1 Identif ication data of the structure and materials for project processing 1.1 Identif ication data Construction : Assembly and production of the irradiation facility EHN1 GIFpp for CERN Investor: CERN, Route de Meyrin 385, 1217 Meyrin, Switzerland Planner: VF, s.r.o. Žilina Construction location:

CERN, Prevesin, FR SO 887 EHN1 workplace of the beam H4 (beam H4)

1.2 Planner: Company: VF, s.r.o. Registered office: M. R. Štefánika 9, 010 02 Žilina Contact: +421 415 072 411, [email protected] 1.3 Uniform labell ing system A uniform system of labelling of company VF, s.r.o. is used in this report for purposes of documentation labelling. 1.4 Quality assurance Quality assurance, when issuing this document, has been resolved by the means of certified quality assurance system of the company VF, Ltd. under standard ISO 9001:2000. 1.5 Performed surveys Inspection of the construction site was made on October 30th, 2013 to find out actual state. 1.6 Sources used

• order VF 1Z13-3027-NO01, • documentation of actual state of the building and facility provided by investor, • records of negotiations between the planner and investor, • recommended standards, • corporate materials from the archives of VF, • associated documentation of purchased equipment, • quality system documentation

1.7 Brief characterist ic of the building The objective of the investment is complete reconstruction of the testing facility equipment in building 887 part EHN1. The reconstruction includes supplementation of the irradiator by radiation of gamma type GI-02 and 2 pieces of manipulator of radiation shieldings type RA-01 to increase opportunities for testing the equipment on site EHN1 by using beam H4. This is related to increased demands on horizontal dimensions of the irradiation room. Therefore, the irradiation facility will be


page 7/26

rebuilt using concrete blocks to new satisfactory dimensions. New arrangement of the concrete blocks is ensured by the investor.

Mentioned space of the irradiation facility meets all requirements for the location of new technology. Control of new devices will run out of these premises via cables to the service area where the power and control circuit of devices are located. 1.8 Reason of the change The new facility will expand options for testing detection equipment on the workplace EHN1. 1.9 Description of the current state Workplace EHN1 is for testing of measuring equipment needed for analysis using beam H4. Sources of IR have not been used for testing on this workplace so far. 1.10 Proposed change New panoramic gamma irradiator GI-02 will be used to expand opportunities for testing as well as 2 pieces of manipulator of radiation shielding RA-01 which will be located in the irradiation facility of object 887 on workplace EHN1. To achieve desired shape of the gamma field, the gamma irradiator has got lead shielding in shape of a lens inserted in the front collimator. Also new heavy current and light current wiring will be adjusted to the new arrangement. 1.11 Consideration of the customer Consideration of the customer is necessary for successful realization of the supply and assembly. The consideration consists of the following:

1. confirmation of the length of all cables, 2. assignment of identification numbers of all cables, 3. WS16 cable assembly, because VF does not know the route of the cable as well as its length, 4. WS17 cable assembly and connection, because VF does not know the route of the cable as

well as its length and the connecting terminals, because VF does not know the route of the cable as well as its length and the connecting terminals,

5. WS18 cable assembly and connection, because VF does not know the route of the cable as well as its length and the connecting terminals,

6. determining the place of assembly of the OP-01 console, 7. moveable platform readiness for the equipment assembly, 8. supply and assembly of the cable power carrier, 9. ensuring availability of a crane with lifting capacity of at least 10,000 kg on workplace EHN1 10. access to the workplace 11. storage space 12. power for working tools 13. sanitary facility for workers 14. UPS is only an option

Overview of the technology and orientation of the building 887 on workplace EHN1 is clear from the following figure. (Jura – north-west direction, Saléve – south-east direction, concrete - shielding, area 4 - PPE entrance, area 5 - PPX emergency exit, S - location of facilities GI-02 and RA-01)

Figure 1 Orientation on workplace EHN1 2.2 Power supply The device is powered from the existing distributor on CERN. Wiring and routes are provided by the customer. Estimated total power of the installed equipment is about 3000W, the required voltage is 1× 230V, 50Hz system TN-S (L+N+PE). 3 Dismantling Original equipment of the BA irradiator will be dismantled within this project. Description and procedure is subject of a separate technical report. 4 Technical data of the main components 4.1 GI-02 irradiator GI-02 is a device designed as an IR source for radiation of testing devices. GI-02 is made up of the following components: base of the irradiator, body, basic shielding, additional shielding, collimator front - primary, collimator rear - secondary and associating cabinet. GI-02 frame consists of the supporting frame with four adjustable legs which set the GI-02 to its vertical position and fix it on the base so that the axis of the bundle is in the desired height above the floor (1800 mm). See figure arch. No. VF 2Z13-1720-CT1A02 and figure No. 2 which shows a B-B section. The body consists of construction blocks with a steel corset which are filled with lead with necessary

