Visual Examination of Cable Penetrationn An inspection of both sides of each cable penetration in the control roon and cable spreading room vas perforned. During the last refueling cutage the licensee had pt cpared data shocts which account ed f or every penet rat ion in both rooms and system-atically proceeded to seal then with flamenhstic. According to
.
the licensee all styrofoam uas renoved. The inspector verified

p~
all penet rations were accounted for by the data sheets, and n.
b.
all penetrations had been adequately scaled with flarcrastic.

Fire Detcetion an_d Extinguishing Equipinent During the walk thru the plant the inspector checked the following areas for fire fighting equipment o,..rability and alarms with the following results:
Cabic spreading room - As noted previously_/
this is the only a.
area where tenization detectors are used to ronitor for combustible gases.
They annunciate in the control roon.
Since our last inspection the licensee has purchased the l
required equipient to test the deteetor; prepared Smoke
.
Detector Surveillance Test No. 116, which Oas approved on Septerrher 19, 1975; and sat isf actorily conducted the first semi-annual test on October 28, 1975.
1:evision 1 to the test procedure is being written to include a test of the

Work Cont rol piocedure AdminintratIve C.
t i ol lit ret t ive 4 M'll T.6 revirinn 3 dated August 19, 1975, establishes the requirerent.s for identifying, cont rolling, docunent ing and authorizing all work perf oined within the plant. Work on any c rit leal syst en or component as defined in 4AWI 3.6.1, requires a sccond level of review prior to the r. tart of the work.
1his review requires consideration of work def eral if signi ficant barards or rollibility concerns are involved, and consideration of the training and qualif,1 cations of the personnel to do the work.
Potential industrial hazards, such as combustibic materials, igni tion r.ourc es, e t e ; the need for saf ety monitoring personnel; additional cor.munications equipnent with the control room; provisions f or adequate fin e detection and supprecsf on equipnent; and inspection of the area are covered in the directive.
8.
_ Quality Assurance Surveillance Periodic audit of work request aut horizations are required on at
,
'
least an annual basis.
They are conducted in accordance uit')
ACD 3.7' Rev'ir. ion 2, dated Hay"27,1975 to verify that operating %
'
_
The personnel are cont rolling and authorizing all plant work.
Plant Quallt; Engineer condacted his last audit during the recent refueling outage. The previous audit was denc in !! arch 1975.
So far the audits have consisted of ensuring the WRA forns have been properly filled and approved, but no audit of the work in progress has been perfurned. The Plant Quality Engineer stated he plans to perform "on the job" audits beginning in 1976.
Verification that cahic penetration seal material is nonflammable consists of quality assurance review of purchase orders and receiving ir.spect icns pt f or to raterial being etored. The licensec does not test the naterial to ensure it v.cet s the designated standard, but depends on test performed by independent labo ra t o ries.
9.

The inspec tor reviewed 1)esign Change !' 75-71 which ( overed the installation of additional cabic thru penetration P149. All
,
work van conducted in accordance with administrative controls imposed since August 6, 1975 to assure proper cable penetration seals.
