Design and construction The design and construction of the equipment shall conform to the best current engineering practice and in agreement with IEC Std. The essence of design shall be simplicity and reliability in order to give long continuous service with minimum maintenance requirements. As far as possible, the Industrial Supplier shall design and manufacture the components included in the present specifications in line with his own standard manufacturing. Modularity shall be used to the maximum extent possible so as to minimize the time required for maintenance and repair. All components and cables shall be able to support mechanical forces during shipment, and electromagnetic forces occurring during normal operation and fault conditions. 4.2.2. Redundancy and safety factors Thyristor converters shall be designed in agreement with IEC 60146 Standard. In order to ensure a good reliability for the PS systems, suitable safety factors shall be adopted at least not lower than the maximum ones normally used in industrial practice. The Industrial Supplier shall demonstrate that the values are appropriate for the present procurement. In particular, the following values shall be taken into accounts for thyristors/diodes: Voltage safety factor ( defined as max repetitive peak forward blocking voltage/secondary transformer no-load RMS voltage) : ≥3,5 The maximum junction temperature on normal operation shall be at least less than the maximum junction temperature recommended in thyristor data sheet Thyristor junction temperature after a converter fault: for this purpose it shall be assumed that the most severe fault occurs after the thyristor has reached the maximum junction temperature in normal operation. Under this assumption, in principle, the thyristor junction shall remain in the limits shown in the data sheet. The Industrial Supplier can propose during the DDP different values depending on specific information provided by the thyristor’s Manufacturer. Current sharing factor in case of paralleled components : ≥ 1,2 (the Industrial Supplier shall take any provision to reduce current sharing at minimum level and shall demonstrate it during DDP. This value shall be used to select the proper thyristor component and shall be, in any case not less than 1,2) In case of redundant components, the failure of one component shall result in the exclusion/by-passing of that component without affecting the operation of the overall device. An alarm shall be generated to warn about the failure. The CB units are extremely important to save the investments and for the continuous operation of JT-60SA. The reliability of CBs are therefore of paramount importance and the design of the equipment covered by this specification shall therefore consider the reliability as one of the prime aims. 4.2.3. Availability The unavailability, only depending on internal faults (i.e. faults occurred on the load or induced by the load or by the AC network, faults due by unproper use of the apparatus and maintenance time are not included), of each power supply shall not exceed limits defined in the following criticality Matrix. The acceptable cases are called “A” The unacceptable cases are called “U” UTFUS Italian National Agency for New Technologies, Energy and Sustainable Economic Development Fusion EURATOMENEA Association Procurement Technical Specifications for the Agreement Of Collaboration F4E-ENEA for the Joint Implementation of the Procurement Arrangement for the Poloidal Fields and Fast Plasma Position Control Coils Power Supplies for the Satellite Tokamak Programme ENEA ID: SPT-JT60-PS-01 Page: 20/78 JT-60SA DMS: BA_D_2276VA Rev. 2 26 Jan 2012 Breakdown means the unavailability of the function or the equipment.

The availability ratio is = (150 x 10 – 12.4) / (150 x 10) = 99,17 % All the equipments have to be designed to achieve such an availability ratio taking into account the optimization of the MTTR (mean time to repair) and MTBF (mean time between failure). 4.2.4.Transmission and insulation of signals The transmission of the signals between components placed inside high voltage areas and components/equipment placed in low voltage (accessible) areas shall be as much as possible via optic fibres, which also assure the insulation of the signals. If the signal transmission via cable is selected, the signals shall be double isolated for the relevant test voltage applicable to the particular HV component, in such a way that failure of one insulating layer does not endanger personnel and/or equipment at the low voltage side. Alternatively a screen may be provided between high voltage circuits and low voltage parts. The screen will in general be connected to the local ground system of the supply. The screen shall be able to withstand the relevant fault current for the time required to clear the fault. Different arrangements shall be subjected to the approval by the Customer during the Detailed design Phase (DDP).

Combustible materials Material that would support combustion must be LSOHFR (Low Smoke Zero Halogen Fire Retardant). In particular for cables and optical fibres refer to Section 4.2.17. 4.2.6. Cleaning and painting Before receiving any protective coating or paint, all parts of the equipment shall be cleaned to remove all corrosion and foreign materials. All interior and exterior surfaces shall receive a suitable inhibitive primer treatment and two coats of finish paint. The board colours will be agreed during the DDP with the Customer. 4.2.7. Audible noise This section refers to the audible noise outside the cubicles ( taking closed the cubicle doors) in normal operating and stationary conditions. All equipment shall operate without undue vibration and with the lowest possible audible noise to avoid causing any harmful effect. In particular the daily average noise value (calculated as an average over 8 hours and expressed i in dB(A))must not exceed 85dB(A),when measured at 2 m. distance and using an instrument according to IEC 61672 . During the switching phase, peak noise and vibrations shall be reduced under a threshold to be defined during DDP. 4.2.8. Use of oil PCB (polychlorinated biphenyl) and PCT (polychlorinated triphenyl) component. Large oil filled equipment shall not be installed indoor . type materials shall not be used in any 4.2.9. Use of ISO metric threads All nuts, bolts, studs, washers etc. shall be of standard ISO metric sizes. Other sizes may be permitted only after approval by the Customer. 4.2.10. Anti-condensation devices All items of electrical equipment which are liable to suffer from internal condensation shall be fitted with proper device which will prevent condensation in worst ambient conditions (ref Section .11) The operation of these devices shall be monitored and an alarm rose in case of failure. Local visible indication of failure shall also be provided. These devices shall be energised separately from any other equipment in the enclosure/cabinet. 4.2.11.

