1.0 PURPOSE

.The purpose of this engineering evaluation is to document the resolution of an Employees Legal Project concern regarding submerged electrical cables in underground electrical manway enclosures at Seabrook Station. This engineering evaluation will address all safety related manway electrical enclosures and non safety related manway enclosures as required.

2.0 BACKGROUND

In the June 1986 time period, several site electrical cable ducts were found to have water in manway enclosures and were de-watered during the final closeout in preparation for construction turnover to the plant staff.

The initial design of the safety related manway enclosures provided several water proofing membranes to maintain enclosure dryness without reliance on a pumping system. Each manway enclosure included a small sump area to provide a low point for de-watering and complete pump down to the floor level when de-watering was necessary.

On March 1, 1990 the Employees' Legal Project submitted a letter to NRC Chairman Carr that expressed the concerns of a former Seabrook Station employee regarding the effect of cables submerged in water in the manway enclosures on safe plant operation. The letter is included as Attachment 1. The concerns expressed in that letter form a partial basis for the discussion in this engineering evaluation.

l 3.0 DISCUssIog To develop a detailed response to the ELP employt.e concern, NHY initiated a 1

thorough evaluation program of the installed electrical cables and cable supports '

in the electrica) manway enclosures. The program includes identifying the safety related and non safety related electrical manways, and an inspection program for the safety related electrical manway enclosures that can be extended to the non safety related electrical manway enclosures, if necessary. The inspection includes a visual inspection by an electrical designer and a structural engineer.

The above discussion accounts for one hundred eleven (111) electrical manway f enclosures at Seabrook Station. Of'these, twenty-two (22) Unit I safety related electrical manway enclosures, six-(6) Unit 2 safety reinted electrical manway !

enclosures and the meteorological (met) tower manway enclosure were inspected to determine the extent of cable submergence. i 3.2 Inspection Pronram for Electrical Manway Enclosures

'i Upon reviewing the ELP employee concern, NHY initiated an inspection program l 1

for each of the twenty-two (22) safety related electrical manway enclosures for. )

I Seabrook Unit 1, six (6) safety related electrical.manway enclosures for Unit 2 i

-)

and the met tower electrical manway enclosure. The electrical manway enclosures I were inspected for each of the following attributes:

o The as found condition of the manway cover caulking seal.

o The presence of the water in the manway enclosure and depth, if-applicable, o The water in each manway enclosure was analyzed to determine if there ;

)

are chrmical constituants that would ba detrimsntal=to ths' cable material. Chemical compounds tha't are detrimental to the cable a

material were identified by Wyle Laboratories-as identified in-

{

i I' Attachment 2. Two assumptions form the basis 1 for sampling for; !

l detrimental substances:

J Assumption #1: Compounds on the Wyle list are generally immiscible with' I water. l Assumption #2: The failure Mode for the cables.being'affected'by the ;

solvents on the list would'be immersion'in high '

i concentrations of the compounds. 4

-i

The following chemical analysis program is applied to each water' sample j

.i i

. t from the manway enclosures by the NHY Chemistry-Staff:

i 1. pH, salinity, visual oil / grease screening.

4 2. Total Organic Carbon (TOC) Analysis to the ppm level, I

j 3. Flash point analysis for volatile organics.

In addition, four (4) representative samples were sent to an off-site i

j lab for GC/ Mass Spectroscopy analysis of volatiles. j i

] If any slime substance or white deposits were observed, samples were '

) collected and analyzed, o Polaroid photographs were taken of the as-found cable condition and of'

the support bases after de-watering.

o The manway_ enclosures were de-watered.

4 i'

o

} A visual inspection of the electrical cables in each manway vault was '

performed by an electrical designer. As a minimum, the cables were .;

inspected for the presence of cuts, abrasions, kinking, cable splices, l :

cable repairs, and bend radius. I o A structural engineer inspected the cable support system including the column bases that may have been submerged.

i o

The enclosure was inspected for determining possible water inleakage I

4

paths.

~

o Sketches were prepared to identify the extent of cable submergence and the possible water inleakage paths.

The following discussion describes the basis for selecting the above attributes.

The as-found condition of the manway cover caulking seal provides some insight to potential leak paths. The depth of water provides information as to the extent of submergence in the manway enclosures. As experience was gained during the inspection process, the distance from the enclosure floor to the lowest cable was determined. Water samples assist in determining if the inleakage is seawater as was mentioned in the ELP employee concern and also assists in determining the chemical environment for the cable and support system. Since slime and white deposits were mentioned in the ELP employee concern, any evidence of these were examined. The photographs provide a record for future reference. The de-watering provides access for the visual inspections of the cable and the supports. The visual inspections of the cables provide information on the as-found condition of the cables. The visual inspection of the supports provides information on the as-found condition of the supports. The inspection for possible inleakage paths provides evidence of fresh versus seawater intrusion and provides information for possible future corrective action.

3.3 Inspection Results Table 3.3-1 (Underground Manway Enclosure Inspection Summary) provides overall results from the ins,ections conducted on the twenty-two (22) Unit 1 safety related electrical manway enclosures, the six (6) Unit 2 electrical manway enclosures and the met tower manway enclosure, including water level, chemistry, electrical and structural attributes. l Table 3.3-2 (Water Chemistry). Table 3.3-3 (Electrical Inspection Summary) end Table 3.3-4 (Structural Inspection Summary) provide additional details.

Ths wster chemistry enslysis confirms that tha water in ths safoty rolatsd-

~

, c'ectrica' manway cnclosures is frosh watsr, not sacwater. For example..the-samples show chlorides on the order of 40-80 ppm, whereas seawater has a level of 19,000 ppm. The Seabrook town well supply is.approximately 15 ppm chlorides.

tione of the enclosures had any odor that would indicate the presence of solvents.

Jyle Labs identified compounds that would be detrimental to the cable matrrials utilized at Seabrook Station in IE applications. Wyle's review of the e

chemistry sample results confirm that the inleakage.is essentially pure water that is not detrimental to the cable materials.

Wyle Labs.had indicated in their report that the effect of organic compounds on the cable material is based on 100% concentrations. Results of the GC/ Mass Spectroscopy analysis performed by Resource-Analysts, Inc., included as L Attachmert 3, show no contaminates which are measurable except for Chloroform and Tetrahydcofuran which are present at such low levels that they pose no hazard to the cable material.

The inspection for the possible inleakage paths show that:the inleakage is from ground water at the enclosure top cover joint with the side walls. Sume-leakage was also evident at the manway access plugs. Water inleakage was also identified at the cable duct bank atry point.

To confirm the fur.ctional capability of installed cables, N"Y' performed an insulation tasistance test imegger test) on the SKv cable to service water pump 1-SV-P41D in accordance with NHY Procedu's MS0514.01. This cable had been submerged and was in a manway enclosure that had been de-watered. The results showed a cable resistance of 3400 megohms. The acceptance criteria for this I

cable is greater than 5 megohms.

In addition, one 480v non nuclear safety cable that was still' submerged in the temporary electrical duct system was meggered. This cable was the feeder )

)

cable from load center one to the sewage treatment plant settling basin control- '

panel. The results showed a cable resistance of greater than 500 megohms with an 6 '

l

acceptance' criteria of greater than 1 msgohm.

This further' demonstrates that the water surrounding the cable had no

' detrimental affect' on the electrical cables.

Plant records were examined fur the possibility of in-line cable splices.

In-line cable splices were not permitted at Seabrook Station.

3.4 Structural Review of Cable SucDorts Cable supports in manholes are qualified for seismic conditicus !n a generic calculation using the maximum possible cable loading.- A review of the qualification was performed to determine the impact of potential corrosion on the supports. The design has a minimum 1.12 factor of safety on derign allowables and a 4.5 factor of safety on failure. The limiting component of the design is the Hilti anchor bolts at the base of the support. A review of CASP indicates

hat the maximum loading on any support is 43% of that which was used in_the generic qualification. The act,ual loading combined with the safety factors in the original design yield a 2.62 factor of safety on design allowables and 10.53 factor of safety on failure on the anchorage design.

