Fire Protection - Permanent Plant
a.
Commitments i
The inspector reviewed the licensee's action on the fire protection commitments made to the NRC. The NRC Fire Protection Safety Evaluation l
Report included in Section 9.5 of the facility Safety Evaluation Report i
(SER) dated February 1981 and the licensee's Fire Protection Evaluation Report (FPER) including Revisions 1 - 6 were used in this review. A l
number of discrepancies were noted between the fire protection features l
identified in the SER, the commitments in the FPER and tne features actually being provided at the pirnt.
These included the following items:
(1) Control valves are not to be provided for the fire hydrant laterals (SER, page 9-15).
(2)
Electric power supply to electric fire pump does not conform to NFPA 20, Centrifugal Fire Pumps (SER, page 9-15).

(13) An automatic suppression system and a one-hour fire rated barrier for one of the divisions where the recundant circuits or equipment are separated horizontally by less than 20 feet are not to.be provided; however, one of the redundant circuits will be enclosed by a 1-h-hour fim rated barrier (SER, page 9-22).
The i k um hn ident.ified the:c ita.:, has contacted NRC/NRR and requested a meeting to resolve these discrepancies.
This item is identified as Unresolved Item (395/81-13-01), Discrepancies between j.
fire protection features provided and those listed in the SER.
The
!
inspector advised the licensee that this item should -receive prompt l
attention and must be resolved prior to licensing.

Fire Protection Systems and Features l
A tour of the plant was made by the inspector to inspect the following fire protection features:
.
(1)
Fire Dampers l
Practically all of the fire dampers have been installed The
.
'
following dampers were inspected and found to be satisfactorily.

- NOTE:
- Not safety-related.
t
'
-Documentation was provided for the QC inspecticn of the safety-related dompers. Hot t er, QC documentation could not - be located on the non-safety-related dampers. The licensee's response to Question 421.77 in the FSAR (Amendment 16 dated November 1979) stated that the QA program is ap). led only to the installation ar:d preoperational testing of fire protection equipment. It is not clear to what extend the QA/QC program is to be applied to items which were completed prior to the current fire protection QA program commitment.
This item will be further evaluated during a subsequent ~ NRC inspection.
Refer to Inspector Followup Item (395/81-13-03) in paragraph 5.b.(5).
.
(2)
Fire Doors
.
Th' licensee estimated that the installations of the fire doors in e
various locations throughout the plant was approximately 90*s complete with the installation of builders hardware and final door
' alignment being the primary outstanding items.
The licensee stated that a final QC inspection to vert fy correct installation is to be made when the door insi.allations are complete. This will be reviewed during a subsequent NRC inspection.
(3)
Fire Resistant Coatings The structural steel in all areas of the plant such as the control building which was required to be coated with a fire resistant coating has been coated. The initial work was inspected by QC using Procedure CF-27, Spray Fireproofing. The inspector reviewed the QC inspection records for the following areas:
Location QC Inspection '
Control Bldg /Rocm 36-08 2/28/78 Control Bldg / Room 48-01 2/12/78 The inspection data sheets were not approved by the QC coating supervisor.
The licensee stated that portions of the coating materials had been removed from some areas during the construction operations for the installation of hangers, supports, es.c. and that these areas were presently being recoated.
All of the_se areas are to be reinspected by QC prior to final acceptance by QC:
and the plant.

(4) Sprinkler Systems The installation of the sprinkler systems which were incorporated as part of the original plant design were essentially complete.
The sprinkler systems were inspected by QC to verify that the installation was in accordance with the construction documents.
The inspector reviewed the -QC inspection documents for the following systems and found this data to b2 satisfactory.
System No.
Location QC Inspection FS 09 Diesel Generator Bldg.
3/26/79 FC 22 Fire Pump Bldg.
3/26/79 F5 24 Service Water Pump House 3/3/81 FS 20 Cable Spreading Room 5/15/80 The hydrostatic pressure test and flushing test data were not
'
reviewed during this inspection.
(5)
Fire Alarm Systems There are two fire alarm systems provided for the plant.
One system is a standard fire alarm system which is designed to meet
-
the provisions of NFPA-720. Most of the fire detectors located in the safety-related areas of the plant are connected to this alarm system. The second fire clarm system is actually part of the HVAC alarn system but the FPER takes credit for this system in some i
areas.
Fire detectors and high temperature thermostats in the i
HVAC systems are connected in'to this system. This system does nat meet tne provisions of NFPA-720 for a standard fire alarm system
'
since most of the equipment is rot listed or approved by a recognized testing organization for fire protection application and the power and alarm circuits are not electrically supervised.
This item is part of Unresolved Item (395/81-13-01) in sbove =
paragraph 5.a.
,
The fire alarm systemt are equired by Procedure EF-11, Inspectica of Installation of the Fire Service System, to be inspected by the QC
organization. QC inspection documentation is provided for the conduit, tray 'and cable termination for the detector units in s' fety-related a
areas. However, documentation is not provided for the installanon of
,
,
the main fire alarm control panels and for the location and spacing of
'
each detector unit in safety-related areas, i.e., verification that the detectors wera properly lc:ated was not made. The licensee's response to FSAo question 421.77 states that the QA program for fire protection is part of the overall QA program and installation, testing and
' subsequent operations are processed similar to those utilized for

safety-rela'ted work. Procedura EF-11 was prepared to provide instruc-tions for the QC inspectionsLof the electrical ' equipment in the Fire Service Systems. Paragraph 1 of this procedure states that " electrical
-
,
,
QC will inspect fire service related equipment for identifiestion, location, physical' integrity and-leveling and plumbness". Paragraph
_
2, 3, 4 and 5 of this procedure states that DC will inspect and verify proper cable installation and termination wi*.h documentation of there inspections to ba made on "FQCP" forens. The lack 'of documentation to indicate that these inspections wece conducted on ail portions of the fire alarm system is a failure to-meet a commitment to the NRC. This item is identified as Caiation Item (395/81-13-02), Inadequate QC documentation of the fire alarm system installation.
.
T% licensee aavised the inspector by telep.t.ne on June 1,1981, that GC c,ocumentation had been located on the fire detection equipment installed as part of the HVAC control panel r.ich was installed by another contractor. This data will be revie>;ed during a subsequent NRC inspection and is identified as Inspector Followup Item (395/81-13-03),
,
Review of QC documentation for HVAC fire protection equipment.
Except as noted above, within the areas examined, no violations or additic9a1 deviations were_ identified.
