DOCKETS 50-266 AND 50-301 TECHNICAL EVALUATION OF F7.RE DAMPER TESTS POINT BEACH NUCLEAR PLANTS, UNITS 1 AND 2 In response to Inspection Report 50-266/87007(DRS);
50-301-87007(DRS), which we roccived with your letter dated July 7, 1987, we are providing our Technical Evaluation of Fire Damper Tests at Point Beach Nuclear Plant.
During development of the Technical Evaluation, we determined that a damper closure verification test would be required.
Preparation of a test procedure and scheduling of the test so as not to interfere with the Fall 1987 outage manpower requirements delayed our verification of the Technical Evaluation and submittal for Region III review.
We believe that our submittal of the enclosed Technical Evaluation fulfills our commitment for open item (266/87007-06;301/87007-06), Paragraph 3.c of the Inspection Report.
Please contact us if you have any questions regarding this submittal.

1.0 INTRODUCTION
l During routine safety inspections between February 23 and June 26, 1987, the inspector requested that the licensee provide justification regarding i
the test methodology utilized to demonstrate that fire dampers will close 4
under normal air flow.
Provision of the requested justification was identified as open item 266/87007-06; 301/87007-06 in the July 7, 1987 inspection report.
This Technical Evaluation is prepared in response to the inspector's request.

- 2. 0 PURPOSE I
The purpose of this evaluation is to demonstrate that the methodology used to test fire damper closure under normal air flow provides adequate assurar that the dampers will function as required to maintain fire c

the summary as having been tested under normal air flow conditions.
The sumicary is attached as Table FD-1.
4.0 BASIS In a previous evaluation we determined that it was not practical to expect large multisection dampers to close against normal air flow.
Multisection dampers have been tested statically and a Standing Order has been issued for PBNP operators to shut down ventilation for the affected zone if a fire is detected in fire zones separated by such dampers.
The Fire Damper Test Guidelines dated 03-04-86 were used to test fire dampers under normal air flow.
The guidelines are intended to be generic and do not describe a standard test configuration with specific dimensional tolerances.
However, we believe that a sufficient quantity of dampers were tested ir t conservative air flow configuration to demonstrate that the dampers will operate as intended.
A fire damper is tested one time under normal air flow conditions for design verification.
The initial normal air flow test was conducted on dampers which have been in service between 0 and 17 years without any noticed effect from aging.
Ten percent of the fire dampers listeo in Table FD-1 will be tested statically every 18 months to provide continued damper operability.
Should more than 15% of the dampers tested fail to close, an additional 10% of t,, listed dampers shall be tested until the quantity of failed dampers is less than 15% of the quantity tested.
An engineering review shall also be conducted to evaluate the reasons for damper failure.
r--
5.0 EVALUATION 5.1 Installed Configurations The relative location of components in a ventilation system can affect the outcome of fire damper testing.
The components to be considered are the fan, fire damper, inspection port and ventila-tion grill.
By reviewing fire dampers installed at PBNP, we have determined that seven types of installed contigurations exist.
These configurations are shown on Figure FD-1.
5.2 Flow Characteristics We have evaluated the flow characteristics for each fire damper
' which is expected to close under normal air flow conditions.
These characteristics are listed in Table FO-2.
Since pressure drop across the damper has the major effect on damper closure capability, we conclude that if a damper of a given configuration has been success-fully tested at a specific pressure drop, all dampers of the same configuration which are subject to the same or lesser pressure drops will also be operable under normal air flow conditions.
5.3 Other Effects Several fire dampers have been functionally tested as part of Halon fire suppression system discharge testing.
This testing provides added assurance that these dampers will function as designed.
Where
(
f a datper which is expected to close against normal air flow is in-stalled-in a branch parallel to a multi section damper located in the same fire zone, the damper will operate because the fan which is common to both dampers will be shutdown.
These-effects are also identified in Table FD-2.
5.4 Fi pre FD-1 Evaluation 2
a) lietail (a) depicts fire dampers which are located in the fire barrier without connecting ductwork.
This configuration can be tested from either side of the fire barrier without affecting air flow through the damper.
Therefore we concluded that dampers which are installed in accordance with Detail (a) and which have been tested under normal air flow conditions are operable, b) Detail (b) depicts fire dampers which are located in one branch of a multibranch duct system.
These fire dampers and fire dampers which are installed in the other branches are not exposed to a common fire area.
Therefore, during damper closure an air flow i
path alternate to the affected damper is assured.
During a test i
an open inspection port would increase air flow through the damper in a conservative manner.
A successful test under this condition demonstrates damper operability.
Reaching into the duct to actuate or observe damper closure would obstruct flow in a noncon-servative manner.
For this condition, flow would increase through

Thsrefore, we concluded that dampers which are installed in accordance with Detail (b) are tested equivalent to normal air flow conditions and are operable.
Damper qualification by pressure drop exposure is not applicable to Detail (b) configurations.
c) Detail (c) depicts fire dampers which are located in one branch of a multibranch duct system.
These fire dampers and fire dampers which are installed in the other branches are not exposed to a common fire area.
Therefore during damper closure an air flow path alternate to the affected damper is assured.
During a test an open inspection port would increase air flow through the damper in a conservative manner.