Frame Evaluation Cable supports are constructed with galvanized unistrut members and fittings; finishes which inhibit corrosion. Industry data on steel with these finishes give corrosion rates of 1 mil / year in seawater, an environment worse than the stagnant fresh water in the manholes. Applying a corrosion of 40 mils (1 millyr for 40 years) to the crossection of the thinnest unistrut member will reduce the capacity of the member by 38I. The conservative reduction in crossection would still allow for a 5.19 factor of safety on design allosesbles and 10.27 factor of safety on failure fer the unistrut.

Anchorane Evaluation Supports are anchored to the floor of the manhole with one-ha..f inch diameter Hilti Kwik bolte. Hilti Kwik bolt components are supplied with extensive corrosion protection in accordance with ASTM B633, SC1, Type III. The 7

alloy steal bolts and spring steel w:dges cro costsd with a 4 mil. zinc. coating and further protected with a chromate outer coating. Corrosion resistance of the i components is demonstrated by subjecting the components to a 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months salt spray.

Test acceptance is then confirmed by verifying the lack of corrosion of zinc or ;

base metal. Anchor bolts tbst had been submerged under water were checked with a q torque wrench to ensure that the minimum torque required to engage the anchot had n,c been reduced. The torque on the anchor bolt produces approximately 4,881 pounds tension on the bolt and components required to resist pullout. This -

yields a 5.33 factor of safety on tla maximum design tensile load on the bolt.

A rust colored coating was noted on the baJe connection and v7ttical members at the bottom ef the manholes during inspection. Subsequent to remceing the coating by light s raping, the galvanized finish was found senerally intact with- I minor pitting on the finish. The rust colored coating is attributed to oxidizing i of the metal through pinholes in the galvanizing. It was noted that for all the supports inspected there was no indication of measurable corrosion on the base metal. Table 3.3-4 summarizes the resalts of the inspections of the cable l

{

supports.

In summary, it is concluded that the presence of water in manholes does not adt ely affect the structural integrity of the caole support. The bases for this conclusion ares o Substantial conservatism in the support qualification o Corrosion resistant coatings on all support members o No significant defects on the supports inspected o In place torque check on Hilti anchor bolts 3.5 Myle Laboratories Report on Cable Oualification Wyle Laboratories performed an assessment of qualification of the cables used in potentially submerged applications in manways and vaults at Seabrook Station. Their assessment demonstrates that the Cross-linked Polyethylene and Ethylene Propylene insulated cables are qualified for the potentially submerged 8

s g - - , -

epplications. This demonstration is bassd on the following: f (1) These cables were procured as safety related cables, even'though used in safety and non-safety applications, '

(2) The application in manways and vaults is a mild environment and does not require specific qualification, (3) The cables are premium grade cables qualified _to Seabrook's worst case .

Harsh Eavironment, '

(4) The cables have proven, by test, their ability to. operate properly considering the effects of 40 years of aging, postulated radiation exposur(, and worst case Loss of Coolant Accident. I (5) After the LOCA exposure testing, each cable has further demonstrated proper operation in a submerged condition. >

(6) The cables were procured to stringent nuclear industry specifications, l which additionally required tests to verify insensitivity to moisture by Accelerated Moisture Absorption Tests, '

(7) The insensitivity to moisture has been demonstrated for greater than 40 years, using Arrhenius methodology, which has been accepted by the NRC when used to demonstrate long term exposure to Post Accident conditions, including submergence, (6) A review of industry experience has concluded, also, that these types of cables are insensitive to the postulated submergence and are therefore qualified for use in t'eae mild environments,

)

(9) Chemical compatibility to the fluids found in the vaults has been evaluated. No incompatible fluids were found.

The application of cables in manways and vaults outdcors at Seabrook Station is a mild environment. The areas in which these cables are installed does not change due to any postulated accident at Seabrook. Since the environment does not change, no speci9ic qualifications are required, nevertheless, the Wyle l

Laboratories Report provides the basis for demonstrating that these cables are 9

- - -. -.)

i qualified for this application.

The cables located in the manways and vaults are subjected to temperature i conditions conservatively estimated to be 20*C (68'F). Periodic submergence of portions of these cables is also postulated. -

The results of testing for Harsh Environmental Qualification and Accelerated Moisture Absorption Tests apply to the subject cables because these cables were procured as safety related cables, even though used in safety and non-safety applications.

For mild environment cables, no specific regulations exist which require demonstration of environmental qtalification, only conformance to specification and a maintenance program are required. Nevertheless, the Wyle Laboratories

Report provides the evidence, by test, that the cables are qualified for this environment. The conditions of the environment are enveloped by the harsh ,

environmental qualifiertica, which has demonstrated that the cables are qualified to the worst case environments and accidents at Seabrook Station.

The harsh environment qualification of these cables has been performed through IEEE-323 and 383 tests. These IFEE tests have been performed on each '

style of cable at Seabrook. The peak temperatures are generally in excess of 375'F pressures in excess of 60 psig, radiation levels in excess of 2E8 Rads, 40 years of aging, cheuical sprays and post accident submergence. The voluminous ,

results of these tests and associated files have been rigorously and thoroughly reviewed by Seabrook and consultant personnel and have previously been audited and found to be in compliance by the NRC.

The cables at Seabrook have been procured for all applications and provide optimum performance in electrical stability, tensile strength, flexibility, non-aging, abrasion resistance, dynamic cut through resistance, minimal heat distortion, r diation stability, self-extinguishing - non-propagating fire characteris.ics and Accelerated Water Absorption tests to verify insensitivity to long term e>?osure to moisture. The service requirements are (a) indoor, 10

7 i

gelvanizad steel, solid bottom and ledder-typa tray, (b) underground non-mitallic !

ducts,;(c) underground metallic ducts, (d) exposed, galvanized steel conduit and (e)~ wet and dry locations.

The Accelerated Water Absorption tests verify acceptable electrical properties after long duration tests while immersed at elevated temperatures with constant voltage potential applied. The test durations are a_ minimum of 14 days at 75'C to a maximum of 36 months at 90*C. The cables were shown t be, insensitive to moisture during the<* .ests and this insensitivity to moisture is shown to be equivalent to greater than 40 years at Seabrook. The equivalent moisture insensitivity time was calculated using Arri.enius eory, which has formed the basis of accelerated aging methodology used and approve d for harsh environmental qualification including submergence qualification inside containment. NRC requirements for aging evaluations for harsh environment qualification are codified in 10 CFR 50.49. REG Guide 1.89 and NUREG 0588.

Other nuclear plants have evaluated the effects of cable submergence on safety related cables. The 'Waterford 3 Cable Submergence Evaluation" was !

reviewed. This document shows that some of the same cable at Seabrook was evaluated for submerged use at Waterford, specifically Anaconda and Okonite

{

cable. The results of LOCA testing Accelerated Water Absorption tests, j Arrhenius based Equivalent Age calculation, industry experience with submerged '

i

! cable and an evaluation by Okonite conclude that these cables are also qualified for greater than 40 years in submerged conditions. The methodology used by Waterford and reviewed by the NRC is essentially the same as has.been used by >

Wyle to evaluate the cables at Seabrook as it relates to outdoor submergence. '

The conclusion is that these cables are qualified for the mild environment l

application for installation in outside, underground level manways and vaults at ,

T Seabrook Station which may be submerged for up to 40 years.

3.6 Surveillance Program >

3.6.1 Power Cable Surveillance Testing A megger test is performed on each power cable at a minimum of the intervals committed to in NHY's response (SBN-1107, dated June 13, 1986) to an NRC request 'l for additional information. These intervals are as follows:

Motors -

Feeder cables t' 'l safety and non-safety _related motors 50 HP and larger are tested every refueling.

Feeder ca'sles to all safety related motors smaller than 50 HP are tested every refueling.

Feeder cables to all non-safety related motors smaller than 50 HP l are tested every 5th' refueling. '

Unit Substations -

Poeder cables to all~ safety and non-safety related unit substations are tested every 3rd refueling. ,

Motor control Centers -

Feeder cables to all safety related Motor Control Centers (MCC) are tested every 3rd refueling.

Feeder cables to all non-safety related Motor Control Centers (MCC) are tested every 5th ,

refueling.