If the boards will be provided with windows, the glass used shall be of shatterproof safety type. 4.2.13. Grounding All equipment enclosures, screens and metallic parts (wherever requested by IEC standards and/or local regulations) shall be grounded (ref. Section 4.6.5). Each enclosure shall be provided with suitable bonding leads to connect together all the part of the enclosures (e.g. doors) and all items inside the enclosure requiring grounding. All the ground conductors shall be made of copper and shall be sized to carry the fault current without voltage rises dangerous for the human safety. All power ground leads shall be sized according to the IEC standards and/or local regulations applicable to the components/sub-systems of the supply. All the grounding connections shall be clearly pointed out and easily accessible. 4.2.14. Resistors The technical requirements for power resistors are given as follows: - Tolerance of the resistance with respect to the nominal value shall be according to the relevant IEC standard. The range of ambient temperature is given in Sections.11. - Resistors shall keep their resistance value within the specified limits during all their service life. The resistors may be subjected to occasional current overloads that shall be defined during the DDP. A conservative number of maximum overloads shall also be considered in determining the service life. - Industrial Supplier shall provide that the maximum stray inductance remains below values not affecting the performance of the equipment where the resistor is implemented. 4.2.15. Reactors To comply with the technical PS requirements (Sections 4.4 and 4.5), interphase/circulating reactors between two parallel bridge or/and back to back connections are needed. The scope of these reactors is: - Parallel connection: due to the not equal instantaneous outputs of each rectifier , an interphase reactor is used to support the difference in instantaneous rectifier output voltages and allow each rectifier to operate independently. - Back to back connection: an interphase reactor is necessary: to take the circulating current within 10% of the DC nominal current (I DC,nominal ), to reduce the circulating current ripple, that might be large for the transformers with the phase shifting of 30 degrees, within a limit acceptable for a safe and reliable operation of the PS. For all these reasons it seems to be better to use a saturable reactor type to provide the two necessary inductance values in both full and circulating current conditions . In any case the Industrial Supplier could evaluate alternative solutions, that shall be quoted in the offer separately, and he shall prove their convenience during the DDP of the Contract. Attention must be taken that the reactors are situated sufficiently far away from neighbouring metallic parts to ensure that these aren’t heated excessively by eddy currents. The tolerance of the inductance with respect to the nominal value at 50 Hz of each reactor shall be according to the relevant IEC standard. In particular, the inductance values of the two branches of the interphase reactance can differ each other inside the range: 0 / +20% (IEC 60076-6 “smoothing reactors”).

The determination of the inductance value shall take into account the expected conditions of installation and the presence of nearby metallic structures. All related design details shall be discussed during the DDP. 4.2.16. Capacitors Power capacitors may be used in various parts of the supply: filters, snubber circuits, capacitor banks... The nominal values of capacitance for each capacitor unit shall be referred at a frequency or typical frequencies range of the specific applications. The main characteristics (including inductance and resistance) of the capacitors shall be selected by the Industrial Supplier to ensure a safe and reliable operation of the PS. The tolerance of the capacitance with respect to the nominal value shall be according to the relevant IEC standard. 4.2.17. Cables and fibres optics All used cables shall be selected, sized and laid according to applicable IEC standards, in particular IEC60502. All power, measurement, control and auxiliary cables shall be made of copper. Cable and fibre optics insulating material shall be LSOHFR (Low Smoke Zero Halogen Fire Retardant, ref IEC60332-1, -2 -3).

Analogue signals shall be routed separately from digital signals, using different cables. To reduce interference on control, protection and monitoring signals, twisted pair cables shall be used and located inside proper cable trays. During the DDP, the Industrial Supplier shall demonstrate that the proposed cabling and wiring systems comply with EMI/EMC IEC standards. Each multi-pair or multicore cable shall allow for at least 20% spare capacity. All spare cores shall be terminated. The design of the fibre optic transmission system shall allow for at least 10% spare fibre optic cable capacity. Within cubicles/panels, all cables shall be clearly identified with a label of an approved type and this label shall be clearly visible from within the cubicle/panel. Labelling criteria will be defined during the DDP. 4.2.18. Demineralised water cooling system Demineralised water cooling system for aluminium components will be made available by JAEA (ref.

