Reference:
Program Procedure 1201A01 (formerly DPM No. N7203), DPM No. N82S1 C16 1.0 PURPOSE 1.1 The clearance procedure is the method used in the Office of Nuclear Power (ONP) for the protection of workmen, the public, and equipment.
This includes but is not limited to electrical circuits, hydraulic equipment, mechanical equipment, or other devices.
1.2 This procedure contains essential basic information concerning types of clearances and the protective tags used with each.
This procedure has been developed for employee protection.
In order to be effective, it must be understood and rigidly enforced.
J 1.3 In addition to compliance with the general instructions, all employees are responsible for conforming to all applicable special instructions.
2.0 GENERAL REQUIREMENTS 2.1 The standard TVA tag system shall be the only recognized method of clearance.
The appropriate protective tags must be properly applied in all instances.
2.2 The shift engineer (SE) and Chickamauga load dispatcher (CLD) are the issuing authorities at Sequoyah Nuclear Plant.
The CLD issues clearances on switch yard equipment only.
The SE is responsible for issuing all clearances at Sequoyah Nuclear Plant through his representatives, which are assistant shift engineers (ASE), outage coordinator, or other SEs assigned to his shift.
Henceforth in this instruction the SE will mean j
himself or any of his representatives.
l 2.3 Work on any equipment shall be performed under the l
applicable clearance procedure, unless authorized by the craft supervisor and SE.
Clearances shall be issued only by authorized persons and only to those people whose names appear on official clearance lists.
2.4 A clearance is established by the use of protective tags placed so as to indicate the main point of control and the boundary of isolation.
r 0002A/ TAC
~
6, SQN AI-3 page 3 Revision 33 2.0 -GENERAL REQUIREMENTS (Continued) 2.5 protective tags shall not be applied, altered, or removed except under applicable established procedures by authorized employees.
2.6 Each person working around equipment that is involved in a clearance is responsible for determining and recognizing the boundaries established by protective tags and the conditions imposed by the protective tags and must in no way violate the areas and cohditions outlined.
2.7 Safety grounds are to be placed in accordance with the provisions of AI-3, Section 10 when required for the protection of employees working on equipment.
The grounding procedures do not cover every particular grounding application; but, if the principles involved are applied with discretion and judgment, safe working conditions will result.
2.8 Unauthorized cards or tags of any type must not be used on plant or yard equipment to supplement or supercede the cards provided for in the Clearance Procedure.
2.9 A TVA protective tag will never be used unless it is a part of an official clearance request and bears a properly assigned number.
Clearance tags will not be used for any purpose other than that for which they are intended.
2.10 Drain or vent valves when required to be left open to prevent pressurization of a system within the clearance boundary shall be tagged open with the words " Valve Tagged Open" written on the clearance card.
2.11 No equipment contained in the technical specifications shall be removed from service for planned maintenance or surveillance testing unless the opposite train is operable (operable means within the time limits of its last surveillance test) except in an emergency.
Exception to this would be the diesel generators where surveillance testing of other diesel generators is required.

e SQN AI-3 Page 4 Revision 33 2.0 GENERAL REQUIREMENTS (Continued) 2.12 When-tagging a breaker open that gives an alarm, if it is to be open for greater than one 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> shift, the electricians shall lift the wires to annunciator and initial clearance sheet.
The ASE will tag the disconnected leads with a H.N.
When the clearance is released the electricians shall connect the annunciator i-wires and double verify it on the return to normal section of clearance sheet.
This is to prevent nuisance alarms while a breaker is tagged out.
2.13 Clearances handled from a clearance book inside the
" POWER BLOCK" to operators performing clearance work outside the " POWER BLOCK", or vise versa, should be handled in the same manner as receiving and working an electrical dispatcher's clearance.
For documentation of the individual who performed the clearance work (ie, verified equipment ready for clearance and placed cards or released clearance) the person receiving this information-shall print the last name of the operator 4
I who performed the work then initial the appropriate '
block on the clearance sheet.
Double verification may be handled in the same manner.
3.0 PROTECTIVE CARDS AND CLEARANCE SHEETS 3.1 Protective cards (a description and brief explanation of their use follows).
3.1.1 Hold Order (form TVA 6270) i This red tag is normally used as a master tag for the clearance.
It is usually installed on i
the main control point to isolate equipment from all sources of energy and to permit work to be safely performed.
The red hold order card may be placed on the unit's cork board or stapled to l
the clearance sheet per Section 3.1.10.
It also I
serves to protect the equipment itself from l
damage.
A hold order must never be placed upon any equipment which is energized or in service.
Equipment must never be energized or placed in service until after the hold order has been released and the card removed.
A single hold order tag (red tag) is used on any given clearance while clearance boundaries are i

5.0 METHOD FOR OBTAINING A CLEARANCE 5.1 Requesting a clearance 5.1.1 The person requesting the clearance will inform the-SE on duty as far in advance as possible to avoid delay in getting equipment out when needed.
When possible, requests for clearance should be given to the operations supervisor or the SE a day in advance of work to be performed.
This will allow the evening and midnight shift operators to perform the clearance work.
The SE shall make every effort to have equipment clear for maintenance at the time requested.
5.1.2 He will state the equipment to be cleared, the nature of the work to be performed, the date and time he desires the clearance to begin and the approximate time required to complete the work.
5.1.3 Except in the' case of new construction, equipment shall not be held out for indefinite periods.
Persons requesting clearances must estimate as closely as possible the time necessary for completion of the work and report these estimates to the SE.#
The SE should be notified immediately of any reason that may make it difficult to place the equipment in service at the scheduled time.
5.1.4 A clearance shall be issued by number and is not complete until the last tag is placed and the issue time is given to the person requesting the' clearance.
Regardless of the presence of a tag, all equipment must be considered energized unless it is known to be within the limits of a clearance which has been issued and not released.
The presence of a hold notice or hold order tag does not ensure that the equipment is under clearance.
