Review of the methods utilized by NSC to calculate the mass and energy release data has revealed the following concern. The steam generators were each modeled as one control vc;ume. This technique does not model the steam separator located in the steam generator.

The. effect of neglecting the steam separator in model will significantly affect'the amount of entrained liquid that is calculated in the steam generator effluent.

7. Significance of Concern:

Safety-related equipment located outside containment affected by a main steam line break which must function in a severe environment may be exposed to greater temperatures than reported.

Auxiliary Feedwater System (AFW) Equipment.

6. Description of Concern:

Review of the methods utilized, by Nuclear Services Corporation (NSC), to calculate the pressure and temperature transients in area GE at elevation 115'-0", due to a main steam line rupture in area GW at elevation 115'-0", revealed the following:

1. Enthalpy values utilized to determine the energy rates into area GE were developed from the CONTEMPT computer prcgram output that calculated the environments in area GW at elevation 115'-0". The enthalpy values developed from the CONT MPT computer program output were too low due to the accumulat on of-air in area GW (Refer to Error Report 8001).

2. The method utilized to calculate the mass discharge data into area GE and the one node model developed to analyze the environments in area GE will result in the calculation of pressure and temperature transients which are too low. The NSC method of calculating the mass discharge data into- area GE considered only flow from area GW elevation 115'-0" and the model developed to calculate the environments for area GE elevation 115'-0" assumed all vents out of the area exhausted to atmosphere except the vent into area GW. The effects of adjacent compartments on the environments in area GE elevation 115'-0" were neglected.

7. Significance of Concern:

Safety-related equipment outside containment will experience ligher temperature and pressure environments than reported, as listed below:

A. The equilibrium temperature calcglated in area GE0 at elevation 115'-0" may be approximately 300 F instead of 212 F calculated by NSC.

8. The peak pressure in area GE at elevation 115 '-0" may be approximately 20 psia instead of 17 psia calculated by NSC.

C. The door between GE at elevation 115'-0" and the Fuel Handling Building, which is assumed closed, may exceed its design pressure of 2 psid.

Safety-relamd equipment outside containment which must be located ab)ve flood levels or protected against submergence.

6. Description of Concern:

Review of the flooding in area GW due to a feedwater line rupture revealed the following nonconservative assumptions:

1. The inventory available for release from the steam generator considered only the liquid mass above the feedwater sparger ring (inletpipe). Therefore only approximately 25,000 lbm frcm the steam generator that contains 153,000~lbm was considered for calculation of the maximum ficod height. -

2. Auxiliary feedwater flow out of the rupture pipe was not considered.

Assumptions concerning steam generator water inventory and auxiliary feedwater addition could affect calculation of flooding heights.

PGandE Completion Sheet, IDVP File No. 8042, signed 12-15-82 transmitted via DCVP-SWEC-271 dated 12-16-82.

SWEC has reviewed the PGandE documentation referenced above. The PGandE response is acceptable based on the following. The circuits are not mutu' a lly redundant even though they are two different color coded Class IE circuits, and therefore do not require separation.

Failure of a panel (eg. PY11) fed from the gray backup power source disables only that panel (PY11), because. breakers for the b'ackup gray power source in the other three panels are normally open. The breaker in BTH101 isolates the fault from Bus 1G. Therefore a comon mode failure would not result from the failure of the panel.

6. Program Resolution is:

The IDVP con, curs with the resolution based on the following:

A. The circuits are not mutually redundant B. Any failure of a panel will be isolated by circuit breakers.

Therefore this item will be closed.

5. Resolution based on the following documentation:
PGandE Completion Sheet, IDVP File No. 8015, signed 12-16-82 transmitted via DCVP-SWEC-271 dated 12-16-82.
SWEC has reviewed the PGandE documentation referenced above. The PGandE response is acceptable based on the following. Two different power circuits to one device are not mutually redundant circuits and do not require separation. As a result o'f the protective devices used, failure at the control circuit for Diesel Generator 11 results in the loss of Diesel Generator 11, but because of breaker trips, does not disable DC panels, 5012 and SD13, nor Diesel Generators 12 and 13. A similar situation exists for the control circui.ts for Diesel Gene ators 12 and 13.
i
6. Program Resolution is:
The IDVP concurs with.the resolution based on the following:
A. The circuits are not mutually redundant B. Protective devices isolate control panels and the Diesel Generators resulting in availability of redundant generating capability in the event of a single failure.
Therefore this item will be closed.

3. O&te Reported to PG&E 830209
4. Scheduled for TES Semimonthly Report No. February
5. Resolution based on the following documentation:
DCVP-SWEC-260 dated December 1,1982 from PGandE contained PGanJE's resolution and completion package for File No. 8053, Revision 1.
PGandE responded 'that the incorrect design class designation for radiation monitors RM 51, 52, 53, 54 was attributable to a drafting error which will be corrected on a subsequent drawing issue. They further stated that in addition to being purchased as safety-related devices, the instruments have been installed, powered, and otherwise ,
treated as Class IE devices. To substantiate this, DCN DCO-E-C-679 '
and Drawing 437970 Revision 8 were submitted.
SWEC has reviewed the PGandE documentation referenced above. The l DCN which incorporated the radiation monitiors into the CRVP system l was identified as safety-related. The drawings by the electrical group which show the radiation monitors as Class IE were issued prior to the radiation monitor instrument schematic. Other - than on instrument schematic 102931, sheet 12, Revision 7, there is no indication that these devices were treated other than Design Class I. Therefore, PGandE's response is satisf actory. The radiation monitors were purchased and installed to Design Class I criteria.
6. Program Rest lution is:
IDVP concurs with the above resolution, however since a drafting error was revealed this item is reclassified as a Deviation. This item will be closed if no modifications are required.

6. Description of Concern:
Documentation is required to verify the capability of the motors
, listed to start and perform their function with 80% rated voltage (368V for 460V motors and 3200V for 4KV motors) applied at their
~~
terminals. (The 80% motor ' starting commitment was stated in PGandE letter to NRC dated October 3,1977, response to question 1-C).
7. Significance of Concern:
Motors required to start at voltages less than rated starting voltage, may require excessive time to accelerate to full load speed. This may cause over current trip of protective relays.
8. Recomendation :
DCP to provide documentation verifying motor's capability to start and accelerate to full-load speed at 80% of rated voltage.
Documentation should be the purchase specification specifying 80%
start capability and a statement from vendor showing his compliance with the purchase specification.