page 10/26

The total thickness of the shielding is 200 mm. Additional shielding is deposited on an additional shielding beam which is fixed on the basis of the irradiator GI-02 item 1. Additional shielding (items 2 to 6) provides reduction of the dose rate on the surface of GI-02 to the value of ≤2,5mikroGy/h. The collimator is the part of the irradiator that directs photon flux into one direction and a desired beam angle which is called collimation angle. GI-02 contains 2 collimators - front and rear. The front (primary) collimator based gamma radiation in direction of beam H4 leads to the downstream area (dwstr). The rear (secondary) collimator based gamma radiation upstream the beam H4 leads to the upstream area (upstr). There are two associating cabinets located on GI-02 which combine signals from individual components into multi-core cables. These cables are coupled in the control box RACK RS-01. The control box is a separate part of GI-02 which is associated with the GI-02 cables. These are cables WS01 and WS15 which are flexible and pass through the cable carrier between the movable platform and cable terminations with the cable channels. Flexible cable carrier has minimum internal dimensions to store the cables, height 60 mm, width 200 mm and will store 15 pieces of cables with a diameter of 16 mm. Flexible cable carrier is included within a supply from CERN. VF assumes that the carrier is mounted on the platform and will be part of it. The control electronics of RS-01 is located in the RACK cabinet close to GI-02 at the service area. Description of the cabinet RS-01 can be found in chapter 4.2.2. 4.2 Principle of operation The principle of operation of the irradiator is based on ejecting of the radiation source of desired activity from the bottom - safe position via transport pipeline to working position (to the space of collimators axis). The irradiator is ejected to the working position for the period that is set by the operator of the device. After the irradiation has finished it automatically moves to the safe position. After the source has been allocated in a safe position, this state is sensed by sensors, information is transmitted to the higher-level system which, after submitting a request, allows the operator to enter ambient of the irradiator (radiation facility). In case of recorded breach of terms of irradiator ejection, the irradiator is immediately dropped into its safe position. In case of interruption of the power supply in any stage of GI-02 operation, the gravity will move the irradiator to its safe position which ensures high level of security. The irradiator is equipped with a status indicator GI-02 in line with safety requirements. Indication lights flash green light, when GI-02 is in its safe position without motion. Yellow colour flashes in case the irradiator of GI-02 is moving or is not in its safe position. The entire visual system is completed by alarm, an acoustic signal that indicates each change of state of the whole technology. 4.2.1 Main technical data Gamma irradiator GI-02

4.2.2 Control box RS-01

Control box RS-01 consists of steel cabinet RACK 600×800×2000 mm (w × d × h) which is located on the service surface close to the irradiation facility, for more information see the Layout drawing.

The cabinet contains power supplies and communication interface for the higher-level system along with control circuits needed for operation of the irradiator´s manipulator and both RA-01 attenuators. RS-01 is thus composed of three parts. It´s a common supply part, part of the circuits for GI-02 and part of the circuits for two pieces of RA-01. The distributor contains all necessary inputs, outputs and signalling needed for safe manipulation with the irradiator and aperture manipulators for the front and rear bundle. On the RACK box (RS-01), the following states of the device will be displayed using 10 pcs of LEDs:

The following signals are concerned: 1. ACCES CONTROL VETO 1 2. ACCES CONTROL VETO 2 3. EXTERNAL VETO 1 4. EXTERNAL VETO 2 5. INTERNAL VETO - RUN UPS 6. USER VETO 1 7. USER VETO 2

4.3 Attenuator RA-01 Manipulator of irradiation shieldings of RA-01 (Radiation Attenuator, hereafter referred to as RA-01) is an electromechanical device used to manipulate the shieldings and set up DR in collaboration with the irradiator GI-02. Shieldings move in front of the collimator GI-02 and according to the total thickness various attenuation bundle occurs which changes DR.

RA-01 contains three frames (A, B, C) for shielding segments in the block and three layers of shielding blocks (1,2,3). Blocks are moved in front of the collimator by the stepping engines with acceleration and deceleration. Individual blocks are connected to counterweight by double-row roller chain. The chain is driven by a gear wheel. The engine speed is reported by the sensor mounted directly on the motor shaft (IRC). Block location is sensed by an absolute position sensor (B1, B2, B3). End position of the blocks is reported by end limit switches (KS1, KS2, KS3). End position of the counterweights is reported by end limit sensors of counterweights (KS4, KS5, KS6). In normal operation the end limit switches are not activated. Counterweights balance the system of attenuating apertures.

Control circuits in RS-01 ensure communication with the higher-level system, necessary supply voltages, control of all engines, etc. The main switch for RS-01 and GI-02 as well as power-on indicator is located on RS-01.

5 SW system of the RA-01 communication RA-01 device will communicate with the control system CERN - GIF (GCS) over Ethernet (peer to peer) by cable WS19. Communication protocol VF will be used. The protocol is described in the document arch. No. VF 2Z13-1720-BN01. 6 Security system The purpose of the security system is to prevent unintentional, accidental irradiation of personnel when working in irradiation facilities. The irradiator provides:

• acoustic warning • visual warning

All other security functions are provided by the control system CERN access control system CERN which shall guarantee safe access to the specif ic area of the irradiation faci l ity (zone). The zone represents the area enclosed by a fence or a wall with several access nodes - (doors). In our case, the zone means irradiation bunker with concrete wall 1.6 m thick and with two doors (one large, one small) and one emergency exit. The zone has several states - modes. Two most important modes are OPEN and CLOSED. There are still some more modes (e.g. PATROL), however these behave like OPEN mode. They only constrain movement of persons who may enter the bunker or specify who needs to use special key.

