Accoruisig ' to thd Advisory ' Cow.ittee on Reactor Safe-guards (Ref.fl)'the nidland Plant is tbc first dual parpore reactor plant to be licensed for construction. That'is, part of the 'stcam produced by the steam generators seithin the reactor plant will be exported to Dow Chemical Company for uso in canufacturing chemical products. The romainder of the nteam will Le used to generate electricity at the reacter-plant. Isecause the reacter coolant will be radioactive, questions are naturally raised as to the possibility of il) radioactive contamination of the Dow products and (2) radioactivity released to the environment, since 25% to 40%

of the process steam will not be recovered. To provent' radioactive contamination of the process steam, it is necessary to isolate the procccs steam from the reactor coolant by at least one or a scricc of heat exchangers which must not develop.

primary to seccndary'1caks;_i.e. the integrity of the physical barriers between the primary coolant and process steam must lac maintained. 'Ihic paper cites evidence of heat exchanger malfunct. ion which should bc useful in estinating what might ba expected in the way of radioactivity Icakage to the process

steam (Items #1, 2, and 3 which are attached). Of course, the extent of fuel element cladding -failure in the reactor will affect greatly any estimates of radioactivity leakage.

However,-this paper does not consider the question of fuel element performance capability for the Midla nd reactors, except.

as to recormend that an independent review be conducted ~as to the adequacy of the fuel. element design for the planned power ~

4 operations.

h shippiagywrt h essurized wtur nese' ur plant operated wita come 1 (230 Ina) for alcat six yars using Cerar stcen <re:. craters--two generators ( l A and 1 D) were of the rtruight tube ucciga (restar tihocler Corp.) snd the othar tur, ( l b an.d 1 C) ucre of the U-tube design (Sabcock and Wilcox Co.), (nce P.eI. 2) the tubing vas made of stainless sixel.

Iten il briefly summarizes the ex;crience vitit the Core 1 steam gener.: tors. It reports that Icakage and videspread n:.d entonsive crcching occurred in one of the L bccek and t?ilcax scncrators. Presumably, Bettic At mic Tover Laboratcry (Shippingport designers) had subni'.ted repcrts to the AEC concerning the performance of the Corc 1 steam,qenerators and the radiolecical conecquences of the leaks. It is recon cnded tlat these reports Lc obtained. !!cwever, since Corc 1 opcrated with no fuc2 f ailu t er. (except for 3 tiny pin halc leaks in ti.e cicdding of tbo natural uranium feel rods shich vore barely detectabic), the extent of radioactivity Icakage into the secondary system was minimized. (Ref. 3).

Shippingport Core 2 (505 P.6u dc=1gn pcwcr, but norr. ally operated at 67% of full power) began operatien in 1965. 1;ew steam generators were inctalled for Ccre 2 with groater hect transfer capccity to hcncle the increase in core power. Tr.e tubing wss nede of Ni-Cy -Fe alley (InconcM "to enhance the integrity of the syntec." (Ref. 4). (In Item 72, Cycrley states that Iconal has been selected as a stcndard for present day steam generators over stainicss steci for better corresion resistance. Lycriey also states that primary to eccendary Icaks occurred with tne Rowc-Yankee steam generators.)

As with Corc 1 the JA and ID units for Core 2 are straight tube, roster Wheeler generators and the 1B and 1C units are U-tube Babcock and Wilcox goncrators.

Despite the :.uitch to Ni-C r -Pn alloy for tubing n.aterial,

- the Coro .2 steam generators have experj enced leaks:. Item ;3 in a. chronologienl. cruupliation of excerpts f rom the Shipping-part Quarter ly I'ro<f . n:3 Reports dealing with the:.e leaks and a

related tritiu.a ' activity leveln in the primary coolant. The execrptn begia with WAPD-MRP-ll3 and end with WAPD-MRP-135 cnd cover the period from Juno 1966 to January 1971. The reports wcre issued by the Bettis Atomic Power Laboratory.