Miscellaneous -

Feeder cables to miscellaneous loads (except Motor Control Centers) fed from Unit Substations are tested at an interval not to exceed every 5th refueling.

The megger tests are conducted in accordance with site megger procedure MS0514.01. A megger consists of impressing a potential across the conductors of >

a cable and the scale reads out in Megohms of resistance. For cable testing the values are as follows:

12 1

i

. RATED VOLTS MEGGER TEST VOLTS MINIMUM RESISTANCE (IN MEG 0HMS) 4 125 VAC/VDC 500 1.0 480 VAC 1000 1.0 4160 VAC. 2500 5.0

~

The mogger, by virtue of detecting leakage, accurately indicates degradation in the form of leakage current through any weak spots in the esble insulation.

One stall leakage path in the insulation will drastically reduce the total megohm reading.

The megger testing results to date have generally been several hundred timcs higher than the minimum allowable and in many cases are higher than the instrument is capable of reading. The only relatively-low rae. dings are for cables connected to heating elements. These are still over twenty-five times the minimum allowable value. e i

Table 3.6-1 (Safety Related Cables In Manway Enclosures / Insulation Resistance Dat.*. Summary) provides the latest megger test results on cables in the manway enclosures.

3.6.2 Circuit and Grounding Detection Control circuits from 480v MCO (Motor Control Center) transformers are grounded circuits. Vital and important non-safety related motor control circuits have lamp indicators on the Main control Board showing the status of the. load (on/off, open/close). Should control power fail due to a degraded cable, both lamps would become deenergized alerting the operator.

Should insulation failure occur in an energized ungrounded or high resistance grounded wiring system such that only one line conductor faults to ground, the ground detection system will initiate an alarm in the Main Control i Room. On a Icw resistance grounded system loads are tripped upon detection of l

ground fault condition. If insulation failure occurs in an energized ungrounded or resistance grounded wiring system such that the fault is between two line conductors, the over current device will trip clearing the condition. Main Control Room alarms are provided on safety related systems and major non safety 13 l

l

. _ . . ._ __ _ ._ _ _ _ _J

rolcted systems to clart th3 op3rator. Eloctrical circuits which era ground:d will trip under both conditions as stated above. The system grounding and detection are further described as follows.

The 13,800 vel., system is a low resistance grounded system. Grounding resistors for limiting tie ground fault current to 600 amperes are locatad at the UAT and RAT transformers. Occurrence of a line to ground fault will cause the faulted portion of the system to be isolated by tripping appropriate circuit breakers. Inspection of the ground fault detector relays at the switchgear indicates the location of the fault. ,

The 4.16kV system is a high resistance grounded system. In addition, the diesel generator neutral is grounded through a single phase grounding transformer. In order to detect grounds, ground sensors have been provided on each motor circuit and load center feeder and each incoming line, including the diesel generator. Inputs from ground sensors and ground detection circuits are furnished to the station computer. The computer is programmed to recognize various combinations of inputs and to provide an alarm to alert the operator of the ground fault and its location. The grounding scheme utilized allows single gtound faults to be alarmed only, and the equipment to continue operation.

The 480 volt system is a high resistance grounded system. The grounding equipment is located at the 480 volt unit substations. This grounding i i

configuration allows the system to operate effectively as an ungrounded system, i.e., service is not interrupted in case of a single ground fault. Inputs from ground detection circuits are furnished to the station computer to alert the operator of the ground fault and its location.

The 120 volt ac vital system is a two wire ungrounded system with a ground detection scheme consisting of a ground detection panel. The ground detection panel associated with each vital instrumentatiot. hus r.ontains two voltmeters, each with a 0 to 150 V range. These meters are connected in series across the two supply lines of the system. Two voltmeter relays are incorporated together 14

4 I

with the voltmsters in the p:nal. The relays are used to provids the bus ground -)

I alarm to the station computer. Ammeters are also provided on the Main Control j

l Board to alert the control room operator of a groucied condition on the associated bus. !

1 TLe 125VDC vital system is a two wire ungrouaded system with' ground

detection. The ground detection consists of a computer alarm and meters mounted l on the Main Control Board. There are also additional meters mounted locally in ,

the DC switchgear.

Instrument cables are not pericdically tested however the instrument ,

associated is calibrated in the loop (cable included) on a periodic basis. Any i

critical. instrumentation is duplicated and any significant deviation between two indications would cause a work request to be initiated.

3.7 Improved Surveillance Pronram Based on the results of the inspection program developed and implemented to address the ELP employee concern, NHY intends to improve the surveillance of the safety related electrical manway enclosures. The cable surveillance test program described in NHY letter SBN-1107 together with the ground fault detection system and instrument channel calibration program provides assurance that the safety related electrical cables sre capable of performing their design function.

To ensure that cable submergence does not become a concern at Seabrook i

Station, NHY "ill implement a water level nonitoring program for the safety l related electrical manuay enclosures that have cables routed within. A maximum I

water height in each enclosure will be estublished. Upon determining that the level is at or above the maximum water le rel the electrical manway enclosure will be pumped down to remove the water. The initial inspection frequency will be on a semi-annual basis. As experience is gained from the inspection program the inspection frequency may be adjusted.

The NHY inspections revealed minor corrosion at the base of the support. To ensure that the long term structural integrity is maintained. NHY intends to i

15

inspsct tha cable support in tha safety related electrical manw2y enclosures, that have cables routed within, every five years.

Based on the results of the inspection program and the suspected inleakage through the enclosure removable slabs and cover plugs, NHY will re-seal each safety related manway containing safety related cab:is prior to startup from the first refueling outage.

3.8 Safety Evaluation Water intrusion into safety-related electrical manways has been evaluated and determined to have no adverse impact on plant safety for the following reaeons:

Cable Qualification o The underground electrical cables were originally specified, qualified, and procured for use at Seabrook Station for not only wet and dry applications, but also for LOCA conditions. The environmental conditions during a LOCA are more severe and, therefore, bound the mild environments to which these underground cables are subjected.

o The cables were procured to stringent nuclear and commercial industry l

specifications, which required tests to verify insensitivity to moisture by Accelerated Moisture Absorption fests. Using Arrhenius methodology, the insensitivity to moisture has been demonstrated to be greater than 40 years. I o A review of industry experience has concluded that these types of cables are insensitive to the submergence in underground applications.

1 o The chemistry reviews have yielded no chemicals that would be incompatible with cable materials.

Structural Qualification o The design of the cable support structures has significant margins on allowable stresses and margin to failure.

o Possible degradation over the life of the plant due to water intrusion 16

.~ _ __. _ _ _

would not signir'icantly reduco the design margins. l l

The results of the inspection program confirm the structural integrity o ;

Surveillance Programs o Megger tests on power cables have been conducted frequeatly. Meggering would indicate the breakdown of insulation due to moisture intrusion. '

o Megger' tests done to date have generally had results several hundred times higher than the minimum required.

4.0 CONCLUSION

S

{

The employee concern expressed to ELP was a valid concern based on the ,

information available to the employee. The NHY inspection program developed in response to this concern identified the presence of water in the safety related electrical manway enclosures and that safety related cables were submerged. NHY documentation and consultant reviews confirm that the electrical cable is^ l qualified for submergence. The NHY review has determined that the water surrounding the safety related electrical cables has had no detrimental effect on the cables or the support structures. NHY will initiate surveillance programs to monitor water intrusion into the safety related electrical manway enclosures,9ML-6 h4. m44a .;t++Ad"t & y and remove the water in accordance with the surveillance program. The cable support structures will be inspected on a periodic basis to maintain their condition on s long term basis. The manway enclosures will be re-sealed to minimize the water inleakage flow paths.

The NHY inspection program has confirmed the following information relative to the ELP employee concern.

1) The safety related submerged electrical cables pose no threat to the safe operation of Seabrook Station.

2) All safety related electrical manway enclosures were identified and inspected. The inspection program also included an inspection of the met tower electrical manway enclosure. This represents twenty-nine (29) 17

electrical manw2y snclosures. A total of ons hundred elevzn (111) electrical manway enclosures that provide service to Unit I were identified.

