Instrumentation Inside of Shielded Cubicles (75-8/6)
This item was originally discussed in IE Report No. 50-302/76-
!
a.
l 8, Details III, paragraph 5, and dealt with the installation of instruments inside of shielded cubicles next to potential
'
high radiation sources. The licensee has conducted a review of both the location of instruments and valves in potential
<
l high radiation areas to determine those changes which must be made based on anticipated radiation levels, and estimated man-i hours for operation, surveillance and calibration of equipment.
b.
A licensee representative provided the inspector with a copy of the summary of the reviews which were made, specific actions taken on instrument and equipment relocation and modification, and the program for future evaluation of trends in increasing radiation levels. As a result of the review, some instru-mentation was relocated and shielding was specified for the i

make-up system letdown line and block orifice. Engineering l
Change Motices (ECN's) have not been issued for the shielding.
!
During a plant' tour the inspector noted the relocation of
instrumentation to locations outside of potentially high radiation areas but also noted that some instruments were still in these areas. A licensee representative informed the inspector that these instruments were fixed due to the sensing lines but could be relocated at a later date with the install-
'
ation of new seasing lines and could be removed to lower radiation fields for the performance of routine calibrations j
and maintenance.
'
'
c.
The inspector discussed the program for evaluation of trends
-
in radiation levels and evaluation of personnel exposures with
-
a licensee representative. Such reviews are part of the plant i
'
routine surveys and evaluation of exposures under that LARA program.

'
d.
The inspector informed licensee management that this item was closed but that the program for evaluation of trends would be reviewed periodically.
3.
Evaluation of Sampling Media Collection Efficienefes (75-19/6)
I a.
This item was originally discussed in IE Report No. 50-302/76-19, Details III, paragraph 4 and dealt with the need to estab-lish the collection efficiencies for sample collection media, especially charcoal cartridges., A licensee representative I
informed the inspector that data are being collected and evaluated but that no values have been established nor have any values been incorporated into procedures. Consequently,-
,
I this item remains open.
l b.
In reviewing the preliminary data which the licensee had accumulated for the purpose of establishing the collection efficiencies, the inspector noted that the residence time for flow through the charcoal cartridges is about 0.02 seconds.
The inspector stated that this time is too low and that the minimum residence time should be at least 0.1 seconds to provide a reasonable collection efficiency. 'A licensee represen-tative stated that the efficiency at the low residence time is low and affects the minimum detectable levels and counting statistics. Consequently, the licensee is studying ways to increase the residence time and thus improve the efficiency tut no decision has-been reached. The licensee is studying this problem as part of the overall evaluation of collection I
efficiency.

Gaseous Wasta System Modifications a.
Two ECN's were issued to change the operator on the gaseous weste discharge isolation valve (valve WDV-439) to permit throttling of the flow. The new operator permits the valve to be positioned at variable settings rather than the open-close settings with the original operator. A licensee representative informed the inspector that the new operator had been installed; a review of the Quality Assurance records indicated that the i
i two ECN's had been completed. The inspector also inspected the weste systems control panel and observed that the new controls for WDV-439 were installed.
'
b.
A licenses representative informed the inspector that an additional modification is required for the gaseous waste system to install a pressure reducing valve upstream of the waste gas decay tank monitor (RM-All) to ' prevent overpressuri-zation of the monitor. This is rcquired as th. waste gas
,
decay tanks can be pressurized to 80 psig and the design
'
pressure of the monitor housing is 15 psig. The licenses representative stated that an ECN will be issued but has not been accomplished. Testing of the discharge portion of the
,
gaseous waste system is delayed pending the installation of this valve. The inspector stated that he would review the installation of the valve at a later date.
'
5.
Facility Status During tours of the plant and discussions with licensee represen-tatives, the inspector noted the following on the Facility Status which affects completion of.the plant.
The fume hoods in the radiochemistry laboratory are not operable, a.
delaying the check-out of radiochemistry procedures. During preliminary tests, the air velocity at the hood face was determined to be approximately one-half of the acceptable
!
velocity (approximately 50 feet per minute vice 100). A licensee representative stated that this condition would be corrected when the hoods are balanced during final ventilation system testing and balancing.
b.
The proposed Environmental Technical Specifications require that releases from the liquid radioactive vasta system be made on a batch basis after mixing and representative sampling.

The laundry sump can be circulated,. sampled and discharged through the liquid discharge line but cannot be i.mlated from the system inlets during circulation and discharge so that the discharges are not on a batch basis nor are samples necessarily
'
reptasentative. A licensee representative stated that this situation was under study and that a system modification was under consideration to permit batch releases from the laundry
'
sump.
The solid waste compactor (balar) is installed on its founda-c.
tion. The platen exhaust passes through a filter and discharges into the room just above the baler. No enclosure is provided around the platen or the unit. No markings were visible on the filter to indicate if the filter is high-efficiency or just a roughing filter. The inspector pointed out that the present installation was not adequate to prevent the spread of contamination or creation of airborne radioactivity problems
'
during the packaging of waste. A licensee representative acknowJ~M these comments and stated that modifications were being which would correct these conditions and that the s
.cion would be corrected.
.
d.
The area designated as the equipnent decontamination room is being used as a trade work shop. No equipment for the decon-tamination facility has been installed. Licensee management acknowledged that this facility is incomplete and that it will
'
be required to support operation after startup.
~
The sample line to monitor RM-A3, Auxiliary Building Exhaust e.
Duct Monitor, appears to be installed with line bends of shorter radii than specified in the installation drawing, which requires a bend radius of 10 feet. A licensee represen-tative acknowledged this condition and stated that it already had been identified as a problem for correction.
6.
Periodic Calibration of Meteorology Facility
'
a.
This item was originally discussed in IE Report No. 50-302/75-
2, Details I, paragraph 4, and dealt with the lack of proce-dures for the quarterly calibration of the meteorology facility.
The item was closed as discussed in IE Report No. 50-302/75-
!
19, Details III, paragraph 6 with the issue of Surveillance Procedure SP-158. At the time of issue, SP-158 was issued as a temporary procedure. A licensee representative advised the
!
inspector that the procedure had been revised, reviewed by the Plant Review Committee (PRC) and approved by the plant manager and was officially issued, removing the " temporary" classifi-
-
cation.

The inspector reviewed revision 2 to SP-158 and determined that it had been reviewed by the PRC and approved by the Plant l
Manager. The inspector also reviewed the PRC minutes for meeting 76-30 and verified that the procedure had been reviewed
-
with no comments or changes. The inspector had no further questions on the procedure or on this item.