The highlight 0 from these execrpts'are.as follovs:

1. Both of the Babcocke and Wilcox' U-tube generators (13 and IC) developed loaks and one of the Foster-Wheelcr, ctraight tubo generators (lD) developed leaks. The Icak rates wero ac.follows:

1D: .21 gal /hr--25 gal /hr (129 nal/ min--1570 ml/ min) before the leak rato increased to 100 gpm.

1C: 8-9 gal /hr 1D: 3.6 gal /hr After the lu generator was returned to service (after the leaking tubos were plugged) it again experienced a rapid leak of 150 gal / min and was then removed'again from service for extensive investigation.

2. Tho'cause of the leaks were not identified.

3. bottis Laboratory cubmitted a comprchensivo report'to the A1:C regarding the effect of steam generator primary to secondary leakage on reactor plant operation. (.Sco WAPD-MRP-135, p. 1) Bettis described this-roport as-

'follows:

The Dottis Laboratory submitted to,the-AEC for-information during tnis report period an ovalu-ation of.the effect that various-steam generator leak ratos would have on continued plant opera-tions. The effect of continued operation with a leaking steam generator was evaluated with respect to radioactive waste-disposal system processing capabilitics, contamination of the secondary plant, and eventual discharge of activity to the~

onvironment from both normal and postulated accident conditions. This evaluation providos

_4 s

"g- ,

t ,

guidance a:: to when a steam generator with primary to secondary leakago should be removed from service for maintenanco.

4. The tritium Icvol in the reactor primary coolant reach a high of 55 micro-curies por liter (pc/1) and then decreated due to coolant leakage. The production rate of tritium was estimated at 2.4x103 pc/hr.

Based on thosc nighlights the following comments are offered:

a. Although, not reported in the WAPD-MRP CAcerpts, one of the rapid leakages in the IB generator almost result'od in the initiation of the Core Safety Injection System, which is otherwise known as the Emergency Core Cooling System. (Ref. 3) The loss of primary coolant caused a drop in primary pressure from 2000 psig to near 1300 psig, which is the trip point for Safety Injection.

The question arises as to what would happen if the emergency cooling system were initiated by a rapid leak in the steam generator tubing. Would the result be a flushing of the primary coolant radioactivity into the secondary system? Are primary coolant isolation valves provided for each steam generator?

b.

A tritium lovel of 55 pc/l implies that approximately 4.7 cdrics of tritium total, were present in the Shippingport primary coolant:

3000 ft3 of coolant x (2.54 cm/in)3 x (12)3 in 3

/f t3 x 103 1/cm3 x 55 pc/l=4.7 curies /H 3 However, Core 2 operation has been marked by no detected fuel failures (see WAPD-MRP reports in gonoral) and so it must be added that the radioactivity levels in the primary coolant system might, therefore, be concidered minimum.

.c. - The.- report r.cationed in M PD-MMP-135', p. 1 would opjwar to bc highly, relevant to the concern for. radioactivity icakin ; into the Co.i process stoan. It in therefere-recop;cended that the Atomic Safety and Licensing Board obtain the report for review by all interested parties, includine; the Mapluton Intervencra. Mrs. Mayfio1d of.

the ALC's Division of Technical Information Extension at Oak Riilge (phune : 615-433-8611, ext. 34765) . is.

attempting to . locate the report within the A1:c.

Cics Rock Point Feedwater Heaters Thd' Big Rock Point Nuclear Power Plant (3 oiling.Uater P.ecctor).had experienced considerable difficulty with feed .

water heaters. One or coro heat exchangers had to be renoved from service because of a general rotting away of the tubes.

These tubes were not nade. of either stainless steel or Inconel.

It was plannbd to replace thcce heaters with new heat exchangers c ;uit ped wi th stainlens stecl tubing. (Ref. 5) It would bc of

. interest to know-whether thiso new heat _exchangers were placed.

in service and whether any 1 aks had developed within them.