3) chemistry samples confirm that the water in the electrical manway enclosures is fresh water from ground water inleakage. The water is not seawater. This is further confirmed by enclosure elevation drawings and differences in as-found water levels in adjacent manway enclosures.

4) The cable supports were reviewed as part of this evaluetion. Substantial-design margin exists in the support design calculations. The inspection shows minor surface rust and some instances of minor localized pitting.

These conditions have been evaluated and found to be acceptable.

5) The electrical manway enclosures were not intended to have a drain system and provisions for permanent sump pumps, provisions for electrical power and alarm systems for the pumps. The enclosures were designed to minimize water l inleakage. The re-sealing and level monitoring program established as a result ci NHY's inspection will minimize water accumulation in the l electrical manway enclosures. The small sumps fabricated into the vault ,

enclosure are intended to provide a inw point for de-watering, as necessary. l

6) The only evidence of slime appears to be lubricants applied to the cable to l facilitats pulling the cable thr: gh the underground conduit ducts. The lubricant is compatible with the cable materials. In one electrical manway enclosure (WO6), between the Turbine Building and the outside of Containment, a white deposit was found. This white deposit waw luentified as calcium carbonate. This material does not have a detrimental effect on I the electrical cable or the conduit ducts.

7) Extensive evaluation of the cable that is submerged in the electrical manway enclosures confirms that the ble is qualified for operation in the submerged condition. Tha water environment identified via chemistry samples identified no substances tnat would be detrimental to the cable material.

8) The cable condition was inspected including the cable bend radius. All i i

18 l l

1

attributos ware satisfactory, there vara no b:nd radius violctions. The

~

cable covering showed no signs of deterioration.

Deer Chelrmen Carr:

Employees Legal Project (ELP) wes contected two degs ego by e former electricien et the Seebrook Nucleer Plent who hes e concern ebout e situction et Seabrook thet he believes poses e threat to the safe operation of that facility. ELP interviewed the Individuel, who wishes to remein anonymous. At his specific request ELP is forwerding his concern to the NRC end requesting e prompt investigation of his ellegetion. A letter similer to this has been sent to the Regton I office.

The individuel stetes that three years ego he was part of e crew essigned I to enter the ninety-seven (97) cable manholes et the Seebrook Site to l secure electricel cebles to their permanent recks Upon removel of the menhole covers, the crew found the manholes flooded. The liquid in the menholes wes seltweter with other unknown substances. It covered the cebles in the menholes end wes becked up into the conduit that ran through the underground duct banks.

The individual had been involved with the instelletion of the conduit before the duct benks were formed up end. covered with solid concrete.

That work enteiled e requirement to put protective covering on the pipe unions prior to the piecement of concrete. This was to insure that the conduit would remain dry end prevent liquids from deterioreting the I covering of the cebles that the conduit would hold.

The individual and the inspectors on this job operelion were surprised when the crene removed the first menhole end the crew discovered the 1

The power cables themselves were covered with a thick slime. There wes

also e heevy, solid, whit'e deposit on many of them. In the menhole located between the corner of the turbine building and the outside of containment, ,

this herd, white deposit was so large thet the point of entry of the cable into the menhole from the four-inch (4") duct could not be seen.

2 The individuel believes that some of the power cebles that run through the i i menholes and duct banks are pert of plent's sr'ety systems. He believes i

thet those cables are sitting in e liquid that contains substances that could compromise the insuletion surrounding the line end result in e l

] systems feiture. He believes thet some of those cebles do not meet the 1 squipment qualifications for the e:tuel environment in which they ere !

instelled. He believes that the failure to c'onform to the bending radius in l some installetions combined with the constant submergence in unknown l liquids could result in a cable f ailure end electrical short. He believes that, should a f ailure occurin one cable, the close proximity of other cables submerged in e liquid could result in multiple cable failures. In any of the preceding events he believes the ability of the plant to operate sefely would be compromised.

SUMMARY

This document demonstrates that cables with cross-linked polyethylene insulation with chlorosulfonated ; polyethylene .or cross-linked polyolefin jackets and . ethylene propylene rubber insulation with chlorosulfonated polyethylene- or chlorinated polyethylene applications jackets are qualified for the potentially . submerged' in aanways .and vaults located. . outdoors -at New Hampshire' Yankee's Seabrook Station. This' demonstration is based on the facts that (1) .These cables . were procured as. safety related cables, even-though used.in safety'and non-safety applications.

I

,(2).

The application .in manways and . vaults is ;a mild environment and does not require specific qualification- .

-(3) The cables are premium grade cables qualified . to- Seabrook's worst case Harsh Environment.

(4) The cables have proven, by test, their ability to oprate.

properly considering the effects of 40 years of aging, postulated radiation exposure and worst case Loss-of-Coolant Accident.

(5) After the LOCA exposure testing, each cable has further demonstrated proper operation in a submerged' condition.

(6) The cables were procured to stringent nuclear.

! industry specifications, which additionally required tests to verify insensitivity to moisture by Accelerated Moisture Absorption Tests.

(7) The insensitivity to moisture been ham demonstrated- for greater than 40 years, using arrhenius methodology,.which has been accepted by the NRC when used to demonstrate long term exposure to Post Accident conditions, including submergence.

(8) A review of industrial e>Q trience has concluded also that i

these types of cables up insensitive to the postulated submergence and are therefore qualified for use in these mild environments.

(9)'

Chemical' compatibility to the fluids found in the. vaults has been evaluated. No incompatible-fluids were found.

The application of cables in manways and vaults outdoors at Seabrook Station- is a mild environment. The areas in which these cables are installed does not change'due to.any postulated accident-WYLE LABORaTOR8ES Huntsv04e Facdity a

R:p3rt N3. 17122-00 Pcg3 Na. 4 months at 90 0C. The cables were shown to be insensitive to moisture during these tests and this insensitivity to moisture is shown to be the equivalent of greater than 40 years at Seabrook. The equivalent moisture insensitivity time was calculated using Arrhenius theoty, which has formed the basis or accelerated aging methodology used and approved for Harsh Environmental Qualification including submergence qualification inside containment. NRC requirements for aging evaluations for harsh environment qualification are codified in 10 CFR 50.49, Reg Guide 1.89 and NUREG 0588.

Other nuclear plants have evaluated the effects of cable submergence on safety related cables. The "Waterford 3 cable Submergence Evaluation" was reviewed. This document shows that some of the same cable at Seabrook was evaluated for submerged use at Waterford, specifically Anaconda and Okonite cable. The results of LOCA testing, Accelerated Water Absorption tests, Arrhenius based Equivalent Age calculations, industry experience with submerged cable and an evaluation by Okonite conclude that these cables are also qualified for reater than 40 years in submerged conditions. The methodology ur ' by Waterford and reviewed by the NRC in their evaluation is essenc. illy the same as has been used by Wyle to evaluate the cables at Seabrook as it relates to outdoor submergence.

The conclusion is that these cablos are qualified for the mild environment application for installation in outside, underground level Manways and vaults at Seabrook Station which may be submerged for up to 40 years.

WYLE LABORATORIES Hufttsville Facahty

R0 port N3. 17122-00 Pago No. 3 i at Seabrook. Since tho' environment does not change, no specific qualifications are required, never the less, this document-provides the basis for demonstrating that these cables are qualified for

. this application.

The cables located in the manways and; vaults are ' subjected0 to temperature conditions conservatively estimated to be 20 C (68 F).

Periodic submergence of portions of these. cables :is also postulated.

The results of testing for Harsh Environmental- Qualification ' and '

Accelerated Moisture Absorption Tests apply; to the; subject' cables '

because . these cables were procured as safety related cables, even though used in safety.and non-safety applications. _

For mild environment c a b l e s ,' n o specific regulations ' exist which

require demonstration of . environmental. qualification, _ only conformance to specification and 'a maintenance program are required. Never the less, this document provides the evidence, hY -

tut, that the cables are qualified for this environment. The '

conditions ~ of the. environment are- enveloped, by the: harsh

, environmental qualification, which has demonstrated that the cables i are qualified to the worst case environments and accidents at Seabrook Station.

