- 1. Terporary protection shall b5 provided for the tendons 'during the surveillance.
- 2. The clapsed time between re= oval and replacement of sheathing filler should not exceed two veeks, although no dhleterious effects should be expected if all exposed surfaces are coated with Vic-conorust 2090P or Arber 1601.
II. TE!!D0!!S TO BE I!iSPECTED
- 1. A list ~ of tendons to be inspected vill be obtained from the sur-veillance test Engineer and recorded on data sheet II.1. '~nis list vill consist of 10 horizontal, 5 vertical and 6 done tendons.
The list vill include definition of which of these surveillance a - tendons are to have a vire removed for inspection and tensile strength testing. If for. any reason any of the Surveillance tendons so desiEnated by the Surveillance Test Engineer are - inaccessible or otherwise not able to be tested, alternate ' surveillance tendons vill be designated and such vill be indica-ted on data sheet II.1, with the reasons for the required chanSe-
- 2. Prior to co=mence:ent of the surveillance Data sheet VI.1 page (1) vill be cocpleted as per. steps (1) thru (h) of the data sheet instructions.
III. ADMI??ISTRATIO:s OF p30CILURES DURII?G SL~RVEILLA! ICE
- 1. A copy of the procedure vill be =aintained by each of the two
,S crews perforning the surveillance. (Any procedural changes U
must be controlled in a similar canner for each copy). In addition
, to this copy of the procedure,'each crev vill have -ith the= the i
f ~'
, data package for the tendon under test. This data packcGe e consisting of data sheets IV.1, V.1, VI.1 (pages 1 & 2 and O instructione), vI 2 (reces 1 & 2) v1.3 crece 1, 2 or 3) end v11.1 vill have all information reriuired from past records and al'1 appropriate corputational data required for acceptance criteria entered into them prior to con =encement of the tendon surveillance.
Upon cocpletion of each data package (with the possible exception of the recreasing infor=ation, if a delay is foreseen) the results vill be entere'd into the su. ary sheet (see section XII) revieved by the shop foreman and forwarded to the Surveillance Test Engineer (STE). The STE vill promptly review the data and return C it to the fore =an to be asseb. bled into the procedural package for the entire surveillance. s IV. SHEATHING FILLER INSPECTION
'Ibe sheathing filler (Visconorust 2090P .2 or P h or its equivalent) may be liquid, Eel or solid. All states =ay occur at a particular tendon. Only sufficient filler should be removed, as to allov the required inspection of the stressing vasher, buttonheads etc. -'
- 1. Record the air te=perature both inside and outside Centainment i For tendons which end inside the Auxiliary Suilding the te -
l perature vill be measured in the vicinity of the tenden end. For all others, any te perature representative of a-bient in the G t vicinity of containment is sufficient. (It is not intended I that a thermometer be carried in the skycli=ber just for this purecse). Fecord terperatures on data sheet IV.l.
. ]
[ - 3-
- 2. Upon rc.-oval of the Crease cap from each end of the tendon, collect 2 .1 quart sarples of filler (preferably one quart from each end). Drcin any grense recoved into a barrel in order that an esticate of the volume of grease lost me,y be entered' into data sheet IV.l.
- 3. Perform an exa;:iination of the tenden ends to determine the ex-tent of coveraEe of the sheathing filler and note any apparent presence of water in the filler indicated by emulsification or milky appearance. Indicate on data sheet IV.1 hev the color of the filler cocpares with a sa:ple of new filler.
- h. Submit one sample of sheathing filler from each tendon for chemical examination as per Appendix (3) the " Specification for Laboratory Testing of Eneathin8 Filler"(Visconorust 2090P)
V. VISUAL INSPECTION OF ANCECRAGE C0!!PONENTS
- 1. 'Ihorouchly clean the anchorage corponents with Viscosity 011 ,
i Company's Industrial solvent #16 (or equivalent). Note: Chlor-inated hydrocarbon solvents shall not be used. f i
- 2. Inspect all buttonheads for shape and size using a Co-No-Co
! +0.000 gauge with end inside diameters of 0.3906 -0.005 and 0.359h i
+.0005 t l .0000 (see attach =ent 1) . Ccepare buttonhead status with that obtained from the original stressing records i.e. the stressing ."
cards, Appendix F of the prestressing report, or previous susveil-lance reports. All defective buttonheads vill be indicated on the end anchorage and stressing vasher inspection sheet (Data sheet V.1). If their nu=ber is different frca the nt ber of defective buttonheads previously reported, this vill be indica- ( ted on the inspection sheet. s I

