CATAWBA NUCLEAR STATION
_ Report Number: 413-414/84-16, Supplement I Report Date: August 31, 1984 Facility: Catawba Nuclear Station Units 1 and 2 IDENTIFICATION OF DEFICIENCY: Unconsidered effects of superheated steam generated by steam generator for Main Steam Line Break analysis results in increased doghouse temperatures outside containment. This could possibly preclude safety related components from performing their intended safety function. The potential deficiency was initially identified May 11, 1984.
Initial Report: On June 8,1984, Mr. Kerry Landis, NRC Region II, Atlanta, Georgia, was notified by telephone of the subject deficiency by L. M. Coggins and R. R. Weidler of Duke Power Company, Charlotte, N. C. 28242. Subsequently, deficiency report (413-414/84- 16) 'as submitted on July 9,1984.
Component and/or Supplier: Duke Power Company is responsible for the doghouse environmenta'l analysis. The MSLB analysis is accomplished utilizing input information supplied by '.'estinghouse Electric Corporation, Water Reactor Division.
Description of Deficiency: Revised information has been received from Westinghouse giving mass / energy release rates for a Main Steam Line Break (MSLB) inside containment. The original Westinghouse information indicated a saturated steam condition from the steam generators; however, revised information identifies steam generator tube uncovery and the formation of superheated steam.
Duke Power had previously assumed the same saturated steam condition for a MSLB in the doghouses located outside containment. Equipment important to safety for mitigating an MSLB in the doghouses has been identified (see list in corrective action below). Environmental qualification parameters for the doghouses are currently based on original analysis results of 330 F.
Utilizing the new data from Westinghouse, revised Duke Power environmental analysis with superheated steam conditions indicates gn increase in doghouse temperature from the present 3300F parameter to a 440 F maximum doghouse temperature, ANALYSIS OF SAFETY IMPLICATIONS: A study has been conducted by Duke Power .,
with assistance from Westinghouse to determine if subjecting safety related components to temperatures higher than the qualification basis of 3300F could possibly preclude components from performing their intended safety functions following a postulated MSLB in eitMr doghouse. The results of these studies are presented under " Corrective Action", below.
Corrective Action: The analyses perfr.rmed by Duke Power Company and Westinghouse demonstrate that no required safety related components are precluded from performing their safety function prior to the on-set of adverse temperature effects and, therefore, no safety implications exist to prevent safe shutdown of the plant. Safety related equipment potentially impacted by MSLB tempera-tures higher than the equipment qualification envelopes identified in report 413-414/84-161have been addressed in this report. See Attachment 1.
, , , a
' The following is a description of the results of the analysis work perfonned to resolve this deficiency. Westinghouse has performed a steamline break analysis for a spectrum of break sizes and power levels (full power, 70%,
~
30% and 0%) to determine associated protection system actuation times and predicted superheat initiation times. The analysis was performed using safety analysis assumptions of initial conditions ~ and protection system time responses to provide a conservatively early prediction of steam generator tube bundle uncovery and, therefore, the earliest superheat initiation time. This analysis was used to verify that required safety system actuations (in the doghouse) will be completed before adverse temperature effects due to increased doghouse temperatures occur. In the case of certain breaks (see discussion under "Small Break"), tube bundle uncovery does not occur, and consequently no superheat is initiated.
Results of the Westinghouse analysis are as described in the following paragraphs:
Large Break Typical response to large breaks approximately 0.5 ft.2 and greater (power level affects the cut-off of break size) in the doghouse main steam line will be as follows :
- Reactor trip will occur on overpower AT, low steam line pressure, or low steam generator level.
- Main feedwater isolation valve (MFIV) closure will occur due to reactor trip and low Tavg or safety injection signal. See Attachment 1 for a list of other valves that close on feedwater isolation signal.
- Safety injection will be initiated upon receipt of a low pressurizer pressure signal or low steam line pressure signal.
- The motor driven auxiliary feedwater pumps (MDAFP's) will start upon receipt of the safety injection signal or low-low steam generator level.
- The turbine driven auxiliary feedwater pump (TDAFP) is not required for this break since one MDAM can supply adequate flow if the other MDAFP fails to start.
- Low steam pressure in the faulted steam generator causes main steam isolation valve (MSIV) closure. See Attachment 1 for a list of other valves that close on main steam isolation signal, i All the above functions will occur before the temperature in the Doghouse exceeds equipment qualification temperatures. Isolation of auxiliary feed-water to the faulted steam generator may be accomplished by the operator by closing the motor operated valves located in the doghouse, or by closing the control valves from the control room or manual isolation valves located in the auxiliary feedwater pump room.

