EIGHTH SET OF INTERROGATORIES y In response to the interrogatories propounded by John F. Doherty, Houston Lighting & Power Company

( Applicant) answers as follows:

INTERROGATORY NO. 8-2:

Will Applicant's control room be equipped with a data recorder such as the one described in the Kemeny Commission report in its findings on pg. 30 as finding #9, and called a reactimeter?

(a) Has applicant considered such a device as part of its control room?

(b) What objections would there be to a permanently installed reactimeter?

RESPONSE : (a) No (b) The ACNGS control room design includes the use of recorders which not only record important para-meters for post accident analysis but give the operator useful real-time information as well.

Additional duplication of this recording capa-bility with a reactimeter device is unnecessary.

1701 327 8 *108o 0 1

INTERROGATORY NO. 8-3:

Cite the three most recent documents which show that irradiation increases cladding strength as stated on pg. 4.2-14a, and make these documents available to this Intervenor, please.

(That is, documents in your possession) .

RESPONSE: This data is discussed in Licensing Topical Report NEDE 24011, "GE BWR Generic Reload Fuel Applications" dated July, 1979.

INTERROGATORY NO. 8-4:

Cite the three most recent documents in your possession which show the design fission gas release model employed in the determination of fuel rod plenum size and clad wall thickness has been shown to over predict available data on fission gas release when applied with a pellet-clad thermal conductance value of 1,000 btu /hr-f t2 and make these documents available to this Intervenor. (Note: see pg. 4.2-14b of PSAR on this item).

RESPONSE: NEDE 20944 - BWR 4, 5 Fuel Design, October, 1976 (Applicant only has Amendment 1)

NEDE 20948-lP - BWR 6 Fuel Design, December, 1975*

(Proprietary document)

NEDO 10505 - Experience with BWR Fuel Through 1971, May, 1972.

INTERROGATORY NO. 8-5:

When does Applicant expect to have fuel rods operating at linear heat generation rate of approximately 21 kw/ft, other than abnormal occurences? (Sec 4.2-14b PSAR) .

RESPONSE: Applicant does not expect to operate with a linear heat generation rate of 21 kw/ft.

INTERROGATORY NO. 8-6:

Has applicant any data other than NEDO 10329 for giving the distributien of fuel rod internal pressures used in LOCA rod perforction calculations during LOCA? (See PSAR 4. 2-14 f) .

• / This docunent is now available for inspection under previously agreed uptn procedures for proprietary documents, Note that this rer,ponse changes the response given to Doherty's seventh requesj. for documents, item number 14.

1701 328

RESPONSE : Yes, a discussion on fuel rod internal pressure during a LOCA can be found in NEDO 20566 "GE Analytical Model for LOCA in Accordance with 10 CFR Appendix K,"

January, 1976.

INTERROGATORY NO. 8-7:

What is accomplished having the LPCS initiated by drywell high pressure of reactor vessel low water signal for a LOCA? (See PSAR 6. 3-21)

RESPONSE: Reactor vessel low water level and drywell high pressure signals indicate that there is a possible break in the Reactor Coolant Pressure Boundary (a LOCA) ; hence, the LPCS is initiated to provide cooling water. (There is no page 6.3-21 in the ACNGS PSAR.)

INTERROGATORY NO. 8-8:

2 What is moment of inertia in lbs/ft of applicant's recirculation pumps?

RESPONSE: 800 lb/ft2 1701.329 INTERROGATORY NO. 8-10:

Is one of Applicant's suppliers of componenes or supplies the Target-Rock Corporation or a corporation, company, etc., that uses " Target Rock" as a tradename, symbol or mark?

(a) If so, indicate what this supplier makes, and where these devides components or supplies will be used in ACNGS, please.

(a) N/A INTERROGATORY NO. 8-11:

Are any check valves to be supplied by Velan Engineer-ing Corp.?

RESPONSE : Velan Engineering valves have not been purchased or specified to date.

INTERROGATORY NO. 8-12:

RESPONSE : No INTERROGATORY NO. 8-13:

Is there any piping section in the reactor coolant system where the length of the pipe is 50 times larger than the pipe radius and the pipe is of stainless steel?

RESPONSE : No INTERROGATORY NO. 8-14:

(b) Same wording as 8-14, but 50 times greater?

RESPONSE : Yes 1701 330

s -

(a) Yes (b) Yes INTERROGATORY NO. 8-15:

In the analysis of axial (longitudinal) of the ACNGS steel containment standing shell, is the stress presumed to not vary greatly over a distance equal to about half a buckle wave length? If so, why?

RESPONSE: Yes, the stress is presumed to not vary greatly over a distance equal to half a buckle wave length. For the ACNGS buckling evaluation the caximum stress in a panel (portions of the steel containment shell usually between stif feners) is assumed uniform over the area. This assumption is more conservative than using a varying stress distribution.

INTERROGATORY NO. 8-16:

How has applicant determined loads on its steel con-tainment shell?

(a) Has it used any of the following codes: NASTRAN, Marc, SAP 6, or ANSYS?

(b) If it uses any other code, please name it here.

(c) Regardless cf code use, please indicate'if a

" linear" bifurcation analysis has been used or is planned it. the future.

RESPONSE: The loads on the containment are discussed in Containment Structures Design Report , Rev. 2, provided to Intervenor previously.

(a) ANSYS is used to determine the overall steel containment responses to dynamic loadings.

NASTRAN is used to compute the behavior of elastic structures under a wide range of loading conditions.

(b) The programs used for the detailed analysis of the containment shell arc labeled E1374, E1779, E1775, E781, and E775. They are Chicago Bridge and Iron programs.

s -

(c) A linear bifurcation analysis has not been performed for ACNGS Steel containment nor is one planned.

INTERROGATORY NO. 8-17:

On page 5.5-4 of the PSAR, it states that the pump impeller is designed for as long a " life" as is practical.

Applicant has stated in a previous interrogatory, "there is no regular inspection planned for the recirculation pump im-pellers", (pg. 2 of Applicant's answer to J. D. Interog. 7-2) .

Does Applicant have any data on the longevity of pump impellers in these pumps with the particular requirements planned for them?

(a) If so, please identify and make available such information?

(b) How frequently will the recirculation pumps be inspected?

RESPONSE : (a) The type of recirculation pump to be utilized at ACNGS has been in use for approximately 10 years and no impeller replacement has been needed.

(b) There is no required or planned inspection of the pump impellers. Pump casings are subjected to In-service Inspection every 10 years.

All documents requested which are in Applicant's possession will be made available at the Engineering Development Complex. No expert witnesses have been identified to date.
