+1.3.9 10/31/83 OLUMK NAMC ADMINISTRATIVE PROCE E ON 1.3 CONOU T OF OP AT N CONTROL OF ELECTRICAL AND 1.3.9.1 ~Pur oee The purpose of this procedure is to establish the method of controlling electrical and mechanical jumpers, and lifted leads.

1.3.9.2 References A. ANSI N18.7-1976, Section 5.2.6 (Equipment Control)

B. Operational QA Program Description C. PPM 1.3.6, Shift Turnover D. PPM 1.4.1, Plant Modifications 1.3.9.3 ~Sco e A. This procedure shall be used for all safety-related and non-safety-related systems.

B. This procedure applies with the following exclusions:

1. This procedure does not control the use of "installed bypass",

i.e., key-lock switches, bypass switches, mode switches, and test devices which are used in accordance with other appro-priate plant procedures.

2. Electrical and mechanical jmpers or lifted leads which are positively identified in approved procedures are excluded from the requirements of this procedure. To qualify for the exclu-sion, the other procedure must:
a. Clearly specify that the Shift Manager must be notified prior to installation and removal.

b. The other procedure identifies the need for independent verification of installation and removal (if required).

C ~ If the procedure is completed or delayed for more than one shift, the jumper or lifted lead. must be returned to norm-

, al or the control of them transferred to the provisions of this procedure.

d. Pipe caps or blank flanges used to stop leakage are visi-ble from the isolation valve are excluded from the re-quirements of'his procedure.
e. The, jumpers or lifted lead tags are controlled by the Shift Manager and are issued by him to the procedure .used to control the work.

NOTE: PM/Calibrations done as part of'HS or trouble-shooting done peran approved MWR qualify for this excep-tion. The need f'r independent verification will be noted on the task card or HWR where applicable. This need will be identified by the Maintenance Supervisor based on ex-perience, job complexity and for importance to safety. In both cases,, the jumper, lifted lead or mechanical jumper shall be removed immediately when work is completed or suspended.

3. With the exception of B.2 above, jumpers and lifted leads shall not be used to incapacitate a system required to be operable by the Technical Specifications. Jumpers or lifted leads on safety-related systems except as noted in B.2 constitute a system modification and shall be controlled in accordance with PPM 1.4.1.

1.3.9.4 Limitations and Precautions (See body of procedure) 1.3.9.5 Procedure A. Controls

1. The jumper and lifted lead log shall be maintained by the Shift Manager in the Control Room. This log (example included in this procedure) shall contain the location of all electrical and mechanical jumpers and lifted lead tags in use within the conf'ines of the plant site. An up to date index list similar to Attachment II of jumpers and lifted lead tags presently available for use and their identifying numbers, shall be main-tained in the front'of the jumper and lifted lead tag log, similar to Attachment I.

There shall be one set of distinctively colore'd electrical jumpers sequentially numbered for accountability.

02'.

There shall be one set of distinctively colored lifted .lead tags sequentially numbered for accountability.

Mechanical jumpers shall be uniquely identified and their stor-age location identified where applicable.

Jumpers which are installed between cabinets or are of a length that both ends are difficult to identify shall have the identi-fying tag attached to both ends.

6. Electrical jumpers and lifted lead tags shall be maintained under the control of the Shift Manager and shall be accounted for once per day per PPM 1.3.6. A daily inventory of mechani-cal jumpers is not required..
7. The installation of jumpers and or the lifting of leads shall only be accomplished with the permission of the Shift Manager.
8. Jumpers and lifted lead tags shall not be permitted to exist in plant systems any longer than reasonably necessary.
9. The Technical Manager shall have the jumper/lifted lead log reviewed at least quarterly and reported by memo to the Plant Manager. This review is intended to identify those items which should be removed or processed per PPM 1.4.1, Plant Modifica-tions.
10. Any time a jumper or lifted lead tag is lost or removed from service f'r any reason, .the number of that jumper or lifted lead tag shall be permanently retired from the log index.

Lifted leads shall be suitably insulated from other circuits and from ground and jumpers must be compatible for the use in-tended (e.g., size, terminal type, insulation).

12. Independent verification or functional'est shall be made for the selected location and the physical installation or removal of jumpers and lifted leads on safety-related or fire protec-tion systems.