- ,: , .1 Intermediate Break '
~ For intermediate breaks, approximately .0.3 ft.2 to. 0.5 ft.2 (power level
>affects the range of break sizes), response will be as follows: .
- Reactor trip will occur on low-low steam generator level. Note that all
. steam generators will approach low-low level at approximately' the same time.
- MDAFP's will start upon receipt of first low-low level signal. TDAFP
- will start upon receipt of the second low-low . level signal .
EMFIV closure will occur due to reactor trip and low Tavg.
- Safety injection will occur. due to . low pressurizer pressure.
- Main steam isolation will occur due.to low steam line pressure; this may actually happen after tube uncovery. However, Duke analysis using revised Westinghouse mass-energy release data shows that main steam isolation will . occur before temperatures -in the higher elevations of the doghouses (where the main steam isolation valves are located) exceed the current equipment qualification parameter of 3300F.
Faulted steam generator. isolation is accomplished as described for the large break.
Small Break Depending on exact br approximately 0.3 ft.gak size and power level, small break (less than) response wil or as follows. For a garrow band of break sizes within this category (approxi-mately 0.1 to 0.2 ft.'), the feedwater control system will automatically increase feedwater flow and prevent reactor trip and tube uncovery. Blowdown through the break will be limited to saturated conditions. The operator will initiate-reactor trip and position valves from the control room. Faulted steam generator isolation is accomplished as described for the large break.
All Breaks The only post-accident monitoring instruments located in the doghouse are the auxiliary feedwater flow transmitters, which are not required to mitigate the consequences of a doghouse MSLB. Although these may fail under this environment, post-accident monitoring of the auxiliary feedwater function can be accomplished by the steam generator level transmitters which will not
-be affected by a steamline break in the doghouse.
Water level instrumentation in the doghouses is not required to function in the event of a doghouse MSLB.
-Duke has also analyzed the potential consequences if the temperature in the doghouses exceeds the qualification temperature after the equipment has performed its. intended safety functions described above. The analysis has shown.that, because of electrical circuit design features such as isolation, E
interlocks, and protective devices, valves will not reposition after actuation.

A study has also been conducted to determine the effects of the MSLB on structural steel and concrete in the doghouses. For the resulting tempera-ture time history in the doghouse compartments, all reinforced concrete structural members would continue to perform their intended function.
Structural and miscellaneous steel used to support grating for personnel access could experience some local instability or local yielding, but would not collapse. Also, there will be no adverse effects on pipe rupture device or support / restraint structural steel in the doghouses. The connec-tion and structural configurations of associated steel allow menbers to expand.
SUMMARY
This evaluation has shown that for an MSLB outside containment, all required safety functions are completed before adverse temperature effects due to increased doghouse temperatures occur. Spurious actuation of components following initial positioning has also been evaluated and it has been deter-mined that this will not occur. Thus, Duke Power has concluded that plant safety would not be adversely affected in the event of a main steam line break-in the doghouse.

CATAW8A NUCLEAR STATION - UNITS l'AND 2 ENVIRONMENTAL QUALIFICATION OF CLASS 1E ELECTRICAL EQUIPMENT LOCATED OUTSIDE CONTAINMENT EXPOSED TO PIPE RUPTURE ENVIRONMENT Note '.
The methods employed to evaluate pipebreaks and to determine the resulting environmental parameters are discussed in Section 3.6 of the Catawba FSAR.
Note 2 The pipe rupture environment is assumed to exist for 21/2 hours (except for one area of the Auxiliary Building, Elevation 543' which exists for 2 5/6 hours) based on 30 minutes at the peak temperature after which action by the operator isolated the break and allows the Auxiliary Building temperature to decrease to normal in 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. .Use of the term " Continuous'! indicates operability required /
demonstrated throughout the pipe rupture period.
The pipe rupture environmental analysis for the Doghouse was conducted seperately taking into consideration different sizes of main steam line breaks. The equipment summary sheet parameters are based on the " worse case" size break with respect to actuation time of the equipment and the time when the Doghouse temperature.
reaches the qualification temperature of the equipment. All equipment located in the Doghouse is identified under " Equipment ID".
Pressure: Not a significant qualification parameter for pipe rupture outside the containment since all locations outside containment are open areas not susceptable to pressure build-up. It should be noted that the pressure in the doghouse is a spike (8.85 psig) of less than 1 sec. duration.
Relative Humidity: For outside containment ruptures of piping systems operating at temperatures less than 200 F, area relative
-humidity is not a significant qualification parameter.
. This pipe rupture temperature precludes flashing of the liquid which could significantly increase area relative humidity. Additionally, evaporation of the liquid does not significantly increase area relative humidity due to the large open areas in which the pipe rupture occurs and tha relative short duration of the pipe rupture.
Radiation: There is no significant increase in radiation levels outside the containment as a result of a pipe rupture outside the containment.
Chemical Spray: Not a qualification parameter for pipe rupture outside the contaiment since there is no chemical spray outside the .
containment. '

, , , .y o i Rev. 5 Submergence: Based on analysis performed by Duke Power Company, it has been determined that there is no safety related electrical equipment, required to mitigate the event causing the flood (e.g., pipe rupture) or required to bring the plant to a safe shutdown condition given a flood event, located below the postulated flood levels.
}lote 3 The equipment listed is a NEMA 4 enclosure containing general application devices-(e.g., relays, switches, terminal blocks, etc.). The qualified environment is dictated by.the single limiting device contained in the enclosure. The enclosure and device qualification is documented in calculation CNC-1381.05-00-0054.
