'4.9 All tubes slated to receive stabilizers have been identified and those identifications have been verified by Quality Contro1.

4.10 : All stabilizer installation tooling shall have unique serial numbers assigned to each tool prior to use.

4.11 Installation Tooling Qualification NOTE: These tests are to be performed at the beginning and end of each shift or when the tooling is changed. Do not adjust tooling for post installation. tests.

NOTE: All results of the Holder and Crimper Qualifications shall be documented on Attachment 7.2.

4.1!.1 Holder Qualification (1) Clamp a special vice grip holder onto the , ,

modified bolt of crimp tool qualification device.

. (2) Apply a torque to the bolt head using a torque wrench until the modified bolt held with the speciai vice grip holder slips, or until a i

maximum of 20 ft/lbs is reached. l

-(1) Place tested vice grip holder in the middle of the stabilizer part of the crisp tool qualification device.-

(2) Insert the' Modified Bolt into the other end. i l

(3) Crimp the joint with a special vice grip l crimping tool previously adjusted.

(4) Using a torque wrench on the bolt specified in Step (2), measure the torque required to cause 4

the joint to rotate. This must be greater than <

8 ft/lbs.

(5) If crimp slips at less than 8 ft/lbs, adjust the vice grip crimping tool accordingly and repeat Step (4).

p (6) Upon satisfactory crimp test, lock (weld) the-crimping tool adjustment screw and lock nut.

.Rev. 0 5.3 Exercise extreme care to prevent dropping tools or parts

- inside the OTSG or piping since such an' accident will result in lengthy retrieval operations. Use of nylon lanyards or equivalent means of positive capture is required.

5.4 Prior to performing welding operations, drop to minimal' nitrogen overpressure and water level to .at least 12" below secondary face of upper tubesheet.

5.5 Observe all applicable limits and precautions of the Radiation Protection Plan and RWP.

q Int r Offim Mcmcrander Date- March 15,-1983 Subject OTSG TUBE SEGMENT H 0 FLUSH 22 Muclear 3310-83-081 To B. 'D ELAM,. MANAGER - MEGANICAL Location Three Mile Island SYSTEMS, TEG. FUNCTIONS, PARSI? PANT 1.) Background. Materials Engineering has requested Plant Engineering to develop a method tf inserting tube segments pre-viously pulled from the OTSG's back into the reactor coolant flow path during the H 0 Flush. These tubing 22 segments would be periodically w:Lehdrawn to determine if the desired cleaning effect is being achieved.

AAA4 Hem _al tube segments could also be reinserted into

~

the flow path if desired.

2.) Method. '

Plant Engl.neering proposes that the tubing originally installed to measure the d/p across the A and B Reactor Coolant Pumps be utilized for this' testing. The tubing is still installed and, as shown in Attachment 1, ter=-

inates on the D-ring wall right next to the door used to gain access to the D-ring. Differential pressure i

transmitters RC-98A/B -dPIT were initially installed in this tubing but has since been removed from service.

A temporary tubing and valve mni#cid would be connected from the discharge of one of these pumps to the suction of the other. This arrangement would ensure that the reactor coolant flow path would be unidirectional re-gardless of which pump on that side of the reactor in rimn in g. N.. Shah has performed preliminary calculations which indicate that the flow rate expected through this tubing would be about 2 gpm.

The consection to the RCS would not require any cutting or weldings Tubing connections would only require re-connection af ter the completion of the test.

3.)

Tubing Manifold. The tubing manifold itself is shown on Attachment 2.

It would consist basically of isolation valves, cubing reducers, vant and drain connections, a pressure gauge (0 to 500 psig) and a flowmeter (if desired) mounted on a wooden frame to facilitate operation.

. Five segments of OTSG tubing would be mounted in series L as shown. The segments would be mounted by using a 5/8" gg.c ,

' Swagelok fitting. A test segment of simulated OTSG

~

tubing was pressure tested to 1000 psig using this type of Swagelok fitting. No leakage was noted dur-ing this test. Since the presently installed tubing

'is 1/2" O.D., reducers must be used to accomodate the diameter dif'farence. The tubing segments would be connected by short lengths of 5/8" 0.D. stainless steel tubing. .

4.) System Operacion. When either the A or the B RCP is running, a fl'ow of about 2 gym is expected. When it is desired to removed a tube seguent', the manifold would be isolated, drained and vented. The desired tube segments could be removed and new segment installed (if desired) or that section of the manifold could be eliminated -

completely. The manifold would be returned to the RCS flow path by shutting the vent and drain and opening the isolation valves. The tubing segments will be forwarded to Batalle (Ohio) for analysis. No onsite

- analysis is planned.

5.) Administrative Requirements c a.) System Insta2.lation. The system would be Lasta11ed in accordance with the requirements of AP 1013, Bypass of Safety

-Functions and Jumper Control. It will be treated'as a Temporary Mechanical Mo'dification and handled accord-ingly.

j b.) Syntem Operation. The system will be operated in accordance l with an STP generated by Plant Engineering.

l

c.) Safety Evaluation. The safety evaluation will be generated by l the Mechanical Systems Department of Tech. Functions.

l . . This safety evaluation shall determine that such a l test loop i

can be Lastalled and okerated safely at test conditions with respect to pressure integrity of the Reactor Coolant System including any applicable code j requirements.
