Licensee Action on Previous Inspection Findings a.
(Closed) Deviation Item (369/79-34-01 and 370/79-20-01); Inadequate fire protection for QA records storage room. This item was closed by Report Nos. 50-369/80-10 and 50-370/80-06.
b.
(Closed) Unresolved Item (369/79-34-02 and 370/79-20-02); Substandard
'
fire pump installation.
NRR memorandum for W. Laudan, IE/HQ from V. A. Moore, NRR/ DSS dated January 15, 1980, advised that the existing fire pump installation at McGuire was acceptable. Therefore, this item is closed.
c.
(Closed) Inspection Followup Item (369/79-34-03 and 370/79-20-07);
Repairs to fire pump No. A.
The electric motor for pump No. A has been repaired and reinstalled, also, the missing automatic air release valve for this pump has been replaced. This item is closed.
d.
(Closed) Deviation Item (369/79-34-04 and 370/79-20-04); Inadequate
.
procedure for flushing fire protection piping systems. The licensee's letter from W. O. Parker, Jr.,
to James P. O'Reilly, Director, NRC
_ _

-.
_,
.

.
-2-
.
Region II dated November 8,1979 states that tests conducted on portions of the fire protection piping systems revealed that the flushing flow rates were well above the flow demand of the systems which satisfied the intent of the National Fire Protection Association (NFPA) standards.
Also, the systems are to be flushed at the design rate during the pre-operational tests to be conducted on the plant systems. Based on these comments, this item is closed.
e.
(0 pen) Deviation Item (369/79-34-05 and 370/79-20-05); Substandard sprinkler system installation for Unit 1 battery room. The upright type sprinkler heads have been replaced with pendent type heads and heat shields have been provided for each sprinkler head; however, sprinkler protection has not been provided beneath the cable trays located between column lines 53AA/54AA and 53BB/54BB. The licensee advised that a connitment was not made to provide sprinkler protection in this area. This item is being forwarded to NRR for evaluation and comment.
Also, the arrangement of the water flow inspector's test connection device does not meet the provisions of NFPA-13 and is included in the list of code discrepancies of Paragraph 5.b.(2) of
'
this report. This item remains open pending further review.
f.
(Closed) Unresolve - Item (369/79-34-06 and 370/79-20-06); Substandard water spray fire protection system for cable spreading rooms. NRR memorandum for W. Laudan, IE/HQ from V. A. Moore, NRR/ DSS of January 15, 1980 advised that the examples of hTPA code discrepancies for these systems were not pertinent since the plant can be shutdown independently of the cable spreading rooms. However, the code discrepancy for the i
i type water flow alarm is considered a valid discrepancy. This item is considered an example of the alarm device discrepancy of Paragraph 5.b.(2). Therefore, this item is closed.
g.
(Closed) Unresolved Item (369/79-34-07 and 370/79-20-07); Substandard fire protection piping system to auxiliary building. NRR memorandum for G. W. Reinmuth, IE/HQ from R. A. Birkel of NRR dated February 12, 1980 stated that the arrangement of the water supply to the auxiliary and reactor buildings fire protection systems had been evaluated and l
found acceptable. Therefore, this item is closed.
It must be pointed out, however, that based on calculations using the Williams-Hazen Hydraulic Calculation Formula of:
4.52 x (flow in gpm)I'O Friction loss = (Roughness Coefficient) x (pipe diameter) g
,
produces a friction loss in the by pass around each deluge valve of 90 psi with 230 gpm flowing and 70 psi with 200 gpm flowing. In other words, based on a static pressure of 130 psi at grade, the by pass piping for each deluge valve will not provide a sufficient flow to meet the demand of 435 gpm at 61 psi for the largest automatic sprinkler
-
system (Room 806 - component cooling pumps) in the auxiliary building.

(Closed) Unresolved Item (369/79-34-08 and 370/79-20-08); Inadequate QA procedure for auditing fire protection system installations. This item was closed by Report Nos. 50-369/80-10 and 50-370/80-06.

