De tr Mr. Denton:

Raltinore Gas and Electric Ccrrany hareby requests an a~endment to Crariting Licenres DPF-53 and DPP-69 for Calvert Cliffs Units 1 and 2,

• ecr ectively , wit' the sui nittal of the follevine propored chant es to the

(FC? 70-12) Parn;manh h .7.8.1.a : Chanr,e the tootnote on rare 3/h 7-?6 as skovn on the attached cheets to allow a defer ral of the next required virual inspoetion for the inaccessible hydraulic anubber Froup until the cor .encement of the autumn refueling outare , currently scheduled to start October lh, 197o. This deferral vill delay the !nspection by antroximately five weeks as this r.nubl er rroup is current' y on the six nonth inspection interval with the insrect'on re ,uired to be performed not later than "cptember 10, 1979 Din-unnion U-2 inaccessible snubbers are current 1v on the six nonth + 25's iu ~nec ti on laterval . The next inspection is currently required by Septenter 10, 1079

?;or.nlly, to minimize personnel radiation exposure and because the + emnerature inside of the pressurizer enclosure in so high during operation, the snubber inspection rush he nerfor.ed with the unit in cold shutdown. The next scheduled cold shutdown for U-2 is the refueling outace

. pace 2 currently scheduled to commence abou- October 1079. Therefore, to accomplish this intnection as requir u, an .:nnlanned shutdown entirated to be 2h-36 hours in duration vould be neces sary. This does not incl:de the tine required to cool down and heat up. A tennorary relief from paragraph h .7.8.1.a to allow the visual inspection of these snubbers to be perfcrmed during the urconing outage would be justified based on renlacement energy conts and personnel exposure as discursed in the follnving corparison of al te rnatives : Al ternative (1) Conply with the Technical Crecification and shutdown at the six nonth interval and inspect all inaccessible snulbers, Al ternntive (?) Perform the inrnection o# all inaccessible nnubbers with the plant operating, Alternative (3) n elax Technical Cree-ification h.7.8.1.a as described alove. An anal:. sis of each alternative is as follows:

(1) This course of acticn fully conplies with the T echnical Speci fication.

However, a prerently unscheduled cutage vould be reluired before "eptember 10, lo70 che total cost in terns of replacement energy would be apprcximately 8500,000. Thir assunes the outa.;e lasts the tinimun entir- ted duration, 2h hours. n more realistic estimate is 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> (and, ence arain, thid does not include cooldown/heatup time).

This would result in a 505 increase in replacement enerry costs.

Conplir.nce with the requirenents of the Techaical Precifications in this manner, since it vould only result in approxtnataly a five-week-sooner insp"ction date, would not arpreciably enhance the overall safety of the plant. In lition , all snubbers were "<mnd to have baen operable durine the nost e ent inrpaction, conn' s ed in January 1970 (2) This course of action would also connly with the Technical Cpecifications, however, the inaccessible snubbers rouid be inspected during pInnt operation. The cost in terns of r<tdiation exposure vould be prohib-

~

itiva. To perform an irspection of all 176 cnubbers ufuld require nnproximately h0 manhours and result in excess of 300 manRem.

(3) This cource of action, which is proposed, would provide continued adequate assurance of the nublic health and safety with no unnecessary increase in rover traduction costs or rersonnel radiation exposure.

(FCR 79-28): Pararraph h.6.2.1.c: Chanre the insrection intervnl for the sprg, systen nozzles from five years to ten years a" shown on the attached chs .

Diccussion A nozzle flow test on the containment spary ring is required every five (5) years by technical specifications.Section XI of the current edition of the ASMF Boiler and Pressure Vessel Code which is applicable for Calvert Cliffs, (197h edition through Cunner 1975 nddenda) exennis the open-ended portions of non-closed systems frcn any krdroctatic t arting and does not substitute any other testir g requirunent for there syntens (para, lWC-5?20).

Section XI of the 1977 edition throuch "urner 1378 aidenda of the ATE B & PV code has been reviewed and found neceptable by the NRC.

The connent period required by law before incorporation of this edition has expired. No cornents were received by the NRC, therefore, this document vill be made Inv vithin two months.Section XI of this ciition of the code states that a nornle flow test be performed once per inspection period (10 ycsrs) (para lWC-52P2).

