SIET D35unOct Rev. Ch00k Pago of l Ses. Reattori IP.novativi 001578T92 A 39 l 51 l ATTACEMENT 1 - Plate wall thermocouples installation A1.1. Introduction. Each tuermocouple is brazed on a AISI 304L plate. In fig.A1.1 are reported the geometrical dimension of the plate wall thermocouples. A1.2. Plate wall thermocouples installation A1.2.1 Thermocouple handling The thermocouple is contained in AISI 316 sheet. The minimum allowable radius of curvature is 10 times the thermocouple sheet diameter. A1.2.2 Installation of plate wall thermocouples Install the plate wall thermocouple to the measurement objective by means of spot welding. In order to secure quall:y welding, pay attention to these important factors:
-cleaning of the area to be in contact with the plate wall thermocouple
-proper output of a spot welder
-and also proper electrode contact pressure to be applied to a measurement objective.
Outline of the plate wall thermocuple installation: 1)Take the plate wall thermocouple out from the container, and streighten itself.
- 2) Apply necessary treatements to the contact area of a measurement objective, clean the part of thermocouple plate that has to be in contact with the application surface see fig.A1.1
- 3) Set the plate thermocouple in the position of installation and fix the sheet.
- 4) Spot veld the plate of the thermocouple.
Detailed instruction follow.

t SIET Dscuncnt Rev. Chock 'Pcgo of Ses. Reattori Innovativi 001578T92 =A 40 51 A1.2.2.1- Surface treatments
- 1) Remove rust, dust, grease and other foreign matters from the contact area of a measurement objective ,
- 2) Use # 100 or thereabout sandpaper to remove rust. Then smooth ,
the area using # 320 or thereabout sandpaper. < If the area is not much rough, smoothing with # 320 sandpaper may be enough.
- 3) Thoroughly remove stain and grease .from the. area using a solution such as Freon or acetone. The thermocouple plate has- a sand blasted and thus clean contact surface..If need be, use freon or acetone to remove grease.
- 4) After removal of grease from the thermocouple and a measurement objective, avoid touching their contact area.
A1.2.2.3 Plate thermocouple welding The plate thermocouple must be positioned on the measurement objective surface as in fig.A1.1-
- 1) A spot welder of 20 watts /second capacity permits welding ' of the plate thermocouple to most materials.
Before welding the plate thermocouple , perform trial welding so that the output and contact pressure of a welder can- be adjusted to optimum condition. Set the output of a welder at 10 to 12 watts /second, and electrode pressure at 0.5 to 1.0 kgf.. The optimum diameter of the electrode tip is 0.8 mm v thereabouts Recommer.dations :
-The myuired strenght of a welded joint to be made. is such that when a spot welded sta:tnless steel plate, about 0.1 mm thick is forcibly removed from taa joint -with a pair of pincers, weld spot- _
stay on the mating material, thus ' making holes on the plate removed. If -holes are- not made, it is 'the indication. of insuf ficient welding st::ength
-2)In the first place, parform tentative spot welding at two spot in the central pare n? the flange.
After-that, perrsrm pot welding towards the ends of the flange Reccomendations :-
-Take care to keep the tip of-an electrode'inside the edges of the flange.
-Take care to keep equal intervals of spots and avoid overlapped-spots which may cause a spark and reduce the weld strenght.
-Absolutely avoid the tip of an electrode .on parts other than flange.
-If electric ' spark occurs, the cause- may be oxidation, deformation, or poor treatement of the surface of an electrode.
To. avoid a spark,-take care the following measures: a) Polish -the tip of an electrode with sandpaper (# 800 or
. thereabouts) a e

SIET D3 Gum:nt Rcv. Ch00k P0g3 of Scs. ROOttori Innovativi 001578T92 A 41 51 l b) Properly adjuste the electrode pressure. c) Clean the contact area of a measurement objective as well as the flange of the thermocot.ple. A1.2.2.4 Installation of internal plate wall thermocouples of the headers The plate wall ther=ocouples that have to be installed on to the internal wall of the upper header will be supplied with a mounted seal device (thermolock type). These thermocouple have to be handled and installed as described in the following stages:
- 1) Insert the thermocouple in to the header through one threaded hole of the 2" nozzle cover cap. The thermolock in this to remains outside the header (fig.A1.2 [a])
- 2) Set the thermocouples in the position of installation, and fix the sheet near to the position (fig. A1.2 (b)
- 3) Take care to leave a certain lenght of the termocouples sheet free (formed as in fig.A1.2 (b)) inside the header before locking the the cover cup and the thermolock 1