OPEN mode: Access to the bunker is possible. This is the reason why access control system (ACS) must guarantee that the bundle of particles (in our area H4) shall not reach bunker, i.e. will be interrupted by shielding or turned off, and irradiation facility GI-02 can not start irradiation. CLOSED mode: Nobody may enter the bunker. In this mode the bundle of particles may be loaded to the bunker and also the irradiation device GI-02 can be launched. Whenever the bunker is accessible (i.e. the zone is in the open mode) the access control system will send a PROHIBITION signal (VETO) to the irradiator and this device must send feedback as a response on this PROHIBITION signal which demonstrates that the PROHIBITION signal has been accepted and applied. In this case, the driving mechanism of the movement of gamma rays source (137Cs) will be separated from the power supply. The PROHIBITION signal is not sent out of the access control system and the irradiation device may be launched ONLY in the CLOSED mode.

6.1.1 Acoustic warning Another technical measure is an acoustic warning before irradiator ejection, which indicates

the irradiator ejection. The acoustic alert is generated by GI-02. The sound will be running 5 seconds prior to the irradiator movement, throughout the duration of the irradiator movement and even two seconds after the irradiator has stopped in the collimator.

6.1.2 Visual warning

Visual warning is located in the irradiation facility on the device GI-02. It visually informs the operator about the current state of the technological device. Importance of the colours of the visual warning is following: green - irradiator down, yellow - irradiator in motion, red - irradiator in the collimator. 6.1.3 Basic condit ions of the security system 6.1.3.1 Condit ions for unlocking the electr ic door lock - enable entry

• GI-02 is in the basic position. • while the irradiator is not exposed in the collimator • while the VETO signal is on • while green light is on on GI-02

6.1.3.2 Condit ions for exposit ion of the irradiator The relationship between below mentioned conditions is AND (while) • the irradiator is in the nest (in the safe position) • signal VETO 1 is not exposed • signal VETO 2 is not exposed • signal EXT VETO 1 is not exposed • signal EXT VETO 2 is not exposed • signal UPS-BAT is not exposed • button EMS has not been pressed • button STOP on the console has not been pressed • the set time of irradiation has not expired • signal US VETO 1 is not exposed • signal US VETO 2 is not exposed • signal US VETO 3 is not exposed • signal US VETO 4 is not exposed 6.1.3.3 Condit ions for safe storing of the irradiator The relationship between below mentioned conditions is OR (at least one)

• signal VETO 1 is exposed • signal VETO 2 is exposed • Signal EXT VETO 1 is exposed • Signal EXT VETO 2 is exposed • signal UPS-BAT is exposed • Button EMS has been pressed


page 24/26

6.1.3.4 Condit ions for correct secretion of the irradiator

• Button STOP on the console was pressed • The set time of irradiation has expired • Signal US VETO 1 is exposed • Signal US VETO 2 is exposed • Signal US VETO 3 is exposed • Signal US VETO 4 is exposed • Loss of internal communication occurred in GI-02

6.1.4 Signall ing system Signalling is placed in the irradiation facility directly on the irradiator GI-02:

- Light (green, yellow and red) - Acoustic

The cabling shall be maintained in cable trays and cable canals. The cables between the moveable platform and the fixed cable channel held in the membered power carrier. The power carrier is not part of the supply. VF assumes that the carrier is mounted on the platform and will be part of it. Existing transfers will be used between the irradiation facility, service area on the spot height 0.0 m and cable channels on the floor +3.6 m. Cabling will be placed under the cable list VF 2Z13-1720-CT1B02. Principles of separation by voltage level need to be adhered to when laying down the cables. The cables will be labelled under the cable list. The cable labels will be placed on both ends of the appropriate cable.

Marking of all components is specified in the technological scheme, layouts and in the list of machinery and equipment. 10 EMC requirements All electrical elements must meet electromagnetic compatibility requirements, also principles stated in the BK as well as Concept of the lightning protection of the SKR systems must be adhered to. The voltages of noise voltage levels are stated in STN EN 50 082-2. It is necessary to adhere to these main principles to ensure, that the noise voltage levels do not exceed determined values:

• separate cables by voltage level • low voltage cables may be stored only on their own grids (distance from the other grids 0.2

m), cables that do not meet these principles must be placed in canals. 11 Characteristic of operation The whole system is designed for continuous operation. Maintenance will be carried out according to the manuals of supplied devices. 12 Characteristic of environment New equipment affects the environment of the areas of installation and therefore the existing environment has changed after installation of the device. Characteristic of the technology remains the same after execution of the construction. Protocol on determination of externalities has not been delivered. 13 License terms Reproduction, transfer, distribution or storage of parts or all of the content of this document in any form without prior written approval of the company VF is prohibited.
