- PUBUC SERVICE COMPANY OF COLORADO 1.0 OBJECTIVE
- See Commitment 7.1*#*
This document provides specific administrative and technical guidelines for preparing Fort St.
Vrain Emergency Procedures.
2.0 SC0pE Tt.i s procedure applies to the development and revision of all Emergency Procedures, including those dealing with specific emergency events and those dealing with the monitoring, maintenance, and restoratien of critical safety functions.
3.0 GUIDELINES FOR PROCEDURE pREPA'RATIDN The Emergency Procedures should be concise, but adequately detailed to ensure that the Control Room Operators are provided with unambiguous guidance for emergency plant operation.
~
3.1 PROCEDURE REVISIONS Revisions to this Writer's Guide and to the Emergency.
Procedures shall be reviewed and approved in accordance with the Fort St. Vrain Administrative Procedure G-2 requirements for Level III, Emergency Procedures.
l l
3.2 GENERAL WRITING GUIDELINES
- 3. E.1 Each procedure step should deal with only one idea.
3.2.2 Complex evolutions should be prefaced by a short general requirement and then described, as simply 1
as practical, on a step-by-step basis.
1 3.2.3 Non-sequential step sequence should be stated.
3.2.4 Each action step should be presented as a command composed of one or two complete sentences.
3.2.5 As a guide, sentence length should not exceed 20 words. Long complex sentences are less effective in communicating the intent of the procedure.
3.2.6 Objects of Operator actions should be specifically stated.
3.2.7 The basis, or reason, for an action should not be included in the procedure.

0AP-2 Issue 1 Public FORT ST. VRAIN NUCLEAR GENERATING STATION Page 4 of 18 0 Service ~pusuC SERVICE COMPANY OF COLORADO 3.2.8 Limits and values should be expressed quantitatively. Tolerances should be expressed by i
indicating the entire range (e.g., use 10" to 20" rather than 15" t 5").
3.2.9 Human engineering and ALARA factors, such as sequence of operation, reduced memorization, no mental calculations, and early action to prevent radioactive release from the plant site, should be incorporated into Emergency Procedures.
3.2.10 When actions are required based on activation of an annunciator, the setpoint of the alarm should be listed to facilitate verification.
3.2.11 When resetting an automatic function, the expected plant changes as a result of the resetting action, should be listed.
~
3.2.12 A note should be provided to notify the Operator prior to the performance of any step that will activate an annunciator.
3.2.13 When additional confirmation of system response is -
considered necessary, the additional indications to
~
be observed, should be listed.
3.2.14 Describe the system response time associated with performance of a step, or series of steps, when it is considered important to the Operator for proper understanding and performance.
3.2.15 The Operator should not be referred to any other document, reference, or procedure for actions required to mitigate the challenge to a Critical Safety
- Function, except another emergency procedure.
3.2.16 Expected results of routine tasks or evolutions need not be stated.
3.2.17 Do not split procedure steps between pages.
I 3.3 LEVEL OF DETAIL 3.3.1 Emergency procedures shall consist of a series of steps and substeps. The steps shall be written in the form of a command that tells the operator what to do (e.g.,
start one ' circulator using the emergency condensate system as motive power).' The substeps should then tell the Operator, in more detail, how to accomplish the step.