Unresolved Item Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviations.
New unresolved items identified during this inspection are discussed in paragraph 5.b. (10).

b.
Findings:
Additional information on the "Open" items in Paragraph 5.a is listed l
below. The below listed numbers correspond to the numbered items in l
pr.ragraph 5.a.
(1) The licensee is currently providing additional fire detectors in several areas of the reactor building. Presently, only ionization detectors are provided within the annulus area whereas Table
.
D-1.7 in the licensee's FPR states that both ionization and rate of rise type detectors will be provided in this area. Also, fire l
,

.
detectors are not provided over a number of cable trays inside the crane wall whereas Table D-1.7 of the FPR states that detectors will be provided over these cable trays. This item is identified as Inspector Followup Item (369/80-11-03 and 370/80-07-03), addi-tional fire detectors for reactor building and diesel generator building, and will be reviewed during a subsequent NRC inspection.
(2) The sprinkler systems provided do not fully meet the criteria of National Fire Protection Association Standard No. 13 (NFPA-13),
Sprinkler Systems or NFPA-15, Water Spray Fixed Systems, due to the following:
(a) Pendent sprinkler heads are installed as upright heads in at least one location.
Section 3-16.2 of NFPA-13 requires sprinkler to be installed to meet their distinct design criteria.
(b) Ordinary degree sprinkler heads are installed in a number of areas where the temperature in the area dictates that higher degree rated sprinklers must be installed. In several areas the construction drawing require 212 degree F rated sprinklers
!
but 165 degrees F rated sprinkler have been installed. The required temperature rating and applications for sprinkler heads are included in section 3-16.6 of NFPA-13.
(c) Portions of the sprinkler systems utilize short sections of 1/2 inch diameter pipe. Typical examples are the systems for the annulus area and the reactor coolant pumps. Sections 3-5, 3-6, 3-7, and 7-1.1.2 of NFPA-13 and 4-9.1 of NFPA-15 specifically prohibit the use of piping smaller than one-inch in diameter.
)
(d) Serious obstruction to proper discharge of water from the sprinkler systems exist in a number of areas due to instal-
'
lation of cable trays, piping, ducts, structural supports, etc., beneath the sprinkler systems.
Section 4 of hTPA-13 gives specific guidance as to the requirements that must be
adhered to, to assure minimum interference or obstruction from proper discharge by the system in the event of fire.
(e) Water flow alarm devices are either not provided or if provided are not equipped with proper type test devices.
Also, dry systems are provided with paddle type flow alarm
,
indicators which are specifically prohibited by Section 3-17.3.4 of NFPA-13.
The criteria for water flow alarm devices is located in Sections 3-9.1.2, Figure A-3-9.1.2, 3-17.3, 3-17.4 and 3-17.6 of NFPA-13.
(f) Some control and sectional valves in the fire protection
-
piping systems are not indicating type valves as required by l
Section 3-14 of NFPA-13.

Section E.3.(c) of the licensee's FPR states that the sprink-1er systems conform to the provisions of NFPA-13 and NFPA-15.
The above examples of nonconformance to the applicable NFPA codes is a failure to meet a commitment to the NRC and is identified as Deviation Item (369/80-11-01, 370/80-07-01),
substandard sprinkler system installations. The above code discrepancies are only examples. It is probable that addi-tional discrepancies exist.
(7B) The sprinkler heads in this area are located approximately 3 feet below the ceiling whereas Section 4-3 of NTPA-13 requires this distance not to exceed 12-inches. Refer to item (2) above.
(9) Emergency 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> fixed battery light units are not provided for this area.

This discrepancy is being evaluated by the licensee and is identified as Unresolved Item (369/80-11-02) and 370/80-07-02), battery powered emergency lighting requirements for safety-related pumps, and will be revicwed during a subsequent NRC inspection.
(11) Refer to above item (2) for details.
(19B) Emergency 8 ho r battery lights are not provided for this area as stated by Appendix C page C-17 of the FPR.
This is another example of the Unresolved Item identified in above item (9).
(22) The diesel generator rooms are not presently provided with ionization type fire detectors. This item is another example of the unresolved item of above item (1).
