Licensee Action on Previous Inspection Findinas

(0 pen) Deviation 50-313/8215-03; 50-368/8212-02:

This deviation identified

electrical conduit installations, which had unsealed air gaps external to

the conduits, penetrating the lintels above fire doors 46, 259, 260,

and 271.

The NRC inspector determined that the air gaps have been

sealed.

However, subsequent to the original inspection, a generic issue

was raised concerning modifications to UL rated fire door assembifes.

There are cases where UL has a110wed the ratin0 to stand where minor

modifications have occurred if they are inspected by a UL representative

and it is documented that the existing condition is acceptable.

The

Ilconsee has determined that fire Door 46 is no longer in a Technical

Specification fire barrier and should be deleted from this item.

The

licensen informed the NRC inspector that UL representativos have reviewed

the remaining door configurations and deemed them acceptable, however,

supporting documentation from UL was not available.

Pending receipt and

availability for review in a future inspection, this deviation will remain

open.

(Closed) Open Item 50 313/0215-04; $0-368/8212 03:

This item was open

pending resolution of the followin0 specific items and completion of the

licensee's review for 10 CFR 50, Appendix R, Item !!! 0:

.

3

a.

Barrier material not yet accepted as a "3-hour barrier."

b.

Terminal boxes not covered by barrier material in conduit runs

already covered.

c.

Conduit above door 57 only covered for half its length.

The licensee has completed the 10 CFR 50, Appendix R, review and is now

resolving exemption requests.

Appendix R compliance inspection is to be

scheduled at a later date.

Specific item resolution was inspected and it was found that the

installation of barrier material had been significantly redefined.

The

separation criteria requires only a "1-hour barrier" and this has been

installed on conduits with cables of concern and is the Hemyc Barrier

System.

Terminal boxes in the conduit runs were covered.

The conduit

above Door 57 was determined not to contain any cables of concern.

Adequacy of the review and determination of the cables of concern will

be addressed and inspected during the inspection for Appendix R

compliance.

This item is closed.

(0pon) Open Item 50-313/8215-05:

Thic item is open pending final action

by NRR on the final test results for cable penetration fire stop design.

This item remains open.

(Closed) Open Item 50-368/8212-04:

This item was open pending

determination by the Itcensee that Motor Control Center 2051 would not be

subject to flooding because of the location of the water suppression

system spray head.

The NRC inspector determined that the licensee has

installed a deflector spray shield between the spray head and the panel.

It has also been confirmed that the panel accesses are all rubber

gasketed.

This item is closed.

(Closed) Open Item 50-368/0212-05:

This item was open pending repair or

replacement of damaged fire retardant board installed on a cable tray in

the electrical equfpment room.

After the Appendix R, evaluation it was

found that separation was met and that it was not necessary to take

credit for the board.

This item is closed.

(Closed) Vlointion 50-368/8325-02:

This violation identified that two

designated fire doors. Doors 267 and 340, had gaps from door to floor in

excess of 3/4-inch and that no fire watches were estab11shed.

The

licensens immediate corroative action, establishing a fire watch and

initiating a station wide inspection of all fire doors is considered

adequate.

Doors 267 and 340 now have air gaps of less than 3/4-inch.

!

Other doors identified in LERs 50 313/83-023 and 50 360/83 045 have also

i

been corrected.

The air gap criteria is now in Surveillanco Procedure

j

1300.05 and is checked every 18 months.

This item la closed.

Licensee Event Report (LER) Followup (Unit I and 2)

Through direct observation, discussions with licensee personnel, and

review of records, the following fire protection / fire prevention related

LERs were reviewed to determine that reportability requirements were

fulfilled, immediate corrective action was accomplished, and corrective

action to prevent recurrence has been accomplished.

Unit 1

LER 83-021 dealt with the discovory that cross wiring had occurred on two

deluge valves.

The specific problem was corrected and similar

installations were checked for the same problem.

This LER is considered

closed.

LERs82-018 and 83-023 dealt with degradation of fire barriers and

resulted in an extensive walkdown of all fire barriers, identification

and correction of all de0raded conditions.

The licensee is presently

conducting the first 18-month surveillance of fire barriers since the

implementation of the extensive review program.

Subsequent inspections

will review the results of corrective actions taken.

The LERs are

considered closed.

Unit 2

i

i

LERs81-042, 82-039,83-004, 83-008,83-021, 83-026,83-032,

i

83-042,83-045, 84-015, and 84-017 dealt with degradation of fire

barriers and resulted in an extensive walkdown of all fire barriers,

identification and correction of all degraded conditions.

The licensee

will conduct the first 18-month surveillance of fire barriers following

this extensive review program after completion of the Unti 1

surveillance.

Adequacy of corrective actions will be reviewed in future

inspections.

These LENS are considered closed.

LER 82-029 dealt with the pulling of cable through a fire damper

openin0

Immediate and long term corrective action was adequate.

This

LER is considered closed.

LER 83-033 dealt with the floor to door air gap problem.

This item is

addressed in detall in paragraph 2 of this report under Violation

50 368/8325 02.

This LER la considered closed.

LER 83 035 dealt with the potentini for flooding in certain areas

protected by deluge systems because of inadequate drain capacity.

This

item is still under review by the Itconsee's engineering organlantion.

LER 83 037 dealt with the penetration of fire door lintels by conduit.

This item was addressed in detail in paragraph 2 of this report under

Deviation 50 368/8212 02.

LER 84-016 dealt with the discovery of an inoperable fire damper.

The

licensee's investigation of this item is continuing.

LER 84-029 dealt with a fire door automatic closure mechanism that failed

to work.

The licensee has increased the frequency of inspection of high

usage doors.

This LER is considered closed.

4.

Fire Protection / Prevention Program Implementation

This inspection was conducted to determined that the licensee is

implementing a program for fire protection and prevention that is in

conformance with regulatory requirements and industry guides and

standards.

l

The NRC inspector toured accessible areas of the plant site for general

area condition, work activities in progress, and visual condition

of fire protection systems and equipment.

It was found that combustible

materials, flammable and combustible liquid and gas usage is restricted or

properly controlled in areas containing safety-related equipment and

components.

There were no welding, cutting, or use of open flame ignition sources

found in the areas toured.

General housekeeping conditions were found to

be very good.

There were no construction or maintenance activities in

progress in the toured areas.

Fire protection systems and equipment installed for protection of safety

related areas were found to be functional, and tested in accordance with

the requirements specified in the Technical Specifications.

Fire brigade

equipment including emergency breatising apparatus was found to be

properly stored and maintained.

However, the isolation valve, 2FS-106, for the pre-action valve for

Corridor 2139 suppression system was found shut.

Discussion with the

licensee's representative confirmed that this valve was shut because the

exemption request to delete the requirement for a suppression systea for

Corridor 2139 had been granted.

Subsequent review shows that

Procedure 2203.09, Revision 0, dated June 26, 1981, " Fire Protection

System Annunciator Corrective Action," in Attachment A, 1-5-5 " Corridor by

Emergency Control Room Chillers Zone Module" still assumes that the

pre-action valve is available for remote operation in the control room.

This procedure should have been revised to reflect the system status

i

change and insure the operator had an operable action for this area.

Failure to maintain procedures covering activities in the area of fire

protection program implementation is an apparent violation.

(50-368/8516-01)

The NRC inspector also reviewed fire brigade training and drill records

and reviewed the current roster of qualified brigade members.

TF9

records were in order and confirmed that training and drills are being

conducted at the specified intervals.