G Record all findings on the end Anchorage and Stressing vasher V inspection sheet (Eata sheet V.1). . .
- NOTE -
The shims do not have a machined surface - they vill seem to have a " scale" somewhat like =iil-scale. This' is not necessari-ly indicative of any corrosion. Rusting and pitting vill probably
, look different.
14 Identify any broken tendon vires - t.Lege vill be readily iden-tified by buttenhead " pop-up". This inspection for buttonhead pop-up should also be conducted after the distress /restress cycle is co=plete and the tendon is reshi =ed, in case friction should socehov present any broken tendon vires from relaxing sufficiently, as to be visible. - O 5. Any defects found during the End AnchoraEe Asse:bly inspection vill be immediately brought to the attention of the Surveillance Test Engineer in order that any special investigator / or reporting - require =ents =sy be satisfied. A sketch vill te =ade of ary defects which cannot be clearly shown on the End Anchorage and Stressing vasher inspection sheet. (Data Sheet V.1) VI. DESTRESSING AND,_ LIFT-OFF !!ES.SURDIENT

DATA SiriET VI.1 DATA FOR STRESSING /RESTRESGIt;G/ LIFT OFF ACCIPTABILITY INSTRUCTIONS
- NOTE -
Conplete appropriate sections of data sheets VI.1 {} and VI.3 as these instructions are followed. A. Determination of Objections during Destressing
- 1. From the initial Prestressing Report or previous Surveillance Tests determine the initial value to be clotted on the Force-Time Curve.
(a) For tendens not previously part of any surveillance test or repair. Find the point of entry into the Force-Time Curve as folleve. From the Prestressin5 Report, Appendix A, column (e) determine D", the vire stress at seating. Subtract off the following losses which are expected to occur in the ('} first 4 days (.01 yrs)

Convert O'h, the wire stress after four days to F4 , force per vire after four days F4 = D'4 x k ,= g 0.04909CTh (A ,= Area of vire = .0h909 in ) j Enter this value (.01 yrs , F )4into the Force-Time Curve. (data i i sheet VI.3) I lO . 1 - l L
e DATA SHEET VI.1 INSTF.UCTIONS
, (b) For tendons previous part of a surveillance or repair,
(} vhere tendon has been stressed since its initial stressing. Determine, O', the seating stress at restressing. Convert the- seating stress,CF , to force per vire, F, at the ti=e of restressing. F = O'x Ag = 0.0h909 [7' ( AW = Area of Wire =.0h909 in2) Determine the ti=e between initial stressing and the restres-sing. Plot the values of force and time calculated above, onto the Force-Time Curve (Data Sheet VI.3)
- 2. From the point entered into the Force T'=e Curve, lay a line parallel to the one shown for the predicted minitum effective prestress. The intersection of this line with the time ordinate for the surveillance vill give FLE, the e ected Lift-off Force /
{} vire. Conve rt F LE, the expected lif t off force per vire to, FL , the expected lift off force, by multiplying by the number of
. e'ffective wires in the tendon. (See Appendix A, column (g)
~
of Prestressing report or previous surveillance tests). , FL=FLE x Ne ' (Ne = # effective wires)

(a) Maxi =um Effective Prestress (b) Predicted mini =um effective prestress for this surveillance (c) Absolute mini =um effective prestrees
- k. (a) The 805 =Inimum ulti= ate strength (0.8f's) of the tendon is 9.k3 kips per wire.
(b) The initial elongation =easurecent is p'erfor=ed at a force of 1 kip per vire.
. l
5 Convert the forces per vire in step: 3 and h above to total forces by multiplying by I'e, the number of effective vires. O V 6. From the calibration curyes for the stressing ra=s, to b,e used for the surveillance of this tendon determine the* hy-draulic pressures corresponding to the forces determined in step 5 above. . B. Acceptability Of Lift-Off
- 1. If both average hydraulic pressures obtained during deter-
, mination of lift-off have the following relationship to the hydraulic pressures detemined in step A.5 of these instructions, they may be considered acceptable and steps 3.2 thru B.7
*need not be completed untillater. If the below conditions are not satisfied, steps 3.2 thru 3 7,=ust be co pleted i .
imediately to verify acceptable liftwff forces. Steps B.2 thru B.T vill be completed for all tendens.
- If both of the average hydraulic (a) below the maxieum effec-
- tive prestress pressures (for vertical tendons and above the minitu= effec-
~
(b) only one is obtained) are within tive prestress and the limits described tendon lift- (c) above the predicted mini-i cum effective prestress off may be considered acceptable. ) for this surveillance.
- 2. Determine the lift-off forces as shown belov (a) For horizontal 'and dome tendons. Convert the average .
lift-off hydraulic pressure r.easured on each end of the tendon to corresponding forces by use of the stressing ram calibration curves. Average the two forces to deter-mine the lift-off force. bm (b) For vertical tendons since stressing is perfor ed f a only the upper end, lift-off is deter =ined by directly
~
convertin 5 the average hydraulic pressure at lift-off to force by using the stressing ram calibration curves. 3 Convert the lift-off force to force per vire at lift off.
'Ihis is done by dividing the lift off force determined. in step 2 above by the number of effective wires in the tendon.
- h. On the Force-Time curve (Dats sheet VI.3) plot the value of force per vire obtained in step 3 above, with the time ordinate corres;cnding to the time of the surveillance.
- 5. From the ,,oint plotted in section A of these instructions draw a line through the point plotted in step E.h above and extrapolate to h0 years.
- 6. If this line intersects the upper or icver bounds of the Force-Time curve (i.e. prediction exceeds the maximum effective prestress or goes .belev. the einicus effective
(~) . V prestress) or if,the point plotted in step B.h above fall below the icver bound of the force time curve the Surveillance Test Engineer vill detemine whether tendon degradation exists or whether this condition indicates a need for further surveillance ' 5
. in the future. If tendon degradation is indicated the two
~

