4) All release types as listed in 1 and 2 above, at the vent stack and as listed in 3 above, at the Standby Gas Treatment System whenever there is a flow, are continuously sampled by charcoal, particulate and composite samples which are analyzed for iodines, principal gamma emitters, gross alpha, Sr-89 and Sr-90. Noble gases, gross beta and gamma are continuously monitored by noble gas monitors for the vent stack and the standby gas treatment system.
b. Liquid Effluents
1) Batch waste release tanks are sampled each batch for principal -

gamma emitters, I-131, dissolved and entrained noble gases, H-3, gross alpha, Sr-69, Sr-90 and Fe-55. ,

2) Continuous releases are sampled continuously in proportion to the rate of flow of the effluent stream and by grab sample.

Samples are analyzed for principal gamma emitters, I-131, dissolved and entrained noble gases, H-3, gross ipha, Sr-89, Sr-90 and Fe-55.

' FAILURE TO PERFORM THE MONTHLY SOURCE CHECK OF THE OFFGAS PRETREATED LOG AND LINEAR fliOCESS RADTXTION MONITOR ON TIME DESCRIPTION AND CAUSE OF EVENT:

A monthly source check of the OFFGAS (0/G) pretreat log and linear process radiation monitor (PRM) was performed late. This source check is required to be performed once every 31 days. This surveillance is performed by the Radiation Protection Department (RPD), using the General Surveillance Tracking Program (GSRV) printout as a schedule.

In the latter part of August 1994, the GSRV printout format for the RPD was changed. The change that occurred was the GSRV printout to the RPD would be a single printout and would include all of the Health Physics (HP) surveillances, and the HP Department surveillances.

Prior to this change there were two printouts, an HP printout and an HPD printout. The HPD printout contained all the RPD surveillances. This printout was approximately five pages in length and would include the surveillances for '

the O/G protreat log and linear RPMs. These surveillance are unit specific, that is listed by each unit specifically, Unit 1, Unit 2 or Unit 0. Unit 0 is used to indicate the surveillance applies for both Unit 1 and Unit 2.

The HP printout contained all the surveillances due on the RPD instruments. This printout for a six week period is approximately 50 pages in length. These items would be associated with Unit 0 since they are performed for both Unit 1 and Unit

2. When both GSRV and Electronic Work Control System (EWCS) reports were combined, the resulting printout was approximately 55 paces in length. The first 50 pages being Unit 0 surveillances, and the last five pages being specific to Unit 1 and Unit 2 surveillances.

All GSRV/EWCS surveillance printouts are unit specific and in date due order.

All the items are printed first in date due order specific to Unit 0, then items for Unit 1 are printed in date due order, and tinally items for Unit 2 are printed in date due order. The RP Department GSRV Coordinator only went through the first 40 pages of the GSRV to sign off the required items. He was unaware that the GSRV/EWCS paperwork had been changed and the last five pages of the teport were specific surveillances for Unit 1 and 2.

- On September 20, 1994 it was discovered that the monthly source check of the O/G pretreat log and linear PRMs had not been performed. The monthly source check was immediately scheduled, and on September 26, 1994 both units passed satisfactorily. The missed surveillance for the monthly source check should have been performed within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> once it was discovered that it had been missed.

e 9 a CORRECTIVE ACTIONS:

l' . The monthly source check was immediately scheduled, and on September 26, 1994 both units passed satisfactorily. (This item is complete) .

2. Revise the current ODCM to provide specific guidance concerning any missed surveillances. Action Item Record ( AIR) 373-200-94-0215401 has been generated and will track completion of the ODCM revision. The AIR due date is July 15, 1995, this item will be completed then.
3. Include this event and investigation in the next Semiannual Effluent Report. Action Item Record (AIR) 373-200-94-0215402 has been generated and will track completion of this commitment. Submission of this report will complete this item.
4. A memo was generated November 11, 1994 to communicate this event and the revised GSRV/EWCS format to the personnel in each department responsible for GSRV surveillance tracking. (This item complete).
