s KOUOm w3CLEI.st PL ANT SEQUOYAH NUCLEAR PLANT COMPUTEDM f DME (l-7-6 FOUNDATION INVESTIGATION EVALUATION CA M ERCW PUMPING STATION ROADWAY ACCESS CELLS A AND B 1.0 PURPOSE i

The purpoco of this investigation was to re-confirm the adequacy of the concreto, concrote/ rock interfaco and foundation rock for roadway access cells A and B.

2.0 BACKGROUND

As a condition of restart for the Sequoyah Nucicar Plant, TVA was requested by NRC to perform an in-depth assessment of the structural adequacy of the Essential Raw Cooling Water (ERCW) Pumping Station foundation and Roadway Access Cells (A02 860629 010).

TVA submitted to NRC on October 20, 1988, an evaluation of the ERCW foundation and roadway access colls performed by Bechtel North American Power Company (BNA)

(L44 881020 800)..

BNA'o ovaluation concludod that tne ERCW foundation and roadway ace'eas cells are structurally adequate and will function as intended under their design loada.

However, a limited exploration program for the foundationo was proposed oy BNA/TVA to augment the ava11ablo data usod in ovaluating the foundations (L44 881228 807).

This exploration holes through the concroto andprogram included drilling four into rock in roadway accesa collo A and B, evaluating the coro, and back-filling the holos with cement grout (SMI-0-400-6/DCN-M01322A).

3.0 INVESTIGATION 3.1 General The investigation consisted of drilling three-inch-diamator' core holen located on a l'ino peEpen'dicular to the contor line of the roadway and three foot from the edge of access cella A and B (Figbre 3-1).'

All holes were drilled vertically with the exception of the hole on the couth side of call B, which was drilled at an angle of 4.5* from vertical.

The angle hole was drilled to check the operation of the inclinomotor and to toct the accuracy oi angle drilling, which will be nooded when the holes in the pumping atation are drilled.

To clear embedded conduits, the angle hole wac atarted 1.5. foot from tho edge of the cell and angled toward the contor of the coll.

The hole intersected the top of rock approximately 8 foot from tho south edge of cell B.

In ordor to provent the accidental an olectric drill equipped with a ground faultpanotration of pipon or condulto, interruption devico waa used for the first 9 to 10 foot.

Each hole wau completed utilicing a wirolino coro drill to a minimum depth of 15 foot below the concretc/ rock interface.

Thia ovaluation also utilicod two vertical core holes drilled in 1977 at the contor of each coil (Figure 3-1; Attachments 3 and 6).

'_ peg ////t//}

A drill log record was maintained as each hole was drilled.

Each drilled section of core, or ' pull," was recorded; and tne percentage of core recovery (Tables 3-1 and 3-2), any loss or gain of drill water, and any unexpected conditions encountered during drilling were noted.

The core was placed in divided boxes in 5-foot lengths 1or later detail study.

After the completion of each hole, NE representatives logged the core and noted the condition of the concrete, concrete / rock interface and rock (Attachments 1 through 4).

A photograph was taken of each box of core for a visual record (Attachments 5 and 6).

Because of the steep d1p of the bedding and the fissile nature of the shalo, the rock coro has the tendency to fall apart when handled and placed in the core boxes.

To demonstrate that the roeg was intact during drilling, a video tape was made of the rock core for holes ACA-2 and ACB-2 as the core was removed from the core carrel and placed in the core boxes (T' apes are stored in the SCN vault).

Where the core indicated unexpected conditions or no coro was recovered, a bore-hole TV camera was used to further evaluate tnose A video tape was mado of these sones for future rotorenco cones.

(Tapec are stored in the SQN vault).

Upon completion of data collection and evaluation, the holec were back-filled with coment grout and the volume of grout recorood.

4.1 Cell A 4.1.1 Concrete The concrote for cell A is continuous over its ontiro deptn in all three core holes.

However a near-vertical crack is present in hole ACA-2 from 16.2 ft to 19.0 ft and 21.3 ft to 21.6 ft bolew tne surface.

This very tight crack is radial in direction anc.

wnen viewod with the boro-holo TV camera, can be traced where t cut through the coarse aggregato but is difficult to follow in the

~'

coment matrix.

The crack is likely the result of thermal e n rinica no and would not offect the structural integrity of the concreto..

Additionally in holo ACA-2, 0.2-foot and 0.1-foot thick :omont-filled coams that did not contain aggregato woro located 34.4 foot and 39.4 foot from the top, respectively.

The concrote/ rock interfaco as observed in the core samplos contained weathered rock at the contact in at least two of the three holos.

In holo ACA-2 the coro was not recovered for 0.8 of a foot at the contact.

However, upon viewing with the TV camera, this sono was found to contain fractured and fissilo shalo.

Based upon the core and viewing with the TV camera, the rock surface was Judged to had been adequately cleaned before the placement of concreto.

