S-IDP-PO OUTLINE FOR IhC PROCEDURES A.O PURPOSE This document is designed to explain the scheme of procedures used by the Instrument and Control Department at the Nine Mile Point Site.

Further, it provides guidance for revision and generation of desirable departmental procedures.

B.O REFERENCE B.l AP-1.0 "Procedure for Administrative Control" B.2 AP-2.0 "Production h Control of Procedures" B.3 AP-8. 1 "Procedure for Service and preventative Maintenance" C.O PROCEDURE CATEGORIES ISP INSTRUMENT SURVEILLANCE PROCEDURE Used to comply with stated Technical Specification requirements.

Example: Surveillance Testing, etc.

Procedure has instrument set point limits and Occurrence .

Report requirements. This category has step verification and requires SORC approval.

ICP - INSTRUMENT CALIBRATION PROCEDURE Used to comply with implied Technical Specification requirements.

Example: Provides calibration of equipment which is used by some other department to meet a Tech. Spec.

requirement. This category has step verification and requires SORC approval.

IMP INSTRUMENT MAINTENANCE PROCEDURE Used generally to provide some repair function or a function to avoid device failure. These procedures should be generic in nature when possible. This category usually requires SORC approval.

S-IDP-PO -1 February 1986

d C.O PROCEDURE CATEGORIES (Cont'd)

IP - INSTRUMENT PROCEDURE Used as a departmental procedure for calibrating non-safety related devices. This procedure category will be generally used for Balance of Plant (B.O.P.) instrumentation. This category normally will not require SORC approval and is intended to be generic in nature.

PROCEDURE NUMBER SYSTEM Whenever possible procedure numbers are to be identified by Plant System number. Example Nl-ICP-W-60, Nl indicates Unit 1 (N2 indicates Unit 2 and S indicates a Site Procedure); ICP is the calibration category. The W is the frequency that the procedure should be performed.

W = Weekly at least once per'7 days M = Monthly at least once per 31 days Q = Quarterly at least once per 92 days A = Annual - at least once per 366 days SA = Semiannual at least once per 184 days C = Cycle - once per refueling cycle The 60 is the plant system number for Emergency Cooling. The procedure title is Emergency Cooling Level Control. The procedure number may bear a numerical or alphabetical suffix to provide for additional procedure requirement within the same system.

PROPOSED CHANGES Require only SORC approval-review sheet to be attached to a copy of the procedure with proposed revision.

TEMPORARY CHANGES Requires a Procedure Change Notice attached to copy of the procedure which indicates the changes and identifies the approving SSS and Supervisor. This procedure is to be submitted to the Unit IhC Supervisor by the next business day following implementation. The used procedure copy requires acknowledgement for each change or group of changes of the SSS and IhC Supervisor. See AP-2.0 and AP-1.0.

S-IDP-PO -2 February 1986

J.

D.O PROCEDURE FORMAT Items under this section are identified by number, the same as in existing documents. A P is provided as a review mechanism to a person when generating IhC procedures.

TITLE PAGE The procedure name and number must appear at the top. For ISP's, ICP's, and IMP's, the procedure number should be the same as the system involved.

For SORC approval three signatures are required.

1. Site IhC Supervisor
2. Station Superintendent
3. Site Superintendent Non-SORC approved procedures require only two signatures (items 1 and 2 above).

Site procedures require the Site IhC Supervisor, Unit 1 Station Superintendent, and the Unit 2 Station Superintendents signatures.

Below the approval signatures a REVISION STATEMENT is added indicating the nature of the revision and pages affected. If the procedure number is changed it must identify the procedure which is superseded.

At the lower right corner of the title page, a statement indicating expiration is to be made. 00 NOT USE AFTER... for SORC'ed procedures 2 years and Non-SORC'ed procedures 4 years from date of issue.

1.0 PURPOSE This section identifies the total accomplishment intended by the procedure. The intended usage frequency should be noted here.

3.0 PREREQUI SITES Indicate actions to be done prior to test, such as:

Establish communications, state jack numbers.

Obtain RWP - where necessary.

Markups - where there is any question of safety.

Time frame - when can the procedure be used.

Conditions which must prevail.

State precautions.

4.0 TEST EQUIPMENT List items which are of major importance with equivalent options when possible. Items such as hand tools, tubing, etc. normally should not be listed unless they are of special significance.

5.0 PROCEDURE Ingredients in this outline whenever possible should be handled as prescribed. Deviations ma be taken as necessar . Most importantly, the work must be able to be done as written with efficiency in mind.

The procedure body should be subdivided by major sections, i.e. 5.1, 5.2, 5.3 etc. are to be titled with capital letters, but not underlined. Subsections 5.1.1, 5.1.2, 5.1.3, etc. are to be used as necessary to accomplish the major section task in a smooth manner.

A constant level of awareness must be kept to assure that the procedure flows smoothly, is easy to use, and review. Care in use of words will reduce ambiguity and keep bulk to a minimum.

desirable to state detailed work functions which are obviously within It is not the capability of the technician. "NOTES" and "CAUTIONS" should be inserted at appropriate places to emphasize awareness of problem areas.

5.1 PRELIMINARIES

5. 1.1 First obtain permission from SSS for procedure use.

The procedure body and/or data sheet should identify key consequences in capital letters i.e. scram, jumpers required to Block..., sw position, etc. Discuss such consequences and request any desired markups. Obtained signature and date from the SSS.

EXAMPLE: In capital letters, enter the major cautions which may effect plant operation.
