1. Purpose The University of Florida Training Reactor (UFTR) identification (ID) coding provides a standardized method of naming equipment, diagrams and signals for the purpose of continuity in identification during the project development process. The Reactor Protection System (RPS) specifications for the project are described in UFTR-QA 1-100, "Functional Requirements Specification (FRS)," /I/.

This document defines the rules for the assignment of ID codes to:

  • Instrumentation and Control (I&C) equipment
  • I&C signals This document forms an essential design input for the Software Requirement Specification (SRS) document.

4. Coding of I&C Equipment 4.1 ID Coding of Field Equipment The ID coding of UFTR's field equipment identifies the devices within the system following the format presented in Table 4. 1-1 (Note that although the maximum number of characters that can be used in the naming scheme of the SPACE Engineering System is twenty characters, not all of the available character spaces are used).

The first two characters are implied as "UF" (University ofFlorida Training Reactor) when it is not included in the ID. The following character is number 1, which shall be used for the reactor Unit Number. The ID code includes inform.ation of the device location (System) and the Device Type. When less than 3 characters are needed for the System code, a space or underscore in its place shall be used. Device type is designated a 2 characters field. In the case of the SPACE Engineering System which does not allow the use of underscores, a blank shall be used. The SPACE Engineering System also will not allow ID codes containing more than one blank between characters. Any additional blanks that would violate this rule should be omitted. Four digits are assigned to the Device Number and, in special cases, additional information can be added to the end of the ID on the three available Suffix fields.

The ID code for the sensors includes abbreviation for the sensor name, the sensor location in the reactor system, and the order of redundant channels. Table 4.1-2 presents the ID code for all the sensors in the UFTR RPS.

If no CPU-ID is defined, the code generators (i.e., SPACE) will assign one. However, it is beneficial to apply a systematic naming scheme to the CPU-ID. For the UFTR RPS, the following scheme is used:

Position I is assigned to the reactor Unit Number which is I for this application.

Position 2, "Component," referred to the components of the TXS system such as Acquisition and Processing (AQP), Service Unit (SU), etc., and the third position 3, "Location" refers to the location within the TXS safety system. Positions 2 and 3 are used together to clearly clarify the place of a CPU within the system. Table 4.3-1 presents a matrix of Component vs. Location.

5. ID Coding for Design Documentation The TXS Software Engineering Tools document the hardware and software in the form of diagrams, which are identified by ID codes. SPACE diagrams are distinguished by diagram type. For additional information on SPACE diagrams, see the SPACE overview document /3/.

5.1 Hardware Diagram Coding Table 5. 1-1 shows the ID code for the Cabinet Overview Diagram (YDN). There is only one cabinet overview diagram for the project. Again, the leading number is the Unit Number 1.

YDRs are named the same as the cabinet equipment ID. According to SPACE specification, ID can have up to 10 characters (see Section 2.1).

These FDs must be named using an unambiguous ID code. The FDs are identified by this ID code. Signal connections between function diagrams carry the ID code of the source FD plus a signal identifier.

The functional requirements are broken down into:

  • Input sub-modules, receiving data from the field or control board;

" I&C Functions, using the data provided by the input sub-modules and providing outputs to the output sub-modules;

" Output sub-modules, driving the output interface to the field or control board /

control panel.

5.2.1 Function Diagram Coding for Input Sub-modules The sub-modules that read field inputs are named using the ID code of the component providing the field input (i.e., the sensors, monitors, etc) in addition to identifying the TXS computer on which these functions are executed. Table 5.2.1-1 represents the coding scheme for the input function diagrams.

Input function diagram naming is established with the primary field device.

Field Component and Main Control Board output function diagrams are named using the ID code of the component they drive. In addition, the Field Component and Main Control Board output function diagram names identify the TXS computer where the function resides on. Annunciator and Event Recorder output function diagrams are named using the ID code of the function they are driven from. In addition, the Annunciator and Event Recorder output function diagram names identify the TXS computer where the function resides on.

6. ID Coding of I&C Signals 6.1 Signal Coding Standard The SPACE Engineering System requires ID codes for signals being exchanged between function diagrams. These signals that are called "external signals" carry the ID code of the function diagram they are originating from, plus a signal identifier. Table 6.1-I defines the coding standard for signals. All signals start with a Function ID Code.

Function ID Code can be (see Section 5):

" Sensor ID

" Sensor liD with suffix

  • Field Contact ID

" Function ID

  • Function ID with suffix
  • Function ID with predefined suffix

" Component ID

  • Component ID with predefined suffix Column I and 2 of Table 6.1-1 define the type of signal. XA is for analog signals, XB is for binary signals, and XM is for monitoring signals. Column 3 and 4 designate different input and output signals with a numerical value.