The harsh envitonment qualification of these cables has been

, performed by IEEE Standard tests. These IEEE tests have been performed on each style of cable at Seabrook. The peak temperatures are -in excess of 340 F 0 ,

, pressures in- excess of 60 psig, radiation levels in excess of 2E8 RADS, 40 years of aging, chemical sprays and post accident submergence. The voluminous .

results of these tests and associated files have been rf orously and thoroughly reviewed by Seabrook and . consultant personnel and have NRC.

previously been audited and found . to be in compliance by the The cables at Seabrook have been procured for'all applications and 4

provide optimum performance in electrical stability, tensile strength, flexibility, non-aging, abrasion resistance, dynamic cut through resistance, minimal heat distortion, radiation stability, self-extinguishing non-propagating fire characteristics and Accelerated term exposure to moisture.

Water Absorption tests to verify-insensitivity to'long :

The service requirements - are '(a) indoor,- galvanized steel, solid bottom tray, (b) underground non- '

metallic ducts, (c) underground metallic ducts, galvanized steel conduit and (e) wet and dry locations.(d) exposed, i The Accelerated Water Absorption tests verify acceptable' electrical' properties after long duration tests while immersed at elevated tempeutures with constant voltage potential applied. The test durations were a minimum of 14 days at 75 C to a maximum of' 36 0 WYLE LABORATORIES Muntsyme Facsiity

The cables were electrically energized during the LOCA simulation (Attachment 4.1.2) except for the times when l insulation resistance (IR) measurements were being taken (see Attachment 4.1.3 for IR values). j Following the 30 day LOCA simulation, the cables were removed l from the double mandrel, straightened and then rewound around a mandrel with a diameter 40 times that of the cable diameter.

The coiled specimens were then immersed in a tank of tap water at room temperature and were subjected to a hi-pot withstand test for five minutes using a potential of 80 VAC RMS, 60 Hz per mil of insulation. The results of this test are shown in Attachment 4.1.4. All cables withstood the hi-pot test.

All cables demonstrated satisfactory performance during exposures simulating normal service, a LOCA and subsequent cooldown, and had substantial margin of life remaining by withstanding post-LOCA bends at diameters 40 times the cable diameters and high potential tests while submerced at 80 VAC per mil of insulation.

LOCA tests for the subject cables ranged in _ length from 30 '

days to 130 days. The peak temperatures and pressures ranged- )

from 341 to 3900 F and 66 to 112 psig respectively. During uhe LOCA testing each cable was exposed to a highly conductive and i acidic chemica) spray. The cables were also' continuousAy energized during the LOCA test to voltages which exceed the nominal operating voltages.

After the cables survived even the deleterious effects of I LOCA, radiation aging and chemical spraying, each cable . was ]

also subjected to and passed a cost accident submercence test.

These tests demonstrated operability of the cable- in a l

submerged condition after exposure to a LOCA test. l l

o Construction B: 2kV, #6, 7X TC , .055" Okonite insulation, .030" Okolon jacket. (EPR)

Two 22 ft. samples, 1 unaged, 1 aged.

The test profiles are shown in Attachments 4.3.2 and 4.3.3 for Construction A and B respectively.

The results of the test are as follows:

Construction A The 130 day Post-LOCA Submerced Withstand Test demonstrated that the samples were in excellent condition. Charging currents of less than 2.5 mA were measured. The SIC of the aged and unaged samples were 3.52 and 3.20 respectively, at 80 V/ mil. The % PF at 80V/ mil were 2.37 and 1.7 while the insulation resistance values were 6,390 and 41,800 M ohms-1000 ft., respectively. AC dielectric breakdown was greater than 16 times rated voltage (unaged failed 15.4kV), aged failed 10.6 kV). Per cent retention of tensile strength for the aged and unaged samples were 75% and 101% respectively. Per cent retention of elongation was 27% and 15% respectively.

Construction B The 130 day Post-LOCA Submerced Withstand Test demonstrated that the samples were in good condition. Charging currents of 5.5 mA were measured on each sample. The SIC, % PF, and IR values for the unaged sample were 3.98, 7.33% and 3,300 M ohms-1000 ft. respectively. The aged sample's SIC, % PF and IR were 4.74, 10.53% and 3,080 M chms-1000 ft.

The cables were electrically energized during the LOCA simulation (Attachment' 4.1.2) except for the times when insulation resistance (IR) measurements were being taken (see Attachment 4.1.3 for IR values.)

Following the-30 day LOCA simulation, the cables were removed from the double mandrel, straightened and then rewound around a mandrel with a diameter 40 times that of the cable diameter.

The coiled specimens were then immersed in a tank of tap water at room temperature and were subjected to a hi-pot withstand test for five minutes using a potential of 80 VAC RMS, 60 Hz per mil of insulation. The results of this test are shown in Attachment 4.1.4. All cables withstood the hi-pot test.

All cables demonstrated satisfactory performance during exposures simulating normal service, a LOCA and subsequent cooldown, and had substantial margin of life remaining by withstanding post-LOCA bends at diameters 40 times the cable diameters and high potential tests while submerced at 80 VAC per mil of insulation.

8,1 Review of '"Waterford 3 -Cable Submergence Evaluation" (Reference 17)

The purpose of this evaluation was'to' demonstrate that cables which were subject to submergenceLat Waterford 3, were.eapable of. performing their intended safety -function after . full l exposure to'LOCA conditions followed by subsequent submergence conditions for a minimum of 120 days plus 10% margin.

In order to adequately . demonstrate this two questions were answered:

(1) After 40 years. of service does exposure to ,LOCA degrade the insulating. characteristics of a cable _ to such a degree that any further! degradation.after submergence may be reason to doubt the continued operability of that-cable?

(2) Does the cable l- insulation in 'a -submerged condition continue to degrade to such'a degree that the operability "

after 132 days is in serious q1stion?

Waterford identified that the - determining cable' performance characteristics were: parameters '

IR = Insulation Resistance. A . measure l of an- insulating material's capacity to maintain its resistance to current flow-to the outside medium such as water, cable trays and' conduit-and is measured in Ohms. Damaged insulation or insulation which has had significant moisture. intrusion or diffusion will i result in low or zero valves in Ohms. Temperature will also

cause a variation in IR vala ~ ,

l SIC = Specific Inductive Capacity. This value is a measure of an insulating material's ability to store a charge and has a significant bearing on insulation . moisture resistance. . Cable insulation - can be ' considered as a capacitor . since it is a ;

dielectric between 'two or more conducting i surfaces .and, the '

introduction of water into this dielectric will-significantly-effect the capacitance resulting in' change in SIC.-The SIC of a vacuum is 1, thus, v.he greater the ' . SIC , the better the dialvtric proprties. of the : insulating material. Lower values of SIC' indicate moisture within the~ dielectric. '

1 PF = Power Factor.~This;is a measure'of the. power losses that L

occur in a cable as the result of the storage of energy in the cable insulation and is sensitive to the moisture content of the insulation. The higher the PF the greater; the moisture WYLE LABORATORIES Muntsyme Facahty'

It is also concluded that Anaconda cable is capable of withstanding a LocA followed by subsequent submergence for a peried in excess of the Waterford 3 120 day post accident requirement plus a 10% margin.

8.1.2 Okonite The Okonite Rc 't No. NQRN-1A, Rev. 5 dated October 24, 1988, perfor; navironmental qualification testing on two groups of waite cable. Each group had two samples tested, one which was fully aged prior to LOCA and one which was unaged for a total of four cables in the test program. Cable group A was a 600 volt #12 AWG insulated with 0.030 inch Okonite EPR insulation with a 900 C rating and 130 C cverload rating. Cable group B was a 2kV #6 AWG insulated with 0.055 inch Okonite EPR insulation and a 0.030 inch Okolon chlorosulfonated polyethylene jacket.

The two Cable A samples were 25 feet in length and the two Cable B samples were 22 feet in length.

The aged sample from0 each group was firs thermally aged for 21 days at 150 to simulate 60 yeare. at 135 0 F followed by exposure to 200 MRADS of irradiation. All four cable samples were subjected to a 130 day LOCA test while mounted on a mandrel in which a peak temperature and pressure of 345 F/110 psig minimum were obtained in two initial transients. During the LOCA test, the tested cables Vere energized with 600 VAC and 18 AMPS. A chemical spray was used during the first 30 days of the test followed by steam and water spray throughout the remaining 100 days.

