1. INTRODUCTION i

i ~! The approval in 1981,of the National Energy Plan which foresees : { i the costruction of FWR's power stations for an overall power of i 6000 MWe convinced ENEA ( Comitato nazionale per la ricerca e lo sviluppo dell'energia nucleare e delle energie alternative) to j undertake an experimental programme in the_ safety field in the I frame of which the design and the costruction of an integral i facility simulating the italian FWR is the first main geal. -{ i Such a facility named SPEE : Simulazione Pwr per Esperienze di 1 Sicurezza ) and whose construction started at SIET ( Societa' Informa:icn1 Esperienze Termeldrauliche ) in Rarch 1983.has the I following aies: I - to maintain and to increase knowledge in the field of safety i related technology; - to supply experimental results for accident analysis codes: - to evaluate the effects of the operator interventien on the '!( plant; l 1 - to test possible plant modifications. The SPES is designed to simulate thermal-hydraulic phenomena 4 peculiar to SELOCA's and cperational transients by having the same loop number as the reference reactor by maintaining the prototypical component elevations and by scaling core power and i volume 1/427. t i i f

2. SPES CHARACTERISTICS AND FUNCTIONS.

[ ti t The SPES integral test facility is a scale model of the italian f i PWR ( Westinghouse 313 type, 3 loops 2775 MWth core power ) aiming at the simulation of the thermal-hydraulic phenomena t following SBLOCA's and operational transients occuring in the reference plant. i In particular, SPES system simulates - the whole primary circuit; f r - the secondary system restricted to: . steam generator secondary side, . main feed water lines downstream the isolation valves, j . main steam lines upstream the turbine stop valve; I I - the most significant auxiliary and emergency systems: . charging and letdown systems, i . safety injection systems (HPIS, LPIS, accumulators, EFWS) . steam dump. _} t i t f ?

-. ~. i i h together with other-criteria which concern the preservation, in any SPES component, of the following parameters : f i - fluid thermodynamic conditions ( pressure and enthalpy )- f - power-to-flowrate ratio ; i ' i - transit time of the fluid ; 't I - heat flux. Further scaling criteria were applied to design the individual t SPES components; for example in the components, with fluid flowing l t'l vertically the elevations have been preser"ad to cotain a good i I reproduction of natural circulation phenomena. On the contrary., i in the components where the prevailing flow direction is d horizontal, the Froude numcer conservation has been imposed to t preserve, as much as possible, the flow pattern transition in ? horizontal tubes. f The particular scaling criteria for the main components of the ~ l i SPES loop are now described. 4 + l VESSEL DOWNCOMER i - Vertical elevations are preserved. h f Observations: the downcomer geometry is tubular to obtain the minimum pressure drop distorsion compatible with the volumetric l I criterion and the elevation preservation. f i r i e 3 h 9 -i 4 r

i I I i POWER CHANNEL - Vertical elevations are preserved; ? - the bundle geometry (red pitch and outer diameter) is preserved. t } Observations the vertical elevations are preserved only between j the inlet and outlet nozzles of the fluid, because the lower j i plenum and upper head elevations have no influence on the natural circulation phenomena. ) PRIMARY COOLANT PUMPS 't i 1 - The nominal head is approximately preserved ; .j l - the coastdown behaviour is reproduced. I 1 l i i Cbservatiens : the nominal head may be slightly different in I comparison with the PWR pumps due to some small distorsions in the i i loop pressure drops ; the coastdown behaviour (flowrate transient f with loss of the electric power) is reproduced by providing a suitable flywheel on the pump shaft.Furthermore in particular i i cases (i.e. small break with pumps on) a procedure to establish ~ the pump speed which reproduces the same head and flowrate across the pump nas been defined. .l c b I l f R l 1 l 1 -10 i 1 I .\\

-. ~ h i 'f s f I t STEAM GENERATORS - l 1 i f - Vertical elevations are preserved both in the primary and in the i f secondary side ; I - the bundle geometry (tube pitch, diameter and thickness) is preserved. ] r ~ t Observations: the vertical elevations in the secondary s'ide are { preserved just below the tcp of the primary steam separator; indeed, the steam dome elevation has no influence on the natural -i { circulation phenomena. l N 1 J - MAIN LOCP PIPING i - The Froude number is preserved, f l ) i 4 { Observations; in the pump suction piping (loop seal) it is impossible to preserve simultaneously the volume, the lowest elevation of the tube and the Froude number. The elevation is very .l t important in small break transients because of the loop seal I l clearing phenomenon. Therefore, two different loop seal j ( geometries will be available: the first one will preserve volume and elevation and the second one will preserve volume and Freude i number. Either of these geometries will be used according to the i phenomena expected for each test run. l 1 J l i i l ) l j 1 11 J i

