4.1 .A' Verb List is provided in Appendix IV to this. #

' procedure to provide guidance and examples of action

, and transitive verbs that should be used.

.4.2 ~Many other terms that have specific meanims in the TRIP procedures are defined in reference 1. An ,

example of these is the word "_ operable" or :

" operability".

~4.3 Definition of ."shall",("should", and "may": "shall" denotes a requirement; "sixx11d" denotes a ~

reccanendation; "may" denotes permission,; but is neither a requirement not. a recomendation.

7.5.2 T-200 Series Procedures The T-200 procedures are produced on a computerised word rocessor (i.e. Ans), and therefore, the ava lable type will be used. :

7.6 Applicability' The TRIP procedures apply to both units at the site.

7.7 Verification and Validation 0/sv) 7.7.1 Verification and validation shall be performed in accordance with Appendices VI and VII respectively by the preparer.

7.7.2 POBC or NRB may request additional V&V.

Calculations'which must:be. performed during'the execution of a prorw bre may be;. included an'the flow charts,-however.:

yaidares should be written to avoid the-need for calculations -

e

'when possible.. -

5.3.1 . Calculations shall be labeled with the name.of1

the parameter being calculated and'the unitsi i which the parameter will be defined in following .

_ , completion ~of. the" calculation :(e.g. Contalment, Level'in Feet). f This;1abel.shall appear at the top of each calculation and shall be underlined. --

5.3.2-Calculations!shall.bedisplayed.inalvertical:

format.with the "21mlation proceeding frcst top 11 v-to' bottom.

i 5.3.3 Operatives such as plus,'minus, and equals shall

' be spelled out in the right column ~of the - 3 3 ,

calculation'with the corresponding operation symbol appearing in parentheses imediately to the'right.- ; s 5.3.4 ' The middle coban of each calculation shall

, consist of lines for recording calculated or constant numbers.

' 5.3.5 The left coltan of each calculation shall contain the units of the' number displayed in the middle column._ The. units may be followed by.the parameter nane and the instrument number on which

,. the parameter must be read, if appropriate. '

5.3.6 An example of a typical flow chart calculation is F provided in Attachment III.

5.4 Use of Tables..

k Tables may be used on the flow charts to display infor- ,

L mation associated with a particular procedure step or to segregate flow paths within a procedure.

2. Pr'ooedure Numbering

[ '

- 2.1' TRIP procedures should be numbered to closely parallel- '

' the BWR Owners' Group Emergency Procedure Guidelines - '

(reference 6.3). Where'. additional procedures ~not j specifically delineated in. reference 6.3 are to be generated, they should be numbered to follow along-with the previously written TRIP procedures. The 110 series TRIP gvcedures should be numbered so that the last digit of the procedure number is the same 'as'the ~

. EPG contingency number.

2.2 T-200 Series Procedure Numbering

~

2.2.1 'T-200' series TRIP procedures should be ntmibered ,

' so that'they can be grouped by similar subjects. Examples of T-200 series procedure numbers are given in Table II to this Appendix.

2.1.6 Words and meanings-shall be consistent throughout-the

- flow charts.-

, 2.1.7 - Use only accepted abbreviations and' acronyms that are i-familiar to thef operator, i.e., the ones listed in Appendix VIII.

2.1.8 Avoid the use of time dependent operator actions.

e 2.1.9 - Usa units of measure that are familiar' to the. operator.

i- .

The operator should be able to relate the units to those referenced on the plant instrumentation without conversion, translation or mental manipulation. -!

charts.. However, it is permissible to use them if this simplifies the procedure.

The standard sentence syntax'is to'bes:

~

' a.2 c Begin the command with- the action verb. : Use

1

' :a.3 JThe direct object is required to identify on:

'which equipment the. action. verb is operating.,

. a.4 The indirect object further clarifies the action, if required.-. It is omitted if not. required-for clarity.

a.5 Example Connand:z . .

" Initiate Injection into the vessel'."

You (stabject-omitted)1 initiate (action verb)-

injection. (direct object) into the vessel-

.(indirect object-omitted if not' required for

'~

clarity).

b. Decision Steps: .f b.1 Begin the question with the' transitive verb i

=(e.g., is,.can,'are, has). Use verbatin Appendix IV, if not use connon transitive verbs.

, b.2. The subject is required.to indicate' what action, condition, or paramter is being interrogated.