-.. ~.
OAP-2 Issue 1 FORT ST. VRAIN NUCLEAR GENERATING STATION Page 5 of 18 0 Public service
- PUBUC SERVICE COMPANY OF COLORADO 3.3.2 Each step should be written in the degree of detail to allow a qualified Operator to understand what must be done to complete the step.
3.3.3 Each substep should be written in enough detail to specify to a qualified Operater exactly which control; and displays should be used to complete the substep.
3.3.4 Each substep should contain enough detail so that relfance on the Operators' memory is kept to a practical minimum.
3.4 PUNCTUATION Punctuation should be used only as necessary to aid reading and prevent misunderstanding. Yord order should be selected to minimize punctuation.
If extensive punctuation is necessary for clarity, the sentence should be rewritten or made into several sentences. Punctuation should be in accordance with the following rules and Fort St. Vrain Administrative Procedure G-2.
3.4.1 Use a colon to introduce a list of items.
3.4.2 Limit the number of commas to ensure that the procedure is not too complex or awkwardly constructed.
3.4.3 Use a period at the end of a sentence and to indicate decimal places.
3.4.4 Use brackets to indicate options in equipment lineup (e.g.,
Start one nitrogen compressor C-2109[C-21095] with HS-21431[HS-21432]). Brackets are not to be used when the Operator is to operate all of the designated component's. The procedure should be written so that once an option is
- selected, it is followed clearly and consistently throughout that section of the procedure (e.g.,
CoolersE-5109X[E-51095X]).
3.4.5 Use parentheses to set off referenced figures, tables, appendices, etc.
3.5 VOCABULARY Words used in procedures should convey precise meaning to qualified individuals. The following rules should apply:
3.5.1 Use short, common words of few syllables.
Po W @ M 22 384
OAP-2 Issue 1 Public FORT ST. VRAIN NUCLEAR GENERATING STATION Page 6 of 18 0 Service ~ pusuc sERvlCE COMPANY OF COLORADO 3.5.2 Use non-technical, common usage if it makes the procedure easier to understand.
3.5.3 Minimize the use of "a", "an", and "the" unless they are needed for clarity.
3.5.4 Avoid specialized or abstract words when synonyms are available.
3.5.5 Use action verbs in instructional steps to denote a particular action that the Operator must perfom.
3.5.6 Common action verbs and their applications are provided in Appendix 1 as a guide.
3.6 NUMERICAL VALUES The use of numerical values should be consistent with the following rules:
3.6.1 Arabic numerals should be used.
3.6.2 For numbers between zero and one, the decimal point should be preceded by a zero (e.g., 0.1).
3.6.3 For numbers less than zero, a minus sign should precede the number (e.g., -0.1).
3.6.4 The operator should not be required to read an indicator to greater precision than is displayed by the indicator.
3.6.5 Engineering units shoule always be specified for numerical values of process variables and should be the same as those used on the panel displays (e.g.,
psig instead of psi).-
3.6.6 Units of measure should be given numerical values that represent observed or measured data and calculated results.
A virgule (/) should be used instead of "per" (e.g.,
ft/sec, micromho/cm, and 1bs/hr).
3.6.7 Scientific notation values should be indicated by the capital "E" followed by a plus (+) or minus (-)
(to indicate sense) and the value (e.g., 3.2 E+12, 1.7 E-06).

OAP-2 Issue 1 Public FORT ST. VRAIN NUCLEAR GENERATING STATION Page 7 of 18 0SerVIC9" PusuC sERVlCE COMPANY OF COLORADO 3.7 COMPONENT IDENTIFICATION 3.7.1 For steps, components should be identified by their piping and instrumentation (P&I) component identification number and common name [e g., Start Buffer Helium Recirculator (C-2105)].
For
- substeps, equipment and controls should be identified by,the handswitch number, P&I component identification number, panel number on which the control switch (or display) is located, and the placard descriptica ts provided on the panel. For the above example, the single substep might read
" Place HS-2193 (C-2105 Buffer Helium Recirculator) on Panel I-02 to the START position and release."
3.7.2 Annunciators should be identified by quoting the annunciator window verbatim followed by the panel number and grid coordinates of the window enclosed in parentheses [e.g., SERVICE WATER COOL TOWER FAN TRIP (I-06G,1-7)].
3.7.3 When referencing specific engraved names and numbers on panel placards and annunciator windows, the engraving should be quoted verbatim and emphasized by using all capitals [e.g., verify that SERVICE WATER COOL TOWER FAN 1A VIB HIGH (I-06G, 2-7) annunciator is reset].
3.8 CALCULATIONS Calculations should not be required to perfc.a steps or substeps in emergency procedures. Retrieving a value from a chart or graph is permissible, but requirements to do so should be kept to an absolute, practical minimum.
~
3.9 ABBREVIATIONS AND ACRONYMS Except when identifying controls and displays in substeps, abbreviations and acronyms should not be used.
