The inspectors, in this instance, asked that documentation be provided in accordance with conditions 3 and 4 above to support the radiation qualification of the Dings brakes. At the time of the inspection, neither you nor the vendor e

provided the necessary documentation.

It is our understanding that the infor-

mation provided was newly assembled subsequent to the inspection.

In this case, t

a violation of 10 CFR 50.49 is sustained.

• t Per telephone conversation between P. R. Johnson of Yankee Atomic, T. P. White l

of Vermont Yankee and L. Cheung of NRC on June 9, 1988, we understand that the i

completion date for the resolution of the Rome Cabic deficiency (Item #5) will l

.

be revised from "prior to start-up from the next refueling outage" to

'

September 15, 1988 (reference: Yankee atomic memorandum W.O. #4440 dated June 9, 1988).

Your corrective actions will be examined during a future

Dear Sir:

Subjects'

Response to Inspection Reoort 87-19, Notice of Violation

-

This letter is written in response to your Notice of Violation, dated February 22, 1988 (Reference c)).

VIOLATION

-

As a resuit of the environmental qualification (EQ) inspection conducted on October 19-23, 1987 and in accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement i

Policy 1987), the following violation was identified:

10 CFR 50. A9 paragraphs (f) and (g), and paragraph (k) (for 00R Guidelins provision) require that each item of electrical equipment important to safety be qualified and that qualification must be completed no later than

Novetter 30, 1985.

Contrary to the above on October 23, 1987:

1.

Qualification of the EP/Hypalon cables was not established at the time of the inspection in that the qualification test report was invalid because of problems identified in ','nformation Notice 84-44 (inadequate

QA program, test equipment not properly calibrated, test deficiencies and test anomalies improperly documented, and test documents impro-perly controlled).

t 2.

The qualification of 3M ta.r splices was not established at the time r

of the inspection in that N type test report nor adequate similarity analysis was available in the EQ file to support the tape splices'

qualification.

,

3.

The qualification of Dings brakes in the Limitorque valve operator was not established at the time of the inspection in that the EQ file did not contain evidence to demonstrate the radiation qualification of the Dings brakes for application inside the drywell.

4.

The qualification of GE EB 5 terminal block was not established at the time of the inspection in that 1) the type test report did not demonstrate that this terminal block can perform its safety functions because low insulation resistance values were observed during the test and 2) no similarity analysis was available in the EQ file for GE EB-5 and GE CR 1518 terminal blocks.

5.

The qualification of Rome XLPE/PVC cables was not established at the time'of. the inspection in that the test conditions did not envelope the required service conditions (303*F for four hours vs 325'F for

-

three hours).

6. - The qualification of Lewis PE/PVC instrumentation cables was not established at the time of the inspection in that no valid test report was available in the EQ file to support the qualification of this type

,

of cables.

This is a Severity Level IV violation (Supplement I).

RESPONSE The Vermont Yankee Nuclear Power Corporation response to the violation will address each of the six items described above separately as follows:

1.

This ites deals with Cerro cable.

During the inspection, Vermont Yankee was able to obtain a Franklin ReseaEc6~ Center test repor't which verified

~

the qualification of the cables. A qualification documentation review (QOR) package revision is in progress to include this report and to upgrade the file as required. When the additional information is incorporated, this QOR will document, in accordance with the Division of Operating Reactor (DOR) Quidelines, that equipment subjected to harsh environmental conditions will perform its intended safoty function.

This action will

.

bring Vermont Yankee into full compliance with 10 CFR 50.49.

This will be completed by May 1, 1988.

2.

Item 2 involved 3M tape splices.

During the inspection, Vermont Yankee was able to obtain a letter from Wyle Laboratories, dated October 21. 1987, summarizing testing that Wyle had performed on 3M tape splices.

Vermont Yankee has since obtained a copy of the Wyle Test Repor?. No. 58316 docu-menting the qualification of the 3M tape splices.

In addition to the above mentioned test report, Vermont Yankee has obtained a second Wyle Te?t a

l Report #17947-01, which further tested 3M splices in various con-figurations.

This test, which satisfies the intent of IEEE 323 1983,

!

included LOCA and main stese line break testing which envelopes the Vermont Yankee application with margin. A QOR revision is in progress to upgrade l

the file as required.

When the additional information is incorporated, l

this QOR will document, in accordance with Division of Operating Reactor j

(DOR) guidelines, that equipment subjected to harsh environmental con-l ditions will perform its intended safety function.

This action will bring Vermont Yankee into full compliance with to CFR 50.49.

This action will be

.

!

completed by July 1, 1988.

3.

Itee 3 involved the qualification of Dings brakes in Limitorque valve

{

operators.

