y 4 TECHNICAL REQUIREMENT p

. DEPRESSURIZATION OF SUPERNATANT TREATMENT SYSTEM POR-MAINTENANCE l

l APPLICABILITY This requirement is applicable for all maint2 nance work to be done on STS.

OILTECTIVE The objective of this requirement is to prevent backup of high-level waste (HLW) into the STS operations area by removing the driving head necessary to cause back flow during all occasions that inadvertent depressurization of instrument air systems could" occur.

REQUIREMENTS 1.

PROCEDURES'FOR SHUTDOWN OF STS SHALL REQUIRE DEPRESSURIZATION OF TANKS D-001,

. SUPERNATANT MAKEUP-FEED TANK), AND D 004 (SLUICE WATER LIFT TANK)

(

IMMED_IATELY UPGN SECURING THE ASSOCIATED PUMPS (G-002 AND G-003).

2.

ACCESS TO THE LEVEL / DENSITY INDICATOR CABINETS SHALL BE UNDER THE CONTROL OF THE SHIFT SUPERVISOR.

3.

NO MAINTENANCE SHALL BE STARTED ON D-001 OR D-004 BUBBLERS OR VESSEL PRESSURIZATION SYSTEMS AND THE ASSOCIATED PIPING, TUBING, INSTRUMENTATION AIR SUPPLY, ELECTRICAL POWER SUPPLY, OR ANY UORK TO BE DONE IN THE LEVEL / DENSITY CABINET, UNTIL D-001 AND D 004 ARE DEPRESSURIZED.

DURING WATER RECIRCULATION ANY MAINTENANCE ITEMS, NOT INCLUDED IN REQUIREMENT j

  1. 3 CAN BE PERFORMED WHILE D-001 AND/OR D-004 ARE PRESSURIZED WITH THE AUTHORIZATION OF THE SHIFT SUPERVISOR AND THE PROCESS CONTROL ENGINEER ON THE WORK CONTROL DOCUMENT, E.G., WORK ORDER OR OPDR.

5.

IN SITUATIONS WHERE MAINTENANCE ON OPERATING SYSTEMS IS REQUIRED WHILE THE SYSTEM IS PRESSURIZED AND PROCESSING SUPERNATANT, MAINTENANCE CAN BE PERFORMED WITH THE EXCLUSION OF THE ITEMS IN REQUIREMENT #3, WITH THE EXPLICIT APPROVAL OF THE OPERATIONS MANAGER AND THE RADIATION AND SAFETY MANAGER OR THEIR DESIGNATE ON THE WORK CONTROL DOCUMENT, E.G.,

WORK ORDER OR OPDR.

l 6.

ANY MAINTENANCE ON OFFICE OR BUILDING SYSTEMS DURING GUPERNATANI PROCESSING REQUIRES 00,Y THE AUTHORIZATION OF THE SHIFT SUPERVISOR AND PROCESS CONTROL ENGINEER TO ASSURE THERE IS NO IMPACT IN SAFE OPERATION OF THE PROCESSING i

2.

VERIFY THAT BYPASS VENT VALVES 50-HV-719 OR 50-HV-718 ARE OPEN TO DEPRESSURIZE TANKS, RECORD IN SHIFT SUPERVISORS LDG BOOK.

3.

4 CHECK AUTOMATIC SHUT-OFF VALVES THAT PREVENT BACKUP OF HLW INTO OPERATING AISLE ON A SEMIANNUAL BASIS.

TR-IRTS-4 Rsv. 3

> BASIS r~N

\\_

Due to the driving force available from the pressurized tanks D-001 and D-004 the bubbler and vessel pressurization systems on these tanks shall not have maintenance done unless the vessels are depressurized.

This requirement is needed because the equipment associated with the bubbler and vessel pressurization systems is located in the STS operating aisle. Without depressurization of the vessels prior to maintenance work there is potential to have HLW backup into the operating aisle.

Maintenance on all equipment within the level / density cabinet shall also require depressurization of tanks D-001 and D-004.

This is due to the possibility, in the confined space of the cabinet, of inadvertently causing loss of the bubbler system (s).

The access to this cabinet shall be under the control of the Shift Supervisor per Requirement #2.

During water recirculation of the STS ion exchange columns it is technically i

g-~S important to. maintain flow,,to prevent spiking of column effluents when flow is s.l resumed. Maintenance can be performed during water recirculation, with the exception of the above mentioned items, with th e approval of the Shif t Supervisor and the Process Control Engineer on the Work Control Document, e.g., Work Order l

~

or OPDR.

In situations where maintenance is required while the system is pressurized and processing supernatant maintenance can be performed, with the exclusion of items in Requirement #3, with the explicit approval of the Operations Kanager and the Radiation and Safety Manager or their designate on the Work Control Document, e.g., Work Order or OPDR.