The chemical spray consisted of:

o 3000 PPM boric acid (0.28 molar) o 0. ')6 4 sodium thiosulfate and pH = 10.5 controlled with sodium hydroxide IR measurements were taken periodically during the LOCA test by applying 500 VDC for one minute. See Attachment 8.1 2.1 for a plot of the IR test results.

After 30 and 130 days into the test program, the cable samples were removed from the LOCA chamber uncoiled from the mandrel, straightened and recoiled around a 40X mandrel and immersed in tap water. The samples were then subjected to an 80V/ mil high potential withstand test for WYLE LABORATORIES Huntsville Facihty

The results of the IR measurements taken during the LOCA test ?^dicate that the IR values vary inversely with the tempere.are of the chamber- (increase with decreasing-temperature) as opposed to being strongly influenced' by the presence of the chemical spray, since post aging.and post-LOCA test IR values were essentially unchanged. See Attachment 8.1.1.1 for plots of the test results.

The conclusion that the chemical spray under pressure has a.o significant impact is based frout the fact that as pressura and temperature were lowered simultaneously, the measured IR values increased and responded rapidly due to the immediate loss of imparted energy to the cable insulation. If there had been significant deep meisture penetration, IR values would have recovered in a lagging fashion to much lower values, if any significant recovery was to occur.

A separate unaged sample (unrelated to the LOCA test, waich can be found in Anaconda document- #8211211) of a 1/C #12 AWG Anaconda conductor with 30 mils of FREP in sulation was 0

subjected to a 26 week water immersion test at 90 F with 000 VAC continuously applied. The reported values for SIC, PF and IR at the start and co.iclusion of the test are as follows:

See .1.1.2 for the water immersion IR test results.

The absence of chemicals in the immersion water is not considered significant since the LOCA test has demonstrated insulation.

that these chemicals do not attack the cable Since the Anaconda cable paissed the LOCA with sufficient margin and no ynificant loss of insrlating properties, the 26 week i aersion test at 90 C0demonstrated submerged cablet will not be subjected to ::ontinual degradation.

. medium such..:s steam, water or - chemical composition.-

pressure' variations at a constant temperature will' change cable IR' values because the imparted energy (BTU's per unit volume) to the cabla insulation is varied. l 1

2. Cable insulation resistance values were demonstrated not- j to be degraded to a significant level upon conclusion of '

the LOCA ' exposure to where post accident operability of the cable was a concern prior ~ to - the potential of submergence. In ' some situations the,IR values remained essentially unchanged, others improved, and- others decreased to lower but more than adequate values.

Therefore, for che purposes of post-LOCA submergence testing and l demonstratin'g operability, aging is not a significant i factor. This can be attributed to the the cable manufacturing process, fact that during i the curing of the I f.nsulation is typically performed by heat or radiation.

The IR values obtained from the tected cable indicates that the temperature of the cable insulation is more of a {

significant factor in the variation of the insulation resistance than to the other environmental parameters around the cable insulation. This is attributed to the IR plot of the agen and unaged Group A cable, which did not contain a jacket. The IR values did not change significantly at the start and end of the LOCA test; however, significant variations did occur with major temperature variations. This data strongly suggests that IR values are more temperature dependent, increasing rapidly with decreasing temperature and pressure rather ,

than chemical spray dependent. This position and

{

conclusion cable. is the same as addressed for the Anaconda As a consequence such conditions as subr mence will not alter the cable IR characteristics.

9.1.1.1 Ethylene Propylene Rubber According to the Handbook of Plastics and Elastomers (Reference 14), pages 4-54, 4-55, and 4-60 (Attachment 9.1.1), EPR has good to excellent resistance to water, neutral salts (including sodium chloride), acids and caustics. It is essentially unaffected by alcohols and is quite resistant to phosphate-based hydraulic fluids.

However it has only fair to poor resistance to aliphatic, aromatic and halogenteed hydrocarbons and diester-type synthetic lubricants. It also has poor resistance to esters, ethers and ketones. The ratings for organic compounds are based on 100% concentrations.

New Hampshire Yankee's testing of 27 water samples taken from the vaults (Attachment 9.1.2, Reference 15), shows a pH range of 7.0 to 10.5, salinity less than 3.64% as

Resource Analysts, Inc. tested four representative samples of water from the vaults for the presence of volatile organic compounds (Attachment 9.1.4, Reference 18). These compounds might have been driven off in New Hampshire Yankee's total organic carbon tests. Three of the samples tested have no detectable organics.

It is not unusual for a power cable to be required to operate in an environment alter-nately wet and dry. To detemine the long tarin water stability of a cable, a sample insulated with a thin wall dielectric is immersed in water at an elevated temperature to accelerate the deteriorating effects of moisture. Monitoring the electrical properties provides an indication of long term behavior. Based upon actual experience

                , with installed cables over many years insulations which have the caoability of withstanding total uter funersion at 90C should be capable of a life in excess of a generating statiort's designed life in an environment of 1005 hus'dity.

Figure I shows long tem 90C uter immersion on a 1/C #14 AWG Okoguard insulated cable, and Figure I-A shows comparable data on a 1/C #4/0 AWG Okoguard insulated power cable.

1. Anaconda has provided additional documentation, the Attachment to i Report F-C4969-1 (Reference 3) and Acton Test Report No. 16587-81N, } l Rev.1 (Reference 8), which justifies the initial temperature rise to 375'F within 15 seconds and covers the 340*F second plateau for i specific Seabrook requirement.

2. Anaconda has provided analysis (Reference 5) which extrapolates the post LotA test ofJ5 days at 214*F to 680 days at 71*C using the 10*C rule. However, as allowed by NUREG-0588, using Arrhenius methodology and the above test data, the cables will have a thennal l life of over 1 year at 71.5'c for an activation energy of 1.22. .

The activation energy of the EP insulation is determined from the Arrhenius Plot given in Reference 7 by using two point on the plot and the Arr$enius Equation: X1 /X2 . , A/K(1/T1 - 1/T2 ) Where Xj = Service Time (Hours) X2 = Test Time (Hours) l* A = Activation Energy (eV) . K = Boltmann's Constant = 8.617E-5 I < Ti = Service Temperature (*K) T2 = Test Temperature (*K) Therefore A= Activation Energy = 1.22 eV .

                                                                                                                      ,            l These control cables are nc. expected to develope a wire                                     I touperature greater than 71.S*C (Reference 4). Therefore, the 115                           j             <

days LOCA and post LOCA test descastrates that this equipeent is i ! qualified for the required post accident operating time with a j ! large margin. !

3. An%onda has provided justification in Reference 5, point 5 for the l l Gifference in chemical spray pH between the Seabrook required and i '

the one used it the testing. Anaconda, in its justification, shows that the variation in flow rata of the spray and pH used in the !' testing does not affect the cable qualification. In view of the , above we consider that the test pH of 9.5 is adequate to justify j qualification requirement for Seabrook. ; t Rayision 1 5247m Page 10 of 13

1226~. ~I j l 1 ANALYSIS FOR SUBMERGENCE QUALIFICATION OF OKONITE POWER CABLE The cables under evaluation for submergence qualification have been supplied by the Okonite Company in accordance with the UE&C Specification No. 9763.006-ll3-03 for the Seabrook Station. Based on the available qualification test documentation supplied by the Okonite Company (Okonite

Test Report #PSCNH 0978-1, Rev. 2,12/20/82), an analysis is performed to qualify these cables under submergence conditions which is discussed celow:

These cables will be subjected to submergence in only two areas of the plant: Containment Building and Main Steam Feedwater Pipe Chases (Reference 3). During qualification testing (Reference 4), similar cable specimens (aged and unaged samples) were sutjected to pressurized steam, chemical / water spray during LOCA and post-LOCA testing. Prior to LOCA and post-LOCA testing, the aged specimens were thermsily aged and irradiated equivalent to the end-of-life conditions at the plant. In the LOCA test chamber, the cable specimens were installed on a mandrel and saturated steam injected into the chamber which developed an internal temperature of up to 345'F and peak pressure of 112 psig. A colution of boric acid sprayed over the mandrel continuously. The concentration of the chemical solution was more severe than the solution specified for the Seabrook Plan (Reference 7, QEWS). The cables were energized with their rated voltage and current. The insulation resistance of Oc cables measured time to time during the test. The LOCA tes. contir,ued for 30 1 days. The perfomance of the specimens was satisfacto'y throughout the LOCA l test and the lowest insulation resistances recorded during the peak I chamber temperature conditions were 1.7 Meg Ohms-1000 f t. f or the aged l sample and 1.3 Meg Ohms-1000 ft for the unaged samples (Reference 5). Both the samples maintained electrical load tr.roughout the LOCA testing. At the concit, ion of the 30-day LOCA test, the cable samples were subjected to 40X00 bend and 80V/ mil AC, 5 minutes insnersed in water withstand test and passed. , Reference 4. Appendix 4. demonstrates that the actual test temperature profile is much more severe than the postulated Seabrook accident profile for 1 year if the time to equivalent damage approach is considered, l 4943m Page 1 of 3

Athough the cable specimens were not submerged during the testing, tne specimens were sprayed continuously with chemical spray solution under high temperature and pressure rising up to 112 psig as against Seabrook peak pressure of 60 psig. For the entire 30-day duration, the test pressure profile was also much more severe than the plant pressure profile (References 2 and 4, App. 5). The test chamber maintained a 100% relative humidity condition throughout the test due to the presence of ' saturated steam and chemical spray. At the conclusion of the LOCA testing, the specinens were further tested in a steam chamber with water spraying continuously (Reference 4). The temperature of the test chamber was maintained at 212*F and pressure varied from 0-2 psig (Refer 2nce 4, App. 5). The specimens were also energized with their rated voltage and current and IR measured. Both samples maintained electrical loading throughout the testing and the IR recorded on the 129th day of the test at 212*F was 270 Meg Ohms-1000 ft. for unaged cabic and 100 Meg Ohms-1000 ft, for aged cable. The total duration of this post-LOCA test was 100 days. At the conclusion of the test, the specimens were also subjected to 40XOD Bend and 80 V/ mil AC, 5 l minutes immersed in wate" withstand test and passed. J l In addition, unaged cable specimens (similar to Seabrook supplied cable) ! were subjected to Long Term 90*C Water Immersion Accelerated Test I (Reference 4, App. 8). Results of which demonstrates no malfunction up to 36 months. 1 Plant cables (P.O.113-03) will be sabmerged to a maximum depth of 3' l under water (chemical solution in the case of the containment cable) in ' only two areas of the plant: Containment Building and Main Steam Feedwater Pipe Chase area (Reference 3 and 6). The containment zone is the worst postulated environment area for temperature, pressure, humidity, radiation, a:; well as submergence which contains a chemical solution. While submeged under water with a 3' water head, the plant cables will be subjected to a static pressure of only 1.3 psig (assuming sp. gravity of water only). This additional pressure due to submergence is l considered negligible to cause d radation compared to the test pressure applied to the cable during the L A te:t. Other than the postulated peak temperature condition during design oasis events, the cable temperature can be assumed as a maxima design temperature of 90*C (194*F). As discussed above, the LOCA exposure with high temperature, pressure,1005 relative humidity due to saturated steam and continuous , spray of chemical solution is adequate to account for the submerged 1 condition of the cable for the entire 30-day duration. In addition, the i 100-day post-LOCA test can also be considered equivalent to support submerged condition as the steam temperature was above 90*C and water sprayed continuously. The accelerated water imersion test also assures ! moisture resistance of the insulation of the cable. 1 I 4943m Page 2 of 3 { I I

Although ths : Wee specimens were not submerged during the steam / chemical I spray testing, the specimens were sprayed continuously with chemical j solution under high temperature and pressure rising up to 66 psig. In ! general, the test temperature / pressure profile was more severe that the i specified Seabrook postulated profiles. The test chamber maintained 100% relative humidity condition throughout the test due to saturated steam condition and chemical spray, t 1 The above cable specimens were further exposed to a 85 day Post LOCA testing in a steam environment with chemical spray similar to the ! original LOCA testing (Reference 5). The temperature and pressure during ' this test was 212*F and 0-3 psig respectively. Chemical solution was sprayed continuously over the cable specimens during the test while the speciment were electrically energized witn rated voltage and current. All specimens except Specimen #37.1 E maintained their electrical loading { throughout the test. The Specimen 37.1 E failed during the test due to some test set up which do not affect the qualification of the cables. Insulation Resistance measured during the test were satisfactory. At the cor:lusion of thi: 85 day additional post LOCA testing, the specimens were subjected to 40X00 bend, 5 minutes immersed in water withstand test and passed. 4 Test results of the Accelerated Water Absorptior Test performed in accordance with the ICEA PUB No. 5-68-516 on unaged cable samples have been reviewed and also found satisfactory (Reference 6). It may be noted that even at 90*C water temperature the cable perfornance was found satisfactory for up to 6 months without any noticable malfunction. Reference 3 identifies that the subject 600V Ar.aconda Control cables will be submerged subsequent to design basis event in various areas of the plant. The worst environmental area is the containment building, where the cables will be subject to high temperature, humidity, pressure, radiation, chemical spray as well as submergence. The raximum depth of submergence is 3' (Reference 7). Therefore the cables will be subject to a static pressure of 1.3 psig (assuming sp. gravity of water). This pressure is considered negligible with comparison to the cable specimens tested during the LOCA test as discussed above. 4 Page 2 of 4

pressure,100% relative humidity due to' saturated steam and continuously i spray of cheinical solution is considered adequate to account for the . submerged condition of the cable- for the entire 30 days duration. It has been verified by using Arrhenius methodology that the LOCA test i e temperature condition envelope the required Seaorook postulated conditions with margin (Reference 8 EQ Assessment Report Note 2). In actual plant installation the cables will not be degraded to. that axtent as it was during the testing. In addition the cables were further exposed to 85 day post LOCA testing in steam and chemical spray - environment, which is also considered equivalent to support the submerged condition 'of the cable.

In view of the above discussions, it can be concluded that the subject Anaconda Control cables supplit.d to Seabrook can withstand sabnerged conditions identified in Reference 3 due to postulated design basis events for 30 days. ,

ANALYSIS FOR SUBMERGENCE QUALIFICATION OF ANACONDA INSTRUMENT CABLE The cables under evaluation are 300V Inst.rumentation Cable supplied by I Anaconda Ericsson, In:. in accordance with.UEAC Specification No.- " 9763.006-113-18

for Seabrook Station. Based on the available
qualification test documentatiorfsupplied by Anaconda (References 4, 5 .

and 6), an analysis has been perfomed to qualify these cables under submergence condition which is discussed below: 0 These cables will be subjected to submergence in the Containment Building 1 and Main Steam Faed Water Pipe Chase areas of the plant (Reference 3) i subsequent to Design Basis. Events. During SLB/LOCA qualification testing (Reference 4) cable specimens (similar to Seabrook) were subjected to pressurized steam, temperatures up to 385'F and chemical spray. Prior to this testing, the cable . specimens were thermally aged and irradiated equivalent to the end of

     ~                                                                                                         '

During this i 4 testing, the cable specimens were energised with their rated voltage and current, and insulation resistance was measured at various intervals. ' The performance of the specimens was satisfactory throughout_the SLB/LOCA

test and the minimum insulation resistance recorded was satisfactory except for one specimen (37.1 E) which failed during the test due to test

          ?quipment set-up problems. Electrical loadings were also maintained throught.ut the test except for specimen 37.lE, which was removed from the test when the charging current exceeded 1 Amp to maintain its potential.