Introduction The capsulate strain gages that have to be installed are classified into two kinds, G7 and G8 according to sheat materials adopted For the G7 the entire sheat is made of SUS 316 For the G8 the entire sheat is made of Inconel 600 A3.2 Strain gages installation A3.2.1 MI cable installation Take care not to bend the strain element when stretching the MI cable. If there is the need for bending the MI cable, start bending over 5 mm off from the connection. The radius of curvature should be larger than 4 mm ( A3.1) . Reccomandation: -Avoid a force on the connection of the strain gage and MI cable when stret:hing or bending the MI cable. -If the MI cable needs to be bent near the strain gage (at a distance shorter than 100 mm from the connection of ths3 strain gage and MI cable), do it before installation of the strain gage, and easy bending will be allowed, it will also prevent damage to the strain gage (fig.2). If the MI cable is to be bent nearer the connection, fix the cable in advance nearby the strain gage. A3.2.2 Strain gage installation Install the strain gage to the measurement objective by means of spot welding. In order to secure quality welding, pay attention to these important factors: -cleaning of the area to be in contact with the strain gage -proper output of a spot welder -and also proper electrode contact pressure to be applied to a measuroment objective.
SIET DocunOnt R0v. Ch03k Pago of Sts. ROctteri Innsv3 tivi 001578T92 A 47 51 Outline of strain gage installation: 1)Take the strain gage out from the container, and streighten the MI cable.
- 2) Apply necessary treatements to the contact area of a measurement objective. Clean the flange of the strain gage .
- 3) Set the strain gage in the position of installation and fix the MI cable.
- 4) Spot weld the flange of the strain gage.
Detailed instruction follow. A3.2.2.1 Surface treatments
- 1) Remove rust, dust, grease and other foreign matters from the ,
contact area of a measurement objective
- 2) Use # 100 or thereabout sandpaper to remove rust. Then smooth the area using # 320 or thereabout sandpaper.
If the area is not much rough, smoothing with # 320 sandpaper may be enough. 1
- 3) Thoroughly remove stain and grense from the area 3) Thorou- 3 solution such as Freon or acetone. The strain gage has a sand l blasted and thus clean contact surface. If need be, use freon or ,
acetone to remove grease. i
- 4) After removal of grease from the strain gage and a measurement objective, avoid touching their contact area.
A3.2.2.2 MI cable fixing l
- 1) During installation, prevent the strain gage from going under the weight of the MI cable, thereby avoidig tension -or torsion which can damage the strain gage. To serve this purpose, tie the MI cable with a wire or fasten with a clamp via a rubber cushion. ;
Do this after setting the strain gage in the position vf the installation.
- 2) Clamp the MI cable then fix it with a thin metal strip 4 to 5 mm in vidth. (the attached accessory metal strip is approximately 0.08 mm thick stainless steel fig.3)
Reccomandations Do not fail to fix the MI cable preceding to installation of the strain gage.
4 SIET Documtnt Rov. Chtek Ptgo of Ses. Reattori Innovativi 001578T92 A 48 51 A3.2.2.3 Strain gage welding
- 1) A spot welder of 20 watts /second capacity permits welding of the strain gage to most materials.
Before welding the strain gage , perform trial welding so that the output and contact pressure of a welder can be adjusted to optimum condition. Set the output of a welder at 10 to 12 watts /second, and electrode pressure at 0.5 to 1.0 kgf. The optimum diameter of the electrode tip is 0.8 mm or thereabouts (fig.4) Recommendations : -The required strenght of a welded joint to be made is such that when a spot welded stainless steel plate, about 0.1 mm thick is forcibly removed from the joint with a pair of pincers, weld spot stay on the mating material, thus making holes on the plate removed. If holes are not made, it is the indication of insuffic:.ent welding strength 2)In the first place, perform tentative spot welding at two spot in the central part of the flange see (a) in fig.5. After that, perform spot welding towards the ends of the flange in the order of (b) to (e) as shown in fig.5. Recommendations : -Take care to keep the tip of an electrode inside the edges of the flange. -Take care to keep equal intervals of spots and avoid overlapped spots which may cause a spark and reduce the weld strenght. -Absolutely avoid the tip of an electrode on parts other than flange. -If electric spark occurs, the cause may be oxidation, deformation, or poor treatement of the surface of an electrode. To avoid a spark, take care the following measures: a) Polish the tip of an electrode with sandpaper (# 800 or thereabouts) b) Properly adjusta the electrode pressure. c) Clean the contact area of a measurement objective as well as the flange of the stra.n gage. A3.2.2.4 Strain gage welding on a curved surface. Bend the strain gage in advance by pressing against a pipe or the like which has the same curvature as a measurement objective. When pressure is removed, the strain gage curvature will be lost more or less. To avoid it, press the strain gage during welding with a rubber sheet or the like against the curved surface of a measurement objective (fig.6).