For this condition, flow would increase through the

Therefore, we conclude that i

demonstrates damper operability.
Reaching into the duct to actuate or observe damper closure would obstruct flow in a noncon-servative manner.
The sizes of the duct, inspection port and obstruction are variables which determine the conservatism of air flow during damper testing.
These variables would have to be known and evaluated for individual damper tests in order to achieve a positive determination.
Altornatively, we have reevaluated the actual configuration for individual dampers which are installed in accordance with Detail (d).
The damper and inspection port arrangement for dampers 21 and 22 is shown on Figure FD-2a.
Because of the inspection port locations, these dampers would be tested without obstructing the air flow.
Because of the right angle turn in the normal flow path and the location of the inspection port, any opening during testing would result in conservative additional air flow.
Therefore we conclude that dampers 21 and 22 are operable.
The arrangement for damper 35 is shown on Figure FD-2b.
This damper can also be tested without obstructing the air flow.
Because of the right angle turn in the normal flow path and the location of the inspection port, any opening during testing would result in conservative additional air flow.
Therefore, we conclude that damper 35 is operable.
e) Detail (e) depicts fire dampers which are located upstream of all ventilation openings and inspection ports.
During testing an open inspection port, would increase air flow through the damper in a conservative manner.
A successful test under this condition demonstrates damper operability.
Reaching irito the duct to
actuate or observe closure would obstruct flow in a nonconservative manner.
The sizes of the duct, inspection port and obstruction are variables which determine the conservatism of air flow during damper testing.
These variables would have to be known and eval-uated for individual damper tests in order to achieve a positive determination.
Alternatively we have reevaluated the actual configuration for fire dampers which are installed in accordance with Detail (e).
The damper and inspection port arrangement for damper 34 is shown on Figure FD-2c.
Because of the proximity of the inspection port to the fire damper, this damper can be tested without obstructing the air flow.
Therefore we concluded that damper 34 is operable, f) Detail (f) depicts fire dampers which are located between the inspection port and the ventilation grill upstream of the fan.
The inspect e t port is the only Cuct opening between the damper and the fan.
An open inspection port or an obstruction in the duct would decrease air flow through the damper in a nonconservative manner.
Dampers 31, S2 and 33 are installed in accordance with Detail (f).
The installed configuration is identical for these dampers except for damper size.
The configuration for damper 33 is shown on Figure FE-2d.
The purpose of these fire dampers is to protect the interior of the control building from an exposure fire on the roof.
The dampers are installed below normally closed shut-off dampers which were removed for fire damper installation and testing.
Testing without the normal shutoff damper resistance to flow was conservative.
The fact that these dampers were tested
?
with air flow was a conservative action because the design function of these dampers is to close under a no air flow condi-tion.
Therefore, we concluded that dampers 31, 32 and 33 are operable.
t-While this evaluation has demonstrated the operability of fire dampers listed above, it does not provide justification for future installations.
In the future, installation of fire dampers which must close against air flow should not be installed in accordance l
with detail (f).
i i
g) Detail (g) depcits fire dampers which are located between the inspection port and the ventilation grill down stream from the fan.
The inspection port is the only duct opening between the fan and the damper.
An open inspection port or an obstruction in the duct would decrease air flow through the damper in a nonconservative i
manner.
Dampers 11A, 12A, 13A, 14A, 15A and 16A are installed i
in accordance with detail (g).
The configuration for damper 11A, s
which is exposed to the largest pressure drop requirement is shown on Figure FO-2e.
We have retested this damper with the inspec-tion port opening sealed except for passage of the damper trip wire.
The damper closed successfully.
Therefore we concluded that dampers installed in accordance with detail (g) which must close against an air flow pressure drop less than.264 inches of water are operable.
In the future, fire dampers which must close against higher air flow pressure drops should not be installed in accordance with detail (g).

6.0 CONCLUSION
i This Technical Evaluation demonstrates that fire dampers installed at PBNP prior to January 1, 1988, which are expected to close against normal 3
air flow, have been tested in a manner which provides adequate assurance that the dampers will operate as required.
Fire dampers which are installed after January 1,1988 shall be installed in accordanco with Figures FD-2a, b or e or shall be tested in accordance with Operating Instruction 01-88, Fire Dampers.