CBs can be operated in the following cases: 1. automatically, by an internal Break-over-diode (BOD) in case of overvoltages across DC busbars and to ground, the non-linear resistance Rnl will protect the PS of the overvoltages before the static switch (BOD) intervention 2. by the thyristor converter control system to protect the converter itself ( for example in case of AC voltage missing, internal fault, max DC current,…); 3. by an external command by the JT-60SA SCSDAS, GPS or QDC (for example in case of Quench Protection Circuit operation). The proposed reference basic scheme and operation sequence are described in Fig. 4.2.22-1 and Fig. 4.2.22-2. In principle no resistance is foreseen in series with the CB. This is to make easier current commutation from the converter into CB. The Industrial Supplier shall check the situation during the DDP and propose motivated modifications on the basis of his experience and his calculations. Without any resistance in series with the CB, the time constant of the load current decay will result too high and the consequent I2t will overcome the CB capability. As a consequence, in case of CB operation also Quench Protection Circuit must be operated ( Reference 3). In the proposed reference scheme of Fig. 4.2.22-2, non linear resistances (Rnl) are included in order to smooth over voltages across the converter before crowbar operation. The Industrial Supplier shall propose alternative schemes also analysing if Rnl resistors are strictly needed depending on the thyristor converter design. A final decision will be taken during the DDP.

Disconnectors Each PS must be disconnected from DC side by remotely operated no-load disconnecting switches. AC grounding manually operated disconnectors on the AC input from the secondary sides of the transformers are needed In both cases, a proper set of key inter-locks shall be provided to avoid any improper operation. All DC disconnectors shall be operated in both Local/Remote mode (ref. Section 4.7). All disconnectors shall be able to withstand the most severe overvoltage/overcurrent. 4.2.24.

Expected typical currents are shown in Figure 4.4.3-2 (ref. to PID section 1.2) to inform the Industrial Supplier regarding the control requirements for the PSs. With reference to Figures 4.1.1-1, 4.1.1-3 and 4.4.1-1, the typical pulse includes the following steps (TBD during DDP): I. Between two plasma shots (t<<-40s) each PFC PS is in a steady state shut-down condition, this means: a) H-MG at nominal voltage and nominal stand-by speed b) all AC HV circuit breakers/disconnectors open (if requested) c) all DC disconnectors open (if requested) d) all thyristor converter blocked e) no reference signals from PS SC f) water cooling system in nominal operating conditions and under monitoring UTFUS Italian National Agency for New Technologies, Energy and Sustainable Economic Development g) h) i) j) Fusion EURATOMENEA Association Procurement Technical Specifications for the Agreement Of Collaboration F4E-ENEA for the Joint Implementation of the Procurement Arrangement for the Poloidal Fields and Fast Plasma Position Control Coils Power Supplies for the Satellite Tokamak Programme ENEA ID: SPT-JT60-PS-01 Page: 36/78 JT-60SA DMS: BA_D_2276VA Rev. 2 26 Jan 2012 auxiliaries voltages at nominal values and under monitoring compressed air (if present) at nominal value and under monitoring safety interlock signals ok and under monitoring no alarm/fault signals and situation under monitoring II.

Starting a) b) c) premagnetization (in the standard scenario, t=-40s) PS SC: unblocks CS1, CS2, CS3 and CS4 thyristor convertors sends the proper load voltage/current reference signals to all thyristor convertors monitors the sequence status and alarm/faults for each PS IV. At t=-10s : Base PS converters EF1 and EF6 are unblocked (in the standard scenario) and Booster PSs are also activated simultaneously. V. At t=0s (typically), a voltage step (typically 5kV) across each coil is needed to generated a di/dt load current to induce plasma current breakdown in the JT-60SA vacuum chamber. As this voltage value exceeds PS capability (ref. Table4.4.2-1) , it shall be generated by inserting in the circuit: a. proper resistors by fast Switching Network Units (SNU) for CS1, CS2, CS3, CS4 PSs b. Booster Units for EF1 and EF6 PSs , able to provided the requested voltage. Both SNUs and Booster units are by-passed as soon as the requested voltage across the coil comes again inside the PS capability limit and, in any case, for SNUs, before load current zero cross. Both SNUs and Boosters are not included in the present procurement. VI. Regulating the PS current following the reference signal during the plasma shot VII. Ending of the plasma shot (typically from t = +130s),. VIII. Decreasing the PS current to zero in about 40s. IX. PS SC set again the system in a steady state condition (point I, above) It has also to be underlined that Quench Protection Circuits (QPCs), not included in the present procurement, are by-passed during a normal pulse. They are operated to protect each superconducting coil in case of internal quench ( when the coil is not longer superconducting and becomes normal conducting). QPCs includes in the circuit an additional resistance to generate a fast ramp down of the load current. At the nominal current, the QPCs resistance generate a voltage drop of about 5kV. In any case, together with QPC operation the converter current ramp-down and the crowbar operation shall be always required.

This has the double scope to reduce stray capacitance and to prevent any contact between the windings in case of insulation failure. For this reason the screen has to be grounded; transformer case shall be protected against possible oil overpressure with suitable apparatus to prevent any risk for the operators and the other nearby apparatus; the Industrial Supplier shall demonstrate it during DDP; HV and LV transformer connections shall be protected with an IP52DH (Sections 4.2.12) enclosure.

FPPC coils power supplies Two separate PS have to be procured separately for FPPC upper and lower coils. These PS have the function of controlling vertical and horizontal position of the plasma against small plasma perturbation or a minor disruption.
