for #12 and #8 AMG and thermocouple extension wires, or threaded type (225A5146) for #2 through #4/0 AMG wires. All connections are protected by Raychem Shrink Tubing (175A8230).

In addition, there is an IR5237 (262A7076) (3M Company) rigid epoxy cosmetic cover at the ends of all modules, which serves' no f unctional purpose. Failure of this epoxy will not adversely effect operation of the penetration.

Therefore, all 200 series penetrations employ the same materials and same basic configuration and can be considered similar for the purpose of equipment qualification.

3.0 INSTALLED VS. TESTED CONFIGURATION The electric penetration header plates are welded to the containment nozzles in a horizontal attitude. All but five (5) penetration header plates are mounted on the outside wall of the primary containment (Attachment 1).

Junction boxes are installed on both ends of all penetrations and enclose the penetration modules.

In the test configuration, the module is installed in a vertical attitude as shown in Figure 2 No junction box protection is provided. In the test configurations, the modules, wire, and connections are directly exposed to the saturated steam environment.

The test configuration is, therefore, more severe than the installed configuration since it has no protection by the junction box and is exposed to direct saturated steam conditions (see Section 4.1).

In addition, the autoclave is not a heat sink like the containment wall, therefore allowing the penetration to be heated up somewhat more rapidly than in the actual installation.

4.0 ENVIRONMENTAL QUALIFICATION 4.1 Design Basis Event The postulated profile of environmental conditions for the LOCA event for shoreham is as follows for inside the drywell:

The postulated and test temperature profiles are shown together for comparison on Figure 3.

For the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of the test, the test profile envelopes the shoreham postulated profile in pressure, duration, and temperature.

During the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months of the test, simultaneous voltage (250 VAC) and current (2.5 amps) were continuously applied to both the #12 AWG and thermocouple modules (Test Report, pages 32 and 33, Tests #1.and 02) which represent all low voltage modules (see section 2.0).

The test setup is as shown in Figure 2 The penetration modules remained helium leak tight to less than 1 x 10-6 ee He/sec. (Test Report, page 34) which satisfies the IEEE Standard 317-1976 guideline of 1 x 10-2 cc N /sec.

2 The over-testing described above is adequate to extend the qualification for both pressure integrity and operability over the remaining period to cover 180 days (see sections 4.2 and 4.3 below).

In addition, the dielectric strength test of the #12 and thermocouple modules is adequate to qualify the remaining modules as discussed in section 4.6, and the heating eff ects of 2

the thermocouple module (I R) are in excess of plant applications as discussed in section 4.5.

4.2 Pressure Integrity The 200 series low voltage containment penetration is designed and constructed to maintain containment pressure boundary integrity during all plant postulated normal and accident environmental conditions.

The 200 series penetration is mechanically structured to prevent " blow out" of the modules and a subsequent loss of containment integrity. As shown in Figure 1, the internal components rest against a lip on each side of the steel penetration housing to prevent " blow out" initiated from either direction.

Environmental qualification testing (Test Report, page 32, Tests #1 and #2) has demonstrated the ability of the penetration modules to withstand extreme external pressure (103 psig) at elevated temperatures (340*F peak) without loss of any structural integrity.

The modules were satisf actorily tested to demonstrate pressure integrity during postulated post-LOCA pressure and temperature conditions subsequent to sequential testing for thermal cycle stress aging and radiation. External test pressures ranged from 20 to 103 psig with corresponding temperatures of 210*F to 340*F.

The ability of the penetrations to maintain containment integrity given a postulated peak accident pressure of 48 psig.

Scotchkote Coating This coating is applied to the conductors to maintain electrical resistance between them.

while this coating is no longer manufactured, its properties are considered similiar to scotchcast 5230 (Attachment 4).

Using this data in the Arrhenius equation results in an activation energy of 1.49eV.

h.

