ne AP600 is the new 600 MWe Westinghouse Pressurizer Water Rextor, currently being developed.

which is cisxw ud by a

• passive

• Emerfency Core Cochng System.

r SPES-2 (Simulatore Per Esperierne di Sicurezza - 5:rnulator for Safety Expenmental Analisys) is the i

new version of the Italian expenmental test fxility SPES. Originally SPES frility was commissioned by ENEA to simulate the Itaisan version of the Westinghouse PWR 312, the PUN (Progetto Unificato Nu:leare) nu:Icar power plant. Now ti.e SPES frihty is being modified to closely represent the AP600 passive safety features and reactor systems. The SPES 2 frihty will be used to perform integral system tests as part of the AP600 desi n ceraficanon.

F 4

In Part A this document provides the scaling basis on which the SPES-2 frihty is based. In order to perform the senhng analysis the geometrac charrtenstics of the reference textor were established. The informauon regarthng the AP600 plant are reponed in Part B. Part C provides the specific SPES-2 scaled design.

SPES 2 SCALING j

I ne scaling enteria used for the original SPES facility have been analyzed in order to venfy their applicability to the SPES-2 design.

i he general entena adopted for SPES stre:

1.

Conservation of thermodynamic concations spressure and temperature).

2.

Power over Volume ratio conservation in each crsmponent.

3.

Power over Mass flow rate conservauon.

4 Fluid transit time prezrvation (if entens I,2 and 3 are observed this is a consequence).

[

5.

Heat flux conservauon in heat transfer components teore and steam Feneratori.

{

t 3

6.

Height preservation in heat tr:insfer components.

Because the reference reactor of SPES was the W312 the following similanties simplify the scahng process-la AP500 vessel is the same of W312 but the core posstion within the pressure vessel has been lowered and the power reduced by 30'i:

2a the AP600 fuel assembhes. shbouFh reduced in power. are similar to the W312 fuel assembhes having the same number of rods assembly and the sarne rod diameter pitch and lenght:

3a the steam pencrator is very similar to the W312 with the esception of the lute bundle (length and pitch of the U-tubesl.

The following decisions with reference to SPES were taken on a cost / benefit bas s:

I the SPES reactor vessel will be used. the core height ws!! be adjusted to match nim A.600 by lb a

mserting tubular pieces at flange elevauons:

2b the steam generators will not be moddied:

)

3b the SPES reactor coolant pumps mili not be modified however their position. their suction and their discharge will be modified to facihtste duphcation of the AP600 cold leg layout, and one RCP will be used per loop:

.:b the steam Fenerator elevation is not modified.

De SPES-2 scahng process has been pertormed assurning these boundary condiuons. For coherence.when possibic. the general and specific entena of SPES have been adopted.

i ne most important point is item 22. smce it allows to unhze the same power channel and heated rod bundle.

The scaling enterion 5 (heat flux conservaoon) defines the scaling ratio for the core power and. on the basis of entenon 2 (power over volume conservation),the volume scale of SPES-2.

A/ 395 =;,

The remaining tractor and safety system components will be defined to mamtsin this volumetne scalmg ratio with the correspondmg component of the reference reactor to the extent procuca!.

Dunng the scaling process the following M%nant rationales were adoprei the elevations between the bottom of the steam generator tube bundle and the honzontal part of the hot leg. core top and cold leg nozzle centerline were preservei the hot and cold leg are dimensioned accordmg to the Froude number, entenon 3 (power over mass flow rate ration and using maumum available distance between vesset steam l

generator and pumps.

2 Tbc two previous statements and the decision to use key custing components. will cause some deviation from the ideal volumetne scahng therefore:

the pressunzer will be located to preserve the bottom elevation (in SPES the nominal level had been maintainedL because it is imponant to maintam the relative elevanon of the pressunzer and the Core Make-up Tank (CMT) water 1:vels:

the pipe between the steam generator and pump will be designed to compensate for the i

volume denvauons of the descening side of the U-tubes. the SG outlet plenum and the RC pump. The hot leg papmF dom 1: stream of the pressunzer surge line will compensate for the volume devtauons of the SG inlet plenum and the ascending part of the SG j

U-tubes.

The following terms are defined for the SPES-2:

Hot leg:

piping from the reactor ussel nozzle (included) to the SG inlet nozzle (mcluded).

Cold leg:

piping from the pump nozzle (not mcluded) to the reactor vessel downcomer nozzle (included).

In parucular the SPES loop piping has been completely changed (hot legs. cold legs and the piping between steam Fenerators and RC pumps).De pump axis has been moved from venical to honzontal to provide a honzontal suction connection and downward discharge.

The reactor vessel will be modified as follows to abtain the proper elevanon between the core and the SGs:

Therefore it has been decided to simulate an annular pornon of the downcomer connected to tubular downcomer below the injection line (and loop piping) nozzle elevation.

The CMT will have the same metal mass to water volume ratio as the AP600 in order to avoid a distorsion in the steam condensation along the tank walls.
