6.4 Stresses due to Rigid and Flexible A Sleeves

==

Description:==

In post-tensioned systems, sleeves are installed at the same time as reinforcing bars to be used later as conduits for the post-tensioning tendons. Note that they can alternately be called "sleeves", "conduits", or "sheaths". We are using the former in this analysis.

Different types of tendon sleeves are used in Nuclear Power Plant containment structures. Rigid sleeves are used in straight sections while flexible sleeves must be used to go around containment penetrations.

6.4a: Vibration of rigid sleeves The hydro-blasting high-pressure water jets can induce stresses on the sleeves and concrete. Additionally, hydro-blasting can induce vibration of the exposed rigid sleeves leading to cracking in the adjacent concrete. In particular, thick-wall rigid sleeves are more prone to vibration than thin-walled flexible sleeves that would typically simply crush under the impact of the water pressure.

6.4b: No tensile transfer at the smooth concrete / rigid sleeve interface Rigid sleeves have a smooth surface that can lead to very low concrete/sleeve bonding and virtually no tensile carrying capability across the bond.

Data to be collected and Analyzed:

1. Review the types of tendon sleeves that are allowed in the Design Basis Document (FM6.4 Exhibit 1) and in the Work Order (FM6.4 Exhibit 2);
2. Examine the sleeves used at CR3 (FM 6.4 Exhibit 3, FM6.4 Exhibit 4, and FM6.4 Exhibit 5);
3. Calculate vibration due to possible excitation of rigid sleeves by hydro-blasting water jets (FM 6.4 Exhibit 6);

2/6/10 - Page 1 of 3 Draft 1

4. Examine the effect of no tensile transfer capability across the concrete/sleeve interface.

Verified Supporting Evidence:

a. The very smooth surface and lack of mechanical bonding at the sleeve / concrete interface leads to virtually no tensile transfer at the concrete / sleeve interface; Verified Refuting Evidence:
a. Using different types of sleeves is allowed by the Design Basis Document (FM 6.4 Exhibit 1 and FM6.4 Exhibit 2);
b. Using smooth rigid sleeves is standard in other plants that have not experienced delaminations;
c. Vibration analysis shows that the hydro-blasting water jets on the exposed sleeves do not generate stresses large enough to create the delamination (FM 6.4 Exhibit 6);

Discussion:

Examination of the vertical tendon sleeves demonstrates a mixed use of flexible and rigid sleeves in the CR3 containment structure (FM 6.4 Exhibit 3 and FM 6.4 Exhibit 5). Photographs of the containment show rigid tendon sleeves for hoop and vertical tendons in the area of the SGR opening (FM 6.4 Exhibit 4).

Concrete pieces recovered after the demolition job show a very smooth interface between the concrete and the sleeve surface (FM 6.4 Exhibit 7);

Although the impulse generated by the high-pressure water on the concrete structure is not sufficient to generate the delamination through vibration, it is possible that the added energy was instrumental to propagating the crack beyond its original location. Because there is a layer of material where the radial tensile stresses are positive (albeit small on average) (see FM 1.2), once the crack is generated, it is "live" and can propagate until reaching a region of zero or compressive radial stress. This is the case near the buttresses and below the ring girder where the steel reinforcement can carry the tensile stresses.

2/6/10 - Page 2 of 3 Draft 1

The mixed use of flexible and rigid smooth tendon sleeves is standard in the industry and in the case at most plants in the USA.

Because virtually no tensile load can be carried across the sleeve / concrete interface, the sleeves act like defects in the structure. In the various models, this is taken into account by having no cohesion or tensile stress carrying capacity between the sleeves and the concrete. The sleeves become potential initiators of cracks, especially as a very large traction is applied on one (but not the other) side of the sleeve.

This potential for crack nucleation is confirmed in the FEM analysis. It is captured at the discontinuity that represents each tendon location where traction is applied on the interior face only.

The analogy is that of tearing paper along pre-drilled aligned holes.

==

Conclusions:==

6.4a: Hydro-blasting induced resonant vibration in the rigid sleeves did not cause the delamination. It may have contributed to the crack propagation.

6.4b: Poor bonding at the concrete / sleeve interface leads to considering the sleeves as 5.25" cracked regions in the structure. This is however an as-designed feature that was considered when the plant was first designed and constructed. It did contribute to the delamination by weakening the plane of the hoop tendons.

The WORK shall be as outlined herein and as shown on the Drawings and shall include, but not necessarily be limited to, the following:

1. Furnishing all materials required for the conduit, including temporary end caps, and protection required during transportation and delivery.
2. Delivering of conduit to the job site.
3. Furnish all necessary shop drawings for the related WORK.

3:02 General 3:02.1 The conduit system shall consist of Rigid, Flexible, and Schedule 40 conduit as indicated on the accompanying Florida Power Corporation drawings. The requirements under Items 3:02 through 3;05 and 3:09 of this Requirement Outline shall apply to the three types of conduit.

Specific requirements for Rigid, Flexible, and Schedule 40 conduit are Indicated in Item 3:06, 3:07 and 3:08 respectively.

3:02.2 The conduit shall be delivered to the site, complete with temporary end caps, in a clean condition, i.e., both surfaces free of debris and deleterious substances. The CONTRACTOR shall submit details of the proposed temporary end caps to the OWNER and ENGINEER for approval.

3:02.3 Upon delivery to the site, the conduit shall be inspected by the OWNER for detrimental splits, cuts, aud dents. In order to determine if a dent is detrimental, a wooden pig of 4-3/4 inches diameter shall be pulled through the conduit. Should a dent or dents restrict the passage of the pig, the conduit will be rejected and shall be re-placed at no additional cost to the OWNER. Should the conduit be delivered with any splits or cuts which completely penetrate the wall of the conduit, it shall be rejected and replaced at no addi-tional cost to the OWNER. Conduit delivered with splits and cuts which do not completely penetrate the wall may be accepted by the OWNER if it can be shown that the performance criteria called for in this Requirement Outline can be met and if the galvanizing coating can be repaired. Schedule 4O conduit with painted ends and couplings shall be inspected for damage to galvanized and painted surfaces. For this case any damage which cannot be satisfactorily A repaired by the OWNER will be rejected and replaced by the CONTRACT OR at no additional cost to the OWNER.
