as from external heaters. Typical tests run in these loops are:1.Full scale gate and check valves; 2.Material corrosion-erosion, with variable water chemistry; and 3.Corrosion product release and transport properties of crud.Characteristics of A and B LoopsMaximum Flowrate150 gpm at 300 feetMaximum Pump Head335 feet at 60 gpmMaximum Allowable Temperature 650FNormal Working Pressure2000 psiNormal Working Temperature 600F1.5.3.2.2D-Loop, Medium Flow/High Pressure Hydraulic FacilityThe D-Loop is a flexible test facility used for demonstrating the interplay of reactorsubsystems and evaluating component design concepts. It contains a canned motorpump, which produces a 290 foot head at 3000 gpm. All piping (10 inch Schedule 160)in contact with the primary water is stainless steel. Loop pressure is established and maintained by an air driven charging pump operating in conjunction with a gas loaded back pressure valve. Most of the power required to establish and maintain loop temperature is derived from the circulating pump operation, and 75 kW of heat is available from electric strip heaters.

Flow and vibration studies are conducted with this loop, and, because of its low pressure, plastic models for visual observation or photography may be used. In addition, a four inch Rockwell water meter in a branch line permits the calibration of flow meters up to 800 gpm.Characteristics of E LoopMaximum Flowrate2000 gpm at 130 feet 1000 gpm at 260 feetMaximum Working PressurePump Head1.5.3.2.4G-Loop, Emergency Core Cooling System FacilityThe G-Loop is a high pressure, ECCS test facility designed and fabricated to ASMESection I for 2000 psi and 650°F. It consists of a main test section and vessel, exhaustsystem, piping, separators and muffler, flash chamber steam supply system, and high pressure/low pressure cooling systems.This loop is basically designed to obtain test data for analysis of LOCAs, for breaks upto and including double ended pipe breaks for PWRs. Tests are initiated at simulatedconditions existing 8 seconds after the start of a LOCA. A typical run consists of constant power and pressure, followed by pressure blowdown, power decay and 1.5-17Reformatted PerAmendment 99-01emergency core cooling. The G-Loop is capable of performing the following methods ofemergency core cooling: Current, Upper Head Injection (UHI), UHI w/Current and other Core Spray Systems. It may also be used for constant temperature/pressure small leg break tests (core uncovering tests). These consist of boiling off water at a constant bundle power input until the rods can no longer be cooled.The G-Loop test bundle consists of 480 electrically heated rods, 16 grid supportthimbles, and 33 spray thimbles bounded by an octagonal stainless steel baffle andarranged as per a four-loop 15 x 15 rod bundle configuration. The loop is controlled (fully automated during transients) through a PDP-II-DEC-16K computer with a 600 point Computer Products A-D Converter operating at a sweep rate of 40,000 points per second for data acquisition.

Typical of this type of testingare the two discussed below, which were recently completed:1.Emergency Core Cooling Flow DistributionA 10 x 10 rod bundle was installed in a plastic housing with a water supply at thetop. A grid collection unit at the bottom of the bundle collected the water as itflowed through the model and diverted it to the measuring tubes at the base.
Knowledge of the flow distribution in the bundle was obtained in this manner.2.Sample System Mixing TestThis test used one thermocouple to measure the temperature of water from four locations in a reactor. The purpose of the procedure was to determine whether theindication from the single thermocouple was representative of the average temperature of the four water supplies. A mock-up of the mixing chamber was constructed so that hot or cold water (at closely controlled pressure) could besupplied to any of the four inlets. By running combinations of hot and cold inlets and making simultaneous recordings of the various temperatures, highly useful information was obtained.
1.5-21Reformatted PerAmendment 99-011.5.3.2.11Autoclave TestingThe Test Engineering Laboratory is equipped with autoclaves ranging in size from 1/2gallon to 100 gallons. These devices are in constant use to determine the effect ofvarious water chemistries on core components, as well as to perform corrosion tests.
The units have also been used as boilers to provide steam for miscellaneous development tests, including acoustic leak detection.1.5.3.2.12Mechanical Component and Vibration TestFull scale mechanical and vibration tests are performed at the Test EngineeringLaboratory on plant and reactor components to prove the reliability of equipment design.Vibration testing of reactor components is also performed in the laboratory, using electronically excited shaker heads. Three sizes are available (2 lbs, 50 lbs, and 150 lbs) for regular scale model testing for frequencies from 5 Hz to 50 Hz.1.5.3.2.13Electrical Component AssemblyHighly skilled technicians are available at the Test Engineering Laboratory forconstructing complex control and instrumentation systems. Work is initiated withengineering ideas and sketches, and includes mounting of process controllers, recorders, meters, relay logic, protection circuits, switches and indicators.Point-to-point wiring is used, as required. Final as-built drawings are prepared,inspection and thorough electrical checkout is performed before installation in a facility.1.5.3.2.14Surveillance System DevelopmentSurveillance systems provide on-line monitoring of pressure vessels for flaws.Electronic components are being developed at the Test Engineering Laboratory for anacoustic emission monitoring system for inservice inspection of operating plant vessels and piping. This system is designed to detect and locate initiation and propagation of cracks at various locations, such as welds and stress risers. Vessel flaw growth andrupture data have been obtained through joint programs at the Idaho National Engineering Laboratories and at the Oak Ridge National Laboratories. Pipe rupture data has been obtained from NRC (AEC) sponsored tests, and hydrostatic test data, operational noise and attenuation characteristics have been measured at various Westinghouse operating plants.1.5.3.2.15Engineering Mechanics LaboratoryBench tests are performed in fixtures designed for the particular test using standard testequipment and techniques.