- The elevation of the nominal water level is preserved ; j - the level swelling phenomenon will be reproduced.' 7 Observations: the level swelling phenomenen can occur in the pressurizer because of the flashing of the liquid here ' contained or cecause of a steam inflow from the primary circuit; this -{ phenomenon has a significant influence on the quality of the fluid discharged.through the pressurizer relief and safety valves. I 1 The preservation of the level swelling has been obtained by i imposing the average void fraction in the SPES pressurizer equal to the ?WR one, for similar thermal-hydraulic conditions; the void n fraction has been calculated acccrding to the Wilson model for .h j bubble rise velocity. .( In the future, however, it will be possible, if necessary, to substitute enis pressurizer vessel with a full height one. d SAFETY INJECTION SYSTEM i 'I t - The accumulator nominal water level is preserved. I Observations: concerning the safety injection pumps (HPIS and I i LFIS), an external circuit will supply the cold legs with the correct flowrate for a given pressure in the primary system. f i i i i + h i t i t 9 12 l 5

!I 1 l 3. DESCRIPTION OF TEST APPARATUS i ? 3.1 SPES location 'i .\\ i. The SPES facility is located at the SIET-Piacenza Laboratories i and is built inside the "Emilia" oil fired power station as shown in l l Fig.3.1/1' (general view). Fig.3.1/2,3 give the plan and elevation h schematic views respectively. i t 5 3.2 SPES general data The schematic flew diagram of SFES is shown in Fig.3.2/1 l Tabs. 3.2/1 + 3.2/3 give the comparisen of tne SFES main characteristics with respect to Ph'R-PUN (the reference plant) and to other safety experimental facilities. i' 3.3 Primary coolant system 'l 4 The primary coolant system (PCE) censists of a simulated reactor I (a pressure vessel centaining an electrical heated rod bundle, the .l "ccre"), primary loep piping, coolant pumps, steam generater U-tube. bundles and a pressurizer. l f l i [ J i t [ t b i 1 5 'h 4 13 .t

. __ ~_ ? Major components of PCS, made of materials listed in Tab.3.3/1,- are described below in detail. Emergency and auxiliary-systems for PCS are decribed in sects. 3.5 and 3.7. f I i 3.3.1 Power channel pressure vessel l l The pressure vessel (PV), heusing the electrically. heated core j and other internals, is shown, in Fig.3.3.1/1. It consists f: - a lower section, the lower plenum (Fig.3.3.1/2) + - a intermediate secticn, the active :ene (Fig.3.3.1/3) - an upper section, the upper plenum and the upper. head (Fig.3.3.1/4)-' i -The PV characteristics are given in Tab.3.3.1/1. i The lower plenum consists of a cylindrical chamber connected to the PV active zone through a tube which holds the nozzles for core coolant inlet and for core bypass. A nozzle is provided at the 4 bottom of the lower plenum to house a sealing device for the outside protruding rod bundle. [~ The PV active zone, having an inside octagonal cross secticn, is built by assembling eleven end flanged sections; electrical insulation and fluid sealing are guaranteed by "klingerity 400" gaskets. + /99I [ r I i ? I f 14 f

t I r Loose flanges, thermally insulated by klingerit rings and sleeves, are used to assembly the end flanded sections to reduce heat f losses from PV wall. -i The upper section is composed of two cylindrical parts flanged one to another (the upper plenum and the upper head); the two { sections are separated by means a drilled plate. Fig.3.3.1/5. The I upper plenum is flanged to FV active zone and holds, in between l i flanges, a proper rod bundle support plate, Fig.3.3.1/6.The upper plenum also holds the three hot leg no::les and the core bypass e upper nq::le. ~! The upper head holds twa no :les for downcome_r / power channel bypass. I The PV geometrical (volumes, cross sectien areas) and physical (masses) data are given in Tab.3.3.1/2. 3.3.2 Power channel rod bundle I The PV core consists of an electrically heated bundle of 97 rods reproducing, in the active zone, the same geometry (rod pitch, rod I i outside diameter and lenght) as the 17x17 PWR-PUN bundle. I The main features of spes core are summarized in Tab.3.3.2/1. The rods Fig.3.3.2/1, are screw fixed at their top to a support i i plate which also acts as a power lug and are kept fastened and i I evenly spaced by suitable grid spacers. Fig.3.3.2/2. The eleven I i spacers are located along the bundle: the top spacer on upper i unheated zone, seven spacers on active zone and three on lower unheated zone. The distances between the spacers are shown in Fig.3.3.2/3 i k i 15 i