ERR-300 Epoxy This epoxy forms the primary seal for these penetration modules. While its activation energy is not currently known, a review of the activation energies typical of epoxies which exhibit similar properties (e.g., 2.04eV for GE's N229) indicates that the limiting activation energy for the other materials contained within this assembly should be much lower, and therefore bounding for this epoxy.

Therefore, the limiting activation energy for the critical materials contained within this device, specifically EPR, XLPE, Raychem shrink tubing, Scotchkote and EMR 300, is considered to be the 1.23 eV for XLPE.

It should be noted that the activation energies listed above are for materials exposed directly to air.

Due to the nature of the construction of these penetrations, the EMR 300 epoxy, Scotchkote, and Raychem shrink tubing are either sealed from any gaseous environment or will normally be exposed to nitrogen only. Since it is generally considered that oxidation is one of the dominant mechanisms for thermal degradation (Reference 4), the activation energies presented here are considered conservative due to the lack of an oxidizing atmosphere.

4.3.2 Extrapolation of the Test Profile Since thermal degradation is a cumulative process, the test profile discussed in Section 4.1 above can be regrouped for convenience as follows:

Power assemblies utilising 480 VAC and requiring operability for 70 minutes are qualified by the power assembly LOCA Test #1 (Test asport, pages 32 and 33), wherein the conductors were energized at 500 VAC and carrying current for 75 minutes.

Power assemblies utilizing 480 VAC and requiring operability for 180 days require special consideration.

The test conducted on the thermocouple module provided a voltage stress of 250 VDC across a minimum dielectric thickness of.0555= (163C1790) or 4.5 volts / mil.

The #2 AMG modules which carry the load for the 480V circuits require a dielectric strength of 480V across 0.077" (163C1790) or 6.2 volts / mil. Although the test value did not exceed the required value, these are exceedingly low dielectric stresses.

Typical dielectric strength for epoxy resins varies from 425 to 2000 volts per mil (Reference 3) depending upon dielectric thickness.

At LOC;. hveratures, dielectric strength will be approximately 200 volai/ mil (Reference 5), well above the required 6.2 volts / mil.

the required dielectric strength is very small compared to the Because above epoxy resin dielectric strength, the assemblies using 480 VAC will function as required.

5.0 SURVEILIANCE PROGRAM A maintenance and surveillance program will be performed to monitor penetration integrity.

Periodicity will coincide with required leakage tests per Appendix J to 10 CFR 50 (Type B tests).

A maintenance and surveillance program will also be perf ormed to monitor the electrical characteristics of these penetrations.

In test #1, a dummy module blew out of the autoclave and caused a severe energy release which bent the uninsulated wire connections of the power modules to short to the wall of the autoclave when high voltage was applied.

2 In test #3, 2 of the 10 cables of the #2 AWG modules shorted t the autoclave wall due to steam buildup within the autoclaveo Removal of those 2 cables reduced the sample size to 40%

In test #1, the module which blew out was an old one (not 200 Series) which was used as a plug to fill the 7th hole in th headplate.

RECORD OF CONVERSATION C Meyer (3-M) x Telephone Meeting Other r

TO. Curt Meyer FROM:

Steve Pauly ATE 11/29/82 Y

3-M Product Information Center 612-733-6739 COMPANY:

PHONE NO.:

Scotchkote Resin 2006

SUBJECT:

Summary of Conversation:

Mr. Meyer stated that 3-M no longer produces this coating. However, from the description of the properties listed on G.E. Drawing No. 262A6669, this resin is probably most similar to Scotchcast 5230. In particular, the specific gravity for Scotchcast 5230 of 1.5 is close to the specific r

gravity of 1.62 for Scotchkote 2006. h e lower specific gravity of the Scotchcast 5230 would probably make heat aging data for Scotchkote 2006 conservative. He Scotchcast 5230 was exposed to the following condition to achieve 504 breakdown in dielectric strength:

2000 hrs at 180 C 7500 hrs at 1620C 400 hrs at 2000C (see attached Arrhenius plot) 5 m e e