Software The software used to perform the data acquisition process is based on VAX/VMS (DEC) operative system and on VAX/RDB (DEC) relational data base. All applied software use the properties and the libraries of this two main work environments. The applied software perform the operation to drive the data loggers, to record the instruments values, to reduce (convert) them in engineering units (i.e. kPa for differential pressures, MPa for absolute pressures, etc.), to print and plot the results and to store the data into appropriate magnetic media. The applied software consist in a set of program integrated into a Sinilar Operative System Utility that only allows standard and tested operation. Inside these programs there are same subroutines (i.e. the calculational subroutine that I elaborates flow rates or water levels, etc from real time values) that are treated as verified engineering calculation. The software that drive the digital data loggers RTVAX300 is transparent to the users and will run in backgruond during the i experimental operations. In particular this data acquisition system is based on a network architecture in which there is one control and elaboration unit and same remote unit with data sampling function as showed in fig. 4. Every remote units is linked to each other in a star logical configuration with the information flow from the central control unit to the remote O unit chain. and viceversa. beetwen the remote units. In fig. 5 Isn't considered is showed any communication the measurement The entire activity of control, acquisition and elaboration is divided beetwen same specialized task. Inside the remote units the communication task dialog using Mailboxes and shared area memory. This Mailboxes are FIFO type communicating channels. When a task want get information starts an own input Mailbox. Two specialized tasx (NET _IN and NET _OUT) routing the communication beetwen tasks resident on dif ferent remote units . A task that send information to another task on a different remote unit put the message and the address of the target into the NET OUT Mailbox that write this message to NET _IN task on target remote unit. In fig.6 is showed a simple example of inter-task communication. The data acquisition process is performed using- same tasks resident on different remote units. The peripherals units sample the physical signals and convert they in number. This number are sended to the control unit where goes on the first elaboration and the data are permanently stored on disk. Tne kernel of the process of acquisition and elaboration is. costituited of a shared area memory that contains the image of the earlier acquired data of all the active measurements channels. Around this kernel runs same specialized tasks as snowed in fig.7. In particular there're three tasks : O

- updated acquisition's parameters image (alarm, sampling frequency,ecc...) This structure reflects all the ,
changes in the system parameters modified by the user during data acquisition process.
- one image (temporal shift window) of data.
This area is a buffer for build the data structure on disk. The data organization has the same logical structure in memory and i on disk store unit. This structure is a bidirectional linked list as showed in tig.8 .The data acquisition process measure the trend of a phenomena during a period and will handle a sequency of value for each measurements channels . The condition in which the value will be costant for an amount of sampling is foreseen to allow a best use of mass storage space. The elementary unit of acquisition is the DATA that represents the measure make or calculated for one time and for one acquisition channel. To handle a very large amount of data and allocate memory the process use a structure derived from the DATA: the DATA _ BLOCK. This is a fixed long structure that contains :
- sequentially sampled data array
- auxiliary informations
- forward and backward DATA _ BLOCK pointer This DATA BLOCK structure is contained
~
into another high level structure named ENTRY BLOCK with the links to first and last DATA BLOCK structure,too. Starting from ENTRY BLOCK and tracking the Torward link chain is possible known the history of acquired data, or backstepping it using the backward link (for example see the last 50 points). When the sampled data fill a DATA _ BLOCK it's stored into a disk's file and is allocated another DATA BLOCK in which put new data. Before . DATA _ BLOCK saturates the memory _ the process discarge the oldest DATA _ BLOCK to free space for new data. The dimension of this temporal window is function of channels number and their sampling frequency. There's one ENTRY BLOCK structure for each measurement channel.

2 j ! sIET Docua6nt Rev. Check Page of i Soz. Reattori Innovativi 0009 SED 91 lA l 7.3 Data analysis The data analysis will be portormed in order to evaluate the goodnes of the experimental test. During the experimental phase the operators will perf orm a monitoring of the measurement values in order to verify the most important test' parameters and to i check the congruency of the values. If necessary an on-line intrument check is tsreseen in order to recover the error. A quick look report will be prepared in order to provide the needed to proced with the ptoparation for the next test. This , document will consist primarily of indentification of the instrument which have failed or performed incorrectly during the test, verification that the objectives of the test were achieved, , and the control of the structural data to insure the integrity of '
- the condenser. More detailed information will be performed in the
" preview" phase that has the purposes of providing representative results from the most significant measurements to be used in the
" Apparent Tut Results" report, and to aid in defining the remainder of the analysis. The time history plots and digital data tables of key parameters will be performed and examined to determine time periods of significant interest for mere detailed analysic. The plots and tables for the Final Test Report will be generated in the " full processing and analysis" phase which han the purpose to organize the data in a form that provides an O integrated interpretation of the performance of the condenser and demonstrate that the objectives have been achieved.
test results to show the 7.4 Data records The digitally acquired data values will be directly write on magnetic disk in real time for the entire duration- of _ the experimental test. Immediately after the end of the experimental test will be done a copy of the data file on a magnetic streamer tape in order to have a saved image of the data file. More will be copied into the magnetic streamer tape the complementary information about the experimental test: the transducers, the physical input channel, the measurement channels, the alarm, the 1 action archivies and the monitor page archivios. The information about daily. instrument check, about the happened alarm conditions, the change operated by the user.inside the database will be logged in relative file and saved on magnetic streamer tape too. The analogically recorded data will be acquired on analog tapes at the tape speed reported in table 2. The sampling of these data will be performed only during interesting transient. In according with the tape speed chosen the- life of a 3600" analog magnetic tape will be about 3500 s. She analog tapes will be replayed through the FFT device and the resulting information copied and stored on magnetic disk for future interpretation and analisys. O