~; f f 1 i The axial power profile is uniform for all the rods; radially within the rod array the profile is also uniform anyway local hot spots can be simulated by means of three rods (hot rods) with a c peaking factor of 1.19. f Twenty rods are instrumented, each with 4 thermocouples (K type, t Inconel 600 clad,1 mm CD) induction brazed to the inside rod wall at different axial location as sketched in Fig.3.3,2/3. 1 Tsod bundle volumes, cress flow areas and metal masses are reported -i in Tab.3.3.1/2. a l ? r 'i 1 i e i t i I i g P O 7 3 i i b f i -? r I i i 16 j

f ~ l 3.3.3 Pressurizer-t i The pressurizer, Fig.3.3.3/1, controls primary system pressure during normal and transient plan r,eration and consists of a f cylindrical end flanged vessel equipped with immersion type electrical heaters, spray system, relief and safety valves, no::les for f pressure, temperature and level instrumentation. The pressurizer is cennected to one PCS intact loop (hot leg-2) by means of 1" SCH BO surge line, see 3.3.4, phat will be equipped i ? with a turbine flewmeter: the pretsurizer surge line can also be connected to the PCS broken loop (het leg-3). ? A 1/2" SCE 80 spray line connects the PCS (cold leg-1) to pressurizer tcp (spray nc::le, Tig.3.3.3/2), providing primary coolant for pressure centrel. This line is equipped with an crifice i 2 g device and an air operated valve to measure and to control the- /{lIf spray water flourate. The pressurizer main data are given in Tab.3.3.3/1; surge line and l spray line characteristics are given in Tabs.3.3.5/12,14. e A power operated relief valve (PORV) and two safety valves are provided at the tcp of the pressurizer. i l The POEV and the first safety valve are preperly scaled and designed to reprcduce the operation behaviour of PWR-PUN valves: in t a f particular the cetual final design should assure the required e ] actuation times and the blowdown parameters as already t experimentally checked. The discharge line lay-out will be defined depending on test. I i l r f i b I 17 i r----4 ,-w,,,-_p-,

-~ I l .) l 1 The second safety valve has a set pressure corresponding to 1 -the PCS design pressure and discharges to the atmosphere directly. Six electrical ~ heaters (3.8'KW each one) have been j installed on the external surface of the pressurizer for heat i losses compensation (see fig. 5/6). i 1 1 3.3.4 -- Primary recirculation pumps li Three recirculation pumps (one per loop) drive primary coolant j I into the power channel to remove the core generated heat. These pumps are centrifugal-single stage-vertical shaft type. The rotational speed can be changed in the continuos range +/- 190 % of nominal value (with fluid in two-phase ) i conditions) and the speed variations can be programmed by means of a motor driven regulator. The pumps are designed both for the f t initial transient conditions in normal operation-and as. tool for f operators to influence power channel cooling. i The inside volume is quite similar to the scaled PWB-PUN pump volume and the total inertia is scaled to obtain a' good simulation-( in coast-down transient. } The pump main characteristics are given in Tab. 3.3.4/1 ; I Fig.3.3.4/1 shows the pump cross section assembly. The theoretical pump characteristic head-flowrate, at different speeds, is reported in Fig.3.3.4/2 together with some experimental check points obtained during pump acceptance tests. 4 Rotational speed-flowrate theoretical curves are shown in Fig.3.3.4/3,- they will be experimentally checked later on. a l 18 l I I s 1 l t

The three pumps ar'e connected to common centrali:ed auxiliary ^ systems providing bearing lubrication and seal flushing. The pump seal is a triple mechanical seal comprising of a double seal and back-up tandem seal Fig.3.3.4/4 and Tab.3.3.4/2; it has the actual valuable benefit to guarantee :ero fluid injection into primary circuit. The inner seal (high pressure seal), installed on the pump shaft between the barrier fluid and the primary fluid, is designed to assure zero leakage under whichever normal and transient (i.e. LOCA) conditions.The intermediate seal is designed to leak towards,the cuter seal so to reduce wear and heat generation. The outer seal (low pressure seal) guarantees zero leakage from the sealing circuit to the environment. The sealing system was successfully tested: the seal was found to i perform very well under normal and emergency conditions. 3.3.5 Primary coolant loop piping SPES primary system. Fig.3.2/1, is composed of three equal loops connected in parallel, each one including the following lines: - hot leg, connects the PC outlet to the SG inlet; - loop seal, connects the SG outlet to the RP suction; - cold leg, connects the EP discharge to the downcomer inlet. j j The otner PCS lines (common to all the loops) are: ) - PC downcomer, connects the three cold legs to PC inlet; i - surge line, connects the pressurizer to hot leg 2, 3 ; l I i l 19 i 4 --1