4.1.3 Rock The rock beneath cell A is steeply dipping, interbedded 11montone and shale.

The shale is somewhat fissile, and where slightly weathered partings occur in the shale and alternating hard and softer layers of rock exist, core rocovery is extremely difficult resulting in core loss conos.

When the side of holes ACA-1 and ACA-2 are viewed with a bore-hole TV camera, however, rock is visible for the length of the holes.

The rock core observed from coll A is consistent with that.proviously encountered at this sito and is consistent with the original calculation of rock modulus ana boaring capacity (B41 871208 001).

4.1.4 Grouting Holes ACA-1 and ACA-2 woro back-filled with grout based on the following information.

The concrete was continuous and had 100%

core recovery.

Although the rock had areas of slightly weathered rock and conos of core loss, the bore-holo TV camera showed that competent rock is continuous for the entiro length of those holes.

Back-filling was accomplished in two stages.

The rock tono, or first stago, was grouted followed by the concreto cono, or s,ocond atago.

The theoretical volume of holos ACA-1 and ACA-2 is 4 ft' cach and' represents tho volume of the cylinder drilled without considoring any open joints and partings in the rock cone.

In a S-Inen-diamotor hole, 20 linear foot equal one cubic foot.

For holo ACA-1 the first stage or rock sone was back-filloc with ono ft* of crout which f111od the bottom 13 feet of the holo.

The accond stago of 72 foot required 4 ft*.

Tho total back-fill for this holo was approximately 5 ft 8 of 0.75:1 coment grout.

Holo ACA-2 required a total of 4.75 ft' of 0.75:1 coment grout to ~~

onck-fill.

The firct stago or rock cono required 1.25 ft* and filled 20 toot of the holo.

The cocond staqo or concrote ao.ction was back-filled with 3.5 ft* and wac 62 f oot in length.

The additional one it* of grout requi, rod to fill this hole reculted from the inability to accurately measuro'the oxact volumo placed in the hole.

Thia inaccuracy in attributed to grout romaaning in the mixor and hoses and filling any partings and open joints that oxist in the rock sono.

tight contact in holes ACB-1 and ACB-2, and 0.2-foot of mud or silt lin the center hole.

Based upon the core and viewing with a bore-hole TV camera, the rock surface was determined to had been adequately cleaned before the placement of concrete.

4.2.3 Rock The-rock beneath cell B is steeply dipping interbedded limestono and

[

shale.

The shale is somewhat fissile, and where slightly weathered partings occur in the shale and, alternating hardor and softer layers of rock exist, core recovery is' extremely difficult resulting in core loss mones.

When the side of holes ACB-1 and ACB-2 are viewed with a TV camera, however, rock is visible over the length of the hole.

Specifically, hole ACB-2 has a 3.7-foot core loso cone i

approximately-four to eight feet below the top of rock.

Observation of thia =one with the TV camera indicated that the rock 13 nearly vertical and fractured, small pieces have fallen into the nole, and the zone'was sightly oversized during drilling, but rock is prosent throughout the. cone.

The rock core observed from cell B is.

conulstent with that previously encountered at this site and is consistent-with-the original calculation of rock modulus and bearing capacity.(B41 871200 001).

4.2.4. Grouting g

Holes ACB-1 and ACB-2 were back-filled with grout based on the i

following information.

The concreto was continuous and had 100%

core recovery.

Although the rock had areas of slightly weathered rock'and cones of core loss, the bore-hole TV camera showed that

- compotent rock is continuous for the entire length of these nolos.

Back-filling was accomplished in two stages.

The rock cone, or first stage, was grouted followod by the concreto sono, or seconc stage.

The theoretical-volume of holes ACB-1 and ACB-2 la 4 ft' each anc

filled the bottom 8 feet of the hole.

A second ctags in tho rock

one accepted-3.75 fts and filled 41 feet of the nole.

The Jrd stage,-or upper concrete section, required 2 ft8 and was 34 feet in j

length.

P The additional grout for thin hole apparently coeped into tho-l fractured rock in the.3.7-foot core loss cone described in section

'i 4.2.3.

This is demonstrated by the elevation of the grout after i

back-filling the first stage in the rock zone.

e l'

5.0' CONCLUSION m

The concreto in roadway access cella A and b le sound with no i

indication of weak or segregated concrete.

The observed condition of the concrete / rock interface for the six holes indicate that the cells.were adequately cleaned prior to concroto placement.

The rock observed in the cores as consistent with that previously encountered t-at the site and is consistent with the original calculation of: rock modulus and bearing capacity.

The partinga and open aointa i

encountered in the rock are inconsequential.

Grout takes are well within the generally acceptable limits for back-filling holce that can be expected to be slightly overcised during drilling in aream of slightly-weathorod rock.

Thorefore, TVA concludes.that these investigationu re-cenfiro tne structural integrity of the roadway acceso cells and that theco l

cella will perform their intended function uncor all coulgn conditiona and no aaditional investigation is noconsary or requirbd.
