Inis ren et covers the operation of the Yankee Atonic Electric Conpany cinn* at E.cwo, :hssa:nusetts for the nonth of July 1962.

'ne plant renained in a cold, depressurized and borated con 0ition nrc . ment u.e neriod. On July 3rd, refueling of the reaeter was conpitted with

.r.sertien cf r.inetcon new fuel assenblies in the !!orthwest quadrant cf the

n :. A r;tescopic insptetion of the lower core support plate and scarce vEnes

r tr ; ;re operctier, showed no unusual conditions.

Cperation of the fuel handling equipment during the refueling was quite sr/>ain in general with as nany as 18 fuel assemblies being unloaded or loaded

rir.; a ton hour shift.

During July an underwater examination of two spent fuel assenblies pro-Deced fcr use in cn extended burnup test in Core II was made. Thr. inspectien was

taucted in tne shield tank cavity using a borescope and binoculars for viewing.

c dinensicnal distortion af the assemblies was evident nor was any crud builoup

.eiected. With the visual inspection disclosing no defects, the two assenblies wera cui;cd to be suitable for the extended burnup test and were reloaded in the cc re .

Uith refueling conpleted,a thorough baspection of Core I control rod m rber sections was conducted underwater in the spent fuel pit. Feeling of

ne nickel plating on a nunber of absorbers was quite pronounced. The actual 1Lf tin.; cf the nickel plate was visible on certain vanes while on others the surface color and texture indicated that the plate had probably been removed prior to tne ins pe ction. The degree of removal ranged from a relatively snall ic e . cn some absorber vanes to as much as 80 percent of the area on other absor-ec: vanes.

/crtical scratches ranging from a few inches to the total absorter u " . :n lergth . cre detected on sone of the vane surfaces. "he addition cf ra .:: as on Cere II abscrber vancs should prevent such surface scratents.

Fericaic inspecticns of a Core II control rod absor'cer section nave t er in pre;rets since installation of the new absorbers in the reactor. A

.:e : reneral cf the nickel plating has been detected on one var.e of the

=croer ander surveillance.

kepresentatives of the Westinghouse Atonic Power Departnent under an n.:..C. :entract ecnducted an underwater inspection of four+cen Core I fuel a::cerlies and selected Core I control rod absorber sections during July.

2. A der.ineralized water supply line was installed during. July.

The new line originates at the low pressure surge tanX nake up pu ? discharge and terminates on the vapor container charging floor, i'he installation provides a denineralized water supply for decontardnation of the shield tank cavity and also scrves as a feed for the jaaking pump supply tank.

Hralth and Safety ..

Liquid waste with a total activity of 2.2 nillicuries was d.ischarged frer,the plant durirg July. Sixty-four drur.s of solid wasto containirg 155 r.il11 curies ver shipped for off-site disposal whils 67 barrele of solid easte containini; 258 nillicuries were drurned during the same period. At all tines the concentration of waste products discharged or shipped from the site van well below the naxinun peredssible.

No gaseous waste was dise' .ged from the plant durint, July. . ;

Radiation levels in

During this semi annual period. Ti.D data was invalidatcJ at all stations during \ugust, October, anJ Deecmber due to e problem with contaminated film badge holders used concurrent with 1LDs at environmental radiation monitoring stattons. ihis use of film badges and TLDs at each station was intended to serve as a cheek on the use of flim badges to monitor low monthly exposures. !!owever, significant corrosion product contamination of one film baJge holder and minor contamination of several others uscJ during the thos e mentioned months resulted in much elevated readings for the ILD with which it was paired for the month as well as inercases in other station's llDs k i rt n prox tmity to the film badge holder for a period of time before read-out. Ihr recorded exposures showed a very large range on the tour readout at a of vaeh ILD pad (CaSO4:Dyj indieting that the TLDs were in close prosimity to a physically small source.

le prevent a recurrence of such a problem, a number of procedures have been wJopted, Iirst, all film badge and 'lLD holders will be labeled with an identitying number and will be used only at the correspondirgly number (d sang le location. Second, all film badge holders and TLD holders will be ches6eI tor contamination prior to use. In the near future, all ~lLD read-out will be hanJ ted by a nearby offsite service, thus avoiding occasional piolIsns with low-lesel ensironmental ll,D readout in-plant.
