' Dockets 50,65 and 70-687.,: Order Modifying LicenseL

REFERENCE:

(a) Cintichem Letter (JJM/113.90B): dated May 31,.1990:

(b) Cintichem' Letter (JJM/129. 908) . dated June 21,.1990:

Cintichem has completed the repairsL to . the O Canal and Gamma Pit sections . of the' reactor - primary water ' systems described in the ..above referenced ~ correspondence. . The system has been1 filled with water-and

~

leak tested.  ;

The, referenced letters indicate , a : normal . operating. water level of.- 12 feet.iin the Canal and Gamma' Pit : sections.L . Cintichem has. decided'to operate at a level of 10' feet of water and has performed leak tests at ,

this level which meet the leak test criteria set down in, Repairof i Canal' and -Gamma Pit Specifications 90-03,- (see Ref. a) .'

The current technical specifications on.. water :levelL are based' on maintaining a minimum hydraulic head above, the. operating coreJand keeping containment of the reactor building while -- the reactor. is-operating. The reactor has~ been defueled: and there 'is no intent to '1 resume operation. The only purposei for : maintaining . water- levels during decommissioning will be to provide = shielding during transfers  ;

of radioactive materials for. disposal. . Ther10: foot: water level-above j the canal floor will provide 8' feet of'waterEover-theJtallest shipping; j container that will be- loaded in' the : -. Gamma ' Pit. . -Radiation l measurements will be conducted- on- all. typical components to be j transferred.

If these measurements indicate abnormal - radiation fields, we will modify our- procedures and tooling. to reduce radiation exposure to ,

personnel to levels ALARA. for this type of l operation. . In addition,.

all' existing area radiation monitors willL be operational and : :all-transfers will be' closely monitored; by Health Physics personnel-:and j controlled by-radiation workipermits. >