It continues to be Vermont Yankee's position that the qualifi-

>

cation of Limitorque valve actuators equipped with Dings brakes is ade-

{

quately addressed in Vermont Yankee's existing EQ file.

The Certificate of i

Compliance contained in our file states:

"The brake motor supplied with r

special endiation resistant brake coils with materials equivalent to K8110 wou.1d be equivalent to, or superior to, the brake motor included in Limitorque Qualification Report 600194.

The capability of the motor and I

brake coil to withstand radiation only can be supported by Qualification Report 600376A."

Qualification for radiation is clearly. established by the Certificate of Coispliance. Qualification Report 600376A tested an actuator with motor i

which was irradiated to a radiation-dose of 2 x 10 R, which exceeds our i

requirements with s,ignificant margin. During the meeting between NRC and Vermont Yankee on January 26, 1988, the acceptability of vendor documen-l tation to demonstrate qualification was discussed in detail. At that meeting, NRC management concurred that Certificates of Compliance to a test

,

report from a QA-approved vendor are acceptable to link qualification to the certified test report.

In that Certificates of Compliance are the basis of nearly all nucleae documentation, a certificate of Compliance in this instance is as acceptable, if not more so than a letter from a vendor.

Accordingly, it is Vermont Yankee's position that at the time of the inspection, the qualification file clearly established qualification and this ites was in costiliance.

However, in order to fully address Inspection Item 50-271/87-19-06. we will upgrade our file to incorporate the addi-tional informattor,obtained on the material composition of the Vermont Yankee Dings brake and the radiation threshold doses. A QOR revision is in

progress.

This will be completed by May 1, 1944.

4.

This iten involved the qualification of the GE ES-5 terminal blocks.

As

.

stated in the inspection report, Vermont Yankee obtained a memorandue from OE _durjng the audit documenting the similarity of the ES-5 block and the CM-1518 block.

In addition, the EQ file had an overly conservative operating time leading to the auditor's conclusion that the 50119 Limitorque test report did not demonstrate the qualification of the ES-5 block for required insulation resistance. A QOR revision is in progress to document the required operating time of the blocks and to include the sini-larity documentation obtained from GE.

l incorporated, this QOR will document, in accordance with the Livision of Operating Reactor (00R) Ouidelines, that equipment subjected,to harsh environmental conditions will perform its intended safety function.

This l

action will bring Vermont Yankee into full compliance wi,th 10 CFR 50.49.

This will be completed by June 1,1988.

5.

This item involved the qualification of Rome XLPE/PVC cable.

The inspec-tion report states that the peak temperature is not enveloped by actual Rome cable testing and that the file did not contain sufficient information to show similarity to the tests of other manufacturer's cable used by Vermont Yankee to qualify the peak temperature. Vermont Yankee provided additional operability time information during the inspection. The inspec-

.

tion repor,t concludes that based on the data furnished by Vermont Yankee during-end after the inspection, the licensee would be able to establish qualificaitbn.

A QOR revision is in progress to incorporate the infor-nation provided to the NRC.

In addition, Vermont Yankee will perform

,

material and chemical composition testing on selected samples of cables to

'

further establish and document the' similarity of the Rome cable to the

!

cables tested by other manufacturers. When the additional information is

!

incorporated, this QOR will document, in accordance with the Division of

!

Operating Reactor (00R) Guidelines, that equipment subjected to harsh environmental conditions will perform its intended safety function.

This

,

'

action will bring Vermont Yankee into full compliance with 10 CFR 50.49.

This will be completed prior to startup from the next refueling outage.

6.

This item involved the qualification of Lewis PE/PVC cables.

The inspec-tion report states that at the time of the inspection, no valid test report was available in the EQ file to support qualification. During and following the inspection, Vermont Yankee submitted additional information to the NRC to support the qualification of the Lewis cables.

The inspec-

i tion report concludes that based on the additional information provided, the licensee would be able to estabitsh qualification. A QOR revision is in progress to incorporate the information provided to the NRC. When the i

additional information is incorporated, this QOR will document, in accor-dance with the Division of Operating Reactor (DOR) Ouidelines, that

,

!

equipment subjected tu harsh enviromental conditions will perform its

intended safety function.

This action will bring Vermont Yankee into full

.

'

compliance with 10 CFR 50.49.

This will be completed by July 1, 1988.

The Vermont Yankee EQ Program is a dynamic, ongoing program supported by 67

,

i volumes of documentation.

The documentation supporting this program undergoes revision based on new information obtained from a variety of sources including a

j the NRC, utility groups, and lessons learned from other utilities and inspec-tions. This ongoing process will ensure future compliance with NRC rules and regulations precluding future violations.
