Inspection
Report No. 50-387/85-34
and 50-388/85-30
This refers to the routine safety inspection
conducted
by Mr. F. Paulitz of
this office on November 4-8,
1985, at the Susquehanna
Steam Electric Station,
Units
1 and 2, Berwick, Pennsylvania,
of activities authorized
by
NRC License
Nos.
NPF-14 and
and to the discussions
of our findings held by
Mr. Paulitz with Mr. T. Crimmins and other
members of your staff at the con-
clusion of the inspection.
Areas
examined during this inspection
are described
in the
NRC Region I
Inspection
Report which is enclosed with this letter.
Within these
areas,
the
inspection consisted
of selective
examinations of procedures
and representative
records,
interviews with personnel,
and observations
by the inspector.
Within the scope of this inspection,
no violations were observed.
No reply to this letter is required.
Your cooperation with us in this matter
is appreciated.

KV cable,

noted
above

there
are

this is 958 amperes.
The cables

design
Calculate
voltage drop
The correction factor for conductor temperature
of 90 degree
C to be applied
to the
25 degree
C d-c ohmic resistance
is 1.256
0.01079R
x 1.256
= 0.01355
ohms per
1000 feet corrected
to 90 degree
C
The total
Impedance
Z = Square
root of (R squared
+ x squared)
= 0.03530
ohms
per
1000 feet
Since the circuit length is 700 feet, this is further corrected to (0.03530
x
700 divided by 1000)
= 0.02471
ohms
Since there are
two circuits per phase,
this is further reduced to (0.02471
divided by 2) = 0.01235 total
ohms
The voltage drop is equal
to I x Z = 0.01235
ohms
x 790 amperes
= 9.76 volts
This represents
6% of the
maximum voltage drop between
the 4, 160 volt bus
and
the
4000 volt nominal
equipment rating
CONCLUSION
The inspector did not identify any deficiencies with respect
to the cable size
selected
by the licensee
considering
the cable ampacity
and voltage drop