At the conclusion of the SLB/LOCA testing, the cables were removed from ! the mandrel, straightened and again coiled around a mandrel which had a diameter approximately 40 times of the cable diameter. ' The mandrel was icmiersed in tap water at room temperature for 1 hour and then subjected to thickness.a 5 minute high potential test based on 80V/mi) of insulation The results of this test were satisfactory. , l l o i

solution under high temperature,and pressure rising up to 66 psig. In general, the test temperature / pressure profile was more severe that the specified Seabrook postulated profiles. The test chamber maintained 1005 relative humidity conditions throughout the test due to saturated steam condition and chemical spray. The above cable specimens were further exposed to a 85 day Post LOCA test ' with a steam environraent and chemical spray similar to the original LOCA - testing (Reference 5). The temperature and pressure during this test was 212'F and 0-3 psig respectively. Chemical solution was sprayed continuously over the cable specimens during the test while the specimens were electrically energized with rated voltage and current. All specimens except Specimen #37.1 E maintained their electrical loading i throughout the test.' That Specimen 37.1 E failed during the test due to ti.e test set-up does not affect the qualification of the cables, j Insulation Resistance measured during the test were satisfactory. At the conclusion of this 85 day additional post LOCA testing, the specimens were subjected to 40X00 bend, 5 minutes imersed in water withstand test and passed. i Test results of the Accelerated Water Absorption Test performed in ) accordance with the ICEA PUB No. S 68-516 on unaged cable samples have !' been reviewed and also found satisfacton (Reference 6).It may be noted that even at a 90*C water temperature, the cable performance was found satisfactory for up to 6 months without any noticable malfunction. Reference 3 identifies that the subject 300V Anaconda Instrument Cables will the be submerged subsequent to design basis events in.Various areas of plant. where the cables will be subjected to high temperature, humidity,T pressure, radiation depth of submergence, chemical spray, as well as submergence. The maximum , is 2'0" (Reference 7). Therefore the cables will be subjected to only a static pressure of 0.87 psi (assuming sp. gravity of water) . This pressure is considered negligible in comparison to the 66 psig pressure the specimens were exposed to during the LOCA. test

discussed above. k i ) 03181

                                         -continue d-As shown above, t.he 30 day L'CA test exposure with high temperatures and pressures.1005 relative humidity due to saturatcc steam and cor.tinuous spray of chemical solution is considered adequate to account for the submerged condition of the cable for the entire 30 days duration. It has been verified by using Arrhenfurfmethodology that the LOCA test              ,

temperature condition envelopes the required Seabrook postulated -

conditions with margin-(Reference 8. EQ Assessment Report Note 3). In actual plant installation, the cable, will not be degraded to the extent they were during the testing. In addition, the cables we e further exposed to an 85 day post LOCA teri in a steam and chemical spray environment, which is also considered equivalent to support the submerged condition of the cable. In view of the above discussions, it can be concluded that the subject Anaconda Control cables supplied to Seabrook can withstand the submerged conditions identified in Reference 3 due to postulated design basis events for 30 days. r 03181 Page 3 of 5

WATERFORD SES UNIT 3 WATER SEEPAGE FROM CONDUTTS AT ELEVATION -35

Reference:

Ebasco memorandum ES-10331-84 dated October 26, 1984 We have reviewed the questions raised by NUS relative to concern #19. This involved damage to cables immersed in water. In the 40 plus years of experience of the electrical engineers in our group, along with consultation from other company L gineers, none have sean any damage to cable caused by'staply being immersed in vacer. This expertence is obtained from all types of expc.iure ranging from power plants to substations, and involves cables that may have been immersed in water for an excess of 20 years. This er?artence is backed up by the referenced memorandum. We do not feel.that it is necessary to even perform a cost benefit analysis, let alone a qualification program, or to reroute cable. If you have any questions, please let us know.

Report No. 17122-00 Attach:nent 8.2.1.1 Paga No. 8.2.1.1-3 00T2Sj984 MEMORANDUM ES-10331-84 ' October 26, 2.984 b O To: D. Dobson gb ; From: M. K. Yates . Subj ect: LOUISIANA FWER & LIGHT COMPANY WATERFORD SES UNIT NO. 3 VATER SEEPACE FROM CONDUITS AT ELEVATION -35 rr In respone to questions raised by NUS relative to concern no.19 Electrical Engineering has reviewed the available information on the water seepage problem affecting conduits and low-voltage cables at the Waterford Planc.and offer the following cessnents: 1.. Water ingress into the conduits is most probably taking place at conduit joints. Because there may not be a tight bond between the conduit surfaces and the concrete surrounding it,' underground water which filtered into the basemat through the hairline cracks, has a natural path along the external surface of the conduits. . -

       .        2.      Due to water ingress, the cables in these conduits will be immersed in water.          The insulation of the cables involved has been qualified by extensive type testing under. vater immersion for up to 2 years, with water at 90 degree C and 600 Y applied potential. These tests have shown the excellent water stability of these insulations (with no failures occurring during the up to two-year testing). It is to be noted that the'affected' cacies viIl be exposed to substantially less severe conditiens than those of these tests,              i,.e., water temperatures well below 90 degree C and operating voltages of 480'Y or less.

3. Because of the excellent results of the water isusersion tests, it is :

conservatively estimated that the service life of these cables under the. installed conditions will exceed 10 years as comptred with their 40 year service life espectancy under normal installed conditions. ;

4. It should be noted that no qualificatica program presently exists in the industry to predict incipient cable failure of the remaining life of cables installed under water. However it should be pointed out that cables of' similar construction and materials have been installed immersed in water in the Gulf area for more than 15 years without s' failure.

Concern has been expressed by the Regulatory Staff as to the compatability of St. Lucie underground cable with the service environewat, i.e., have the cables been adequately qualified for the conditions they might experience during their service life. The propriety of utilising the cables for this service has been reevaluated and the suitability for the service er.vironment reaffirmed. Basically, the environmental qualification study consisted of , three parts, namely. I

1. Insitu Cable Emperience . I The underground cable system of Miami Beach closely duplicates the St. Lucie service environment. The performance of cable un this I systars was reviewed to determine whether or not the dry alternately wet and dry, and flooded conditions experienced by the Miami Beach !

cable results in cable failure due to deterioration. This review, which included all failure data since 1945, indicates that there has "never been an electrical deterioration failure of any kind in the Miami' Basch systes. l

2. trperimental confirmation 1

Four cable manufacturers have performed independent tests to demon-strate that the modern insulations utilised for St. Lucie cable have superior resistance to electrical datarieration than the insu-lations that have performed so well at Miami Beach. Each echte asaufacturer has independently demonstrated that the modern insula-tions are superior. Thse, the St. Incia cable life will undoubtedly exceed that of the Mird hach caMe.

3. Expert Opinion Two nattena11y recognised cable esperts have reviewed the cable for the intended service environment. Both conclude that it is adequately qualified for the servica environment.

How- l ever, technological advances has made available never superior insulating materials, namely, crosslinked polyetheline (xLPE or CLPE) and ethylene propylene rubber (IPA or EPN). These never insulations have been utilised I widely by the industry for the last five to ten years. They provide superior ' I performance to that experienced with butyl rubber. Since an acceptable ioservice data base is available for the butyi rubber insulation, qualification of the never asterials is readily accomplished ! through laboratory tes-ing. The new materials and the butyi rubber must i undergo appropriata idestical tests. To qualify the new atterials it is necessary and sufficient that these materials have resistance to electrical deterioration equal to or greater than butyl rubber. The test results clearly indicate the superior characteristics of these new materials.

Waterfoni 3 . l _ Louisiana Power 4 Light , i 4 Your letter of Novueber 10,1986 requests infomation on 01cnite/0knirm 300 volt power and control cables sith reference to possible water submersion. It is well 'snown and established that water has deteriorat' effocts on all in- I sulations. Thoso deteriorating effects are evidenced by things as loss i of dielectric strength, rise in poner factor and dialectric constant and lower-ing of insulation resistance. ;

The rato at which these deteriorating effe-te occur is the key question. The rate is dependant en temperative i.e., higher water temporatures increase the rete.

The rate is also dependenc c,a other things such as voltage stress, w21 thickness, and the presence of discharge. Righ stress increases the rato; thirmer walls at equal stress deteriorate faster than heavier walls; in the case of 600 volt cable the discharge cpsstion is neot. Over the years as insulation technology has fuyroved nero resistance to water has been built into insul iat ons. Attached is a chart abowing the behavior of 1 power factor vs. time of various insulations in 90*C water.