Therefore, this technical crecification chance would chance the interval in which we perform the norny rine nor le flow test to fall in 1ine with the curront views of the '?C ard A?"E code cenrittee. "his change vould elininnte the nerfernnnec of four (h ) of thene tente rer unit over the lifetime of the plant cavinc ceveral thounaads of dollars and hundreds of nan-heurs required for its perfornance.

Chnnre No.

(FCR 79 h6): Incorporate the propoced 10 CFR 50 Aprendix I Technical Opecifications into the Operation Licencer. Thece technical stocificationc vere previously submitted in a letta dated March 15, 1979 and are hereby included by reference to that nui ritial (see refere2 red letter).

(FCR 79 h9): ~hange parag-aphs 6.P and 6.5 as shown on the attaehed pares to reflect the institution of the new Production l'aintenance Dep trtment ( Ff fec tive .Taly 1,1979) . This change involves both orranization chart changes and Off-Site Safety and Feview Cormittee (CSCPC) nembership ch an ge s .

Discunsion The Production "aintenance Denartment is a new Pepartment within the Curply Division which has taken over noot of the plant maintenance functions for Calvert Cliffs. As a result, there have been necessary chamens in the Corrany and Plant arraninntion charts to reflect the modified a h inistrative chtnnels. In addition, since some of the expertise which van previously contained within the F] ectric Production Departrent, and which conrtituted part of the CSSBC, is now in the Production Maintenance Depart.ent, it is nomsnarv to reflect these chances in the appropriate sactions of the Technical "necifications of both Units. These changes are considered to be strictly akinis tr,tive in nature and have no impact on over'31 plant safety or 'he heal th and safety of the mhlic.

Pn1tircre Gas and Flectric Correny beran conductinr, aquatic ecological studies ir the region of the Chesapenke Bay near tre Cnicert Clif fs iaclear Fover Plant site as ca"'.y ns 1968. "hese studies were desicned to yelid baseline dath by which the effects of the operation of the plant could be judged and to provide infermation to ruide future

tulies in this araa. k' hen Calvert Cliffs Unit I received its operating license in 197h, many of these studies were incorporated into the Fnviron-rental Technical Cpecifications ( r~'S ) . Tne nurpose of those studies v ts +o investicate and determine the effects , if any, of the plant circulating vater discharge on certain water quality m rameters as well as the planktonic, nektonic and benthic corr.unitics in the vicinity of the plant. Additicnal studies concerning the effects of plant operation on aquatic organisms g.xd throuch the condenser cooline vnter sysb i were also required by the ETS. W n Unit 2 received its operatinr, licence. in 1976, a similar set of specifications was vrltten and eventrally the two ETS vere combined in 1977.

Since unit 1 heran operating, the Company has been submitting periodic reports analyzing the results of these studies. The latest rep >rt (Reference 1) van desirned to analyze all of the data -ollected since Unit 1 beran operating and, as such, assesses the effects t approximately two years of operation of Unit 1 (1975, 1976) and two yeare of operation of y r/ ,h ,ne n

Tnce 5 both Units (1977, 1973). Analynis of data collected dur*7c the nquatic chemistry, prinary productivity and phyteninnkton twonony studien did not reveal any cirnificant plant-induced impacts. Some 1.nraneter variations, n1though not of sufficient narnitude to be statistically sienificant, were noted within the dincharge plume itrolf.  ;:owever, even thece observations were not no t nbl e a f' er the pire tocre dilutei with receivine vnters.

Basis More than ene year of entrainment data for Calvert C1'ffs Unit I has been cou ec' d at this time. Since there is no reason to expect differ nt effects of ertrain-ment on aquatic organisms pu= ped through Unit 2 rather tha . thrcuch ynit 1a modified version of the Unit 1 entrain. ment study vill be cond ted. These studica wi11 he conducted during the warm summer months when the 1.irgest et et on entrained cr6ani:ms is expected. Ichthycplaakten studies during the first year of operation of Unit I have shown very lov densities cf eggs aad Irvac in the vicinity of Calvert Cliffs. For this reason, ichthyoplankton entrair ent st udi es will not be conducted far the Calvert Cliffs site. l 3.1-10 JUL 2 9 577 kb!- 7. n' ?