(~N From page 5.hk of FSAR, Ear.. lift off force of 775 kips. Since'it is U possible that a 15 =casurement error could be introduced, *the maximum force should be 782.75 h'd p. For a 90 vire tendon this gives: _782.75 Kips per wire = 8.697 Kip /vire 90
- 2. Lower bound is based on the tendon with the lowest net ef fective force after h0 years as given in Appendix A of the Prestressing Report' . .

- 3. Predicted =inimen effective stress line is based on the following:
- 1. For verticals - 40 yr. loss is 2194 Ksi (FSAR P. 5 h3)
O d 2. For Dones - h0 yr. loss is 22.22 Ksi (FSAR P. 5 43) 3 For Hoops - h0 yr. loss is 25.15 Ksi (FSAR P. 5 h3) 70% of this loss occurs in the first year (Eechtel Civil) _ k'e now have two points to plot the curve. Based on the extrapolation of this line, the intercepts for 0.01 years can be found, and thus the losses' for the first 0.01 yrs can be found.
- 1. The sssunption has been =ade that all losses are equal for all tendcas in the first 0.01 years. .' -
- 2. The line as plotted is a straight line, ie, losses, are a fixed exponential rate. It is possible that the initial losses after seating
'a'r e lost at a greater exponential rate than at any other time. The error introducted by this factor, however, should not be significant
(~#) since the tine interval after ti=e sero is s=all. I

- 1. Find Elongation: .
nongation is the extension between an applied force of 1 kip /vire to 0.8f's. Distance is =casured between the bearing plate and bearing force of the stressing vasher. Total Elongation is the sum of the net elongations at each end. Elongation = Elongation @ 0.8f's - Hongation 81 kip /vire Total = ElonEation (End 1) + ElonEation (End 2). Compare with initial Elongations indicated in Appendix D of the Prestressin6 Report. If any significant deviation from the initial value -is indicated, in addition to a decrease in lift-off forces sore reliable infor-cation may be gained as to tendon condition. Tnere are no acceptance criteria for Elongation, but data vill be a part of the evaluation by the Surveillance Test Engineer. , END (1) E!!D (2) EI?D (1) E!iD (2) E?:D 1 EIID 2 TOTAL - 1 kip 1 kip 0.8f's 0.8f's ?et I!et ' DESTRESS l .

All infor=ation given is believed true, and, reflects pest experience. ?io sketches are to scale and since mo st are dra*.rn from r.e=ory, may contain inaccuracies.

Comuni cations
- During all qtressinC, destressing, vire removal and greasing operations U) it is extrenely critical that exclusive co=unications be established between each tendon end. Each end should have two headsets , one for each stressing ran operator and one for each of the engineers / technicians who are determine lift-off etc. Tne best method for connunication is a locally strung sound-povered system. Radio co==unication should also be availeble a
for use in times of energency ( for control room personnel to notify the tendon crevs of i=pending steen releases etc.'or to allov vorhers on stranded sky - climbers'to si 6nal for assistance). - -
~
STRESSING RO'.S TO 3E USED *
- 1. For horizontal tendons inside the auxiliary b'uilding the short ran vill allow naximum utilization .of the space available.
Hung as shown below: f') v - s _ O Ecan supported fron anchor l r, . bolts by end achorages. . cui es I - l - Fm 8
= , Horizontal, Inside Auxiliary Building r '
pJ - l . . i _ RAM
.j .
l
- 2. For horizontals outside containment a long or short ra= tay be used.
, For hori:entals , close to ground level the ram can be hung from the sky-A climber instead of trying to use a beam (as shova above for the inside -
ends).
~'
- 3. A long rom is required to stress a tendon which has an externally threaded stressing vasher because of the donut adapter, Since the d done tendons have externally threaded vashers on one end and internally threaded .tashers on tha other, and identification hf which end is wh.'.ch can only be made by examination, a long ram should be used on each end. The adapter should be available for use on*each end
- h. The verticals are stressed from the upper end only,so a very long ram vill be needed (2h stroke) to handle the cc plete elongation-If a 24" ram is not available, it may require that destressing be conpleted in two steps. Re=ove some of the shics , depressurice the ram, -
readjust the pull rod collar and then repressurice to allow removal of the remaining shins. I
- 5. A cra' n e vill be required to lift the stressing ra-.s. and purps onto the containment done, This is a lift of abou) 125 '

the ram the " donut" adapter must be screved into the stressing vasher. It is important that this goes in far enou6h to allow the threads to withstand the forces during stressing, but not so far that it can contact the shins and transmit bearing loads which vill cause binding and prevent its removal at completio'n of stressing.
