MAINTENANCE INSTRUCTION FOR WRITING PROCEDURES GENERAL RE UIREMENTS The following guidelines are given to ensure Nine Mile Point Units 1 and 2 Maintenance procedures conform to formats and procedure development as
'pecified by NMPC. This instruction to be used for all types maintenance procedures except for surveillance procedures. This instruction enhances the administration procedure AP-2 Production and Control of Procedures.
Procedure titles shall describe the purpose of the procedure. If the procedure is for preventive maintenance, the title should include frequency.
2~ All procedures shall have an unsigned "NMPC Title Page" to identify the type of procedure generated.
3~ When information is unavailable to generate a complete procedure "rough draft", the procedure shall have a "LATERS PAGE" attached.
Each identified item on the "LATERS PAGE" shall include the step number of the "LATER" and should include a description of the required information for each "LATER". Unavailable information shall be identified as (LATER) in the procedure text. All "(LATERS)"
should be resolved prior to writing the "final draft."
4~ Procedure cover sheets, margins and spacing, page numbers, revisions, and dates will comply with AP-2.0 Production and Control of Procedures. A table of contents may be included in the procedure.
- 5. All NOTES, CAUTIONS, and WARNINGS (not to be confused with Section 5.0 PRECAUTIONS AND LINIT~ATIONS shall be capitalized, undetlined, and placed before the applicable steps.
5.1 NOTE: Refers to general information or for clarifying purposes regarding the step performance. For example:
"NOTE: In the following step, refer to Figure 4 of Attachment 10.1 for identification of parts."
5.2 CAUTION
is applicable when the actions of the person(s) performing the step/task may cause possible equipment damage step/task is not performed properly. For example:
if the "CAUTION: In the following step, use care to prevent the stem/disc assembly from dropping out of the valve bonnet during valve bonnet removal."
S-MI-GEN-002 -1 March 1986
V%
5.3 l/ARNENG: is applicable when the actioas od the person(s) performing the step/task may cause possible personnel injury and/or death if the stepltask is not performed properly. For example:
"WARNING: In the following step, loosen all vessel cover nuts in a star or criss-cross pattern and ensure all torque loads are removed from each stud before removing the nuts. Random removal of the vessel cover nuts will cause an increasing load on remaining fasteners which might cause the fasteners to fail and allow the cover to flip off the vessel."
5.4 Generally, the use of notes should be minimized. Substeps or steps are preferred.
- 6. If an abbreviation is used in the procedure, define it the first time used. For example.'RD (Control Rod Drive).
7~ Terms Denotin De ree of Action 7.1 "Shall" is used to denote a requirement.
7.2 "Should" is used to denote a recommendation which, if not acted upon, will require an explanation justifying the action taken.
?.3 ~s May
~ I is used to denote, permission, neither a requirement nor a recommendation.
7.4 "Will" is simply a statement of what is to be done or what is expected. It is neither a requirement or a recommendation.
7.5 The terms defined, in Section 1 of the Technical Specifications shall be effective for all procedures and orders generated at the site.
8.0 Data Sheets in the body of the procedure shall be used when the procedure is extremely short or the frequency of performance is extremely long which would not allow maintenance personnel to become intimately familiar with the procedure.
9.0 Ranges shall be expressed in accordance with NUREG 1369, Rev. 1. For example: 125 (119-131) gpm acceptable (preferred).

(standard statement). The plant impact statement should follow this step.
6.4.1 Plant Impact S-MI-GEN-002 -7 March 1986
6.4.1.1 The beginning of the procedure, near SSS permission step, shold address plant impact while performing maintenance. If there is no impact, mark the statement N/A (not applicable). System description should be referenced to determine plant impact . For example:
(1) "PLANT IMPACT Maintenance on isolation valves makes one isolation valve inoperative. The other isolation valve should be marked up accordingly."
(2) "PLANT IMPACT The equipment marked up will not be available for service."
6.4.1.2 The plant impact should include a statement with regard to the effect of lifted leads, jumpers, or blocks and the plant impact. This should be included when the leads lifted are not addressed by a markup per AP-3.3.1. For example:
"PLANT IMPACT- A jumper is installed to block cleanup isolation when the squib valve control switch is operated."
6.5 Notify CSO and initial on data sheet (standard statement).
6.6 Markups may be described here using a list of applicable equipment.
- 6. 6.1 The markup section may also include any disabled annunciators or lifted leads/jumpers required to markup the equipment. For example:
"Remove the 74A relay for low care spray suction pressure."
6.6.2 The markup provided are recommendations, and thus, may change with system or plant conditions.

7.0 PROCEDURE 7.1 Include step by step details to perform maintenance and/or obtain data. Limits for data should be identified and the as found and as left data should be recorded.
7.1.1 Use of abbreviations should be minimized. Commonly used acronyms are acceptable.
7.1.2 Steps should be short and concise and generally contain one action per step. Where more than one action is to be incorporated into a single step, one action should be the result of the other or need to be done simultaneously with the first.
7.1.3 Initials, signatures, and data will normally be recorded on the Data Sheet (see Section 10). Initials, signatures, and data may be recorded in the body of the procedure for very short procedures 'or for those with extremely long frequencies.

7.1. 7 Consult AP-3.3.2 (Supersedes APN-7A) and IE 84-37 when using lifted leads and jumpers. Leads lifted in a procedure should have independent verification.
7.2 The beginning of the procedure may include a section identifying general requirements or describing the general test method.
Include QC inspections, where required, in maintenance procedures.
Generally, PM's are covered by QC surveillance.
S-MX-GEN-002 -9 March 1986
- 7. 3.1 Maintenance considers QC signoffs as hold points. QC inspection plans detail witness points and hold points. QC may waive hold points with written documentation. Maintenance may proceed past a QC hold point with other activities provided the steps don't prevent QC verification of the hold point. Hold points are signified on the data sheet as "QC /
7.4 Notify ISI Coordinator and I&C Supervisor (if applicable) that maintenance has been completed. (standard statement) This standard statement should be before maintenance testing.
7.5 The final steps at the procedure should address maintenance tests which are performed as part of maintenance testing. The post-maintenance test register should be used to determine the required tests. For example:
"Maintenance tests Check motor rotation is correct for driven equipment."
7.6 The final steps should notify-other support departments to complete any associated maintenance activities and their related tests. For example:
(1) "Notify electrical maintenance to replace the valve operator."
