ALARA Considerations a.
In RII Report Nos. 50-369/78-14 and 50-369/79-12 several concerns were l*
fied relating to arrangement of demineralizers and associated p-d other identified problems related to reducing occupational
, _...es.
In response to a meeting held on January 5,1979 between NRC officials and Duke Power Company, a letter, dated March 21, 1979 from Duke Power Company to Region II delineated responses to specific concerns relating to ALARA considerations of the demineralizer arrange-ment and associated piping.
Several of the items were previously reviewed and discussed in RII Report No 50-369/80-2, paragraph 3.a.

supervisor and toured the various areas to observe the status of the changes.
The following is a summary of the previously identified
'
ALARA considerations:
.*
(1)
(78-41-03) ALARA Review of Mixed-Bed Demineralizers and Resin Batching Tank.
(Closed) Two items in this room remained open:
provisions for temporary shielding and the removal of Lydraulic snubbers.
The inspector observed that the temporary shielding hooks were installed in the NV
"B" demineralizer room and were being installed in other rooms. The inspector also observed that the hydraulic snubbers had been replaced with mechanical snubbers.
(2)
(78-41-04) Straight Elbows in Resin Lines (Closed) The inspector observed the sluice lines from the spent resin storage tank and determined that the elbows had been re-placed by large radius bends per the Duke Power Co.
letter of March 21, 1979.
(3)
(79-12-03) Spend Resin Sluice Pump (0 pen) The inspector observed that the piping and valve location modifications had been accomplished but that no shielding had been installed.
The inspector discussed this with the cognizant supervisor, who stated that the design of the shielding for the pump and piping
.
was still being investigated.
(4)
(79-12-04) Volume Control Tank Room (Closed) The hydraulic snubber in the room was replaced with a mechanical snubber as stated in the Duke Power Company letter of March 21, 1979.
'
(5)
(79-12-05) Spent Resin Storage Tank B Valve Room (Closed) The inspector observed that the piping header and transfer line had been relocated outside of the valve room.
(6)
(79-12-06) Inaccessible Filters (Closed) The inspector observed that piping interferences and structural members had been relocated to provide access to the filter horsing from the overhead access plug.
Clearances were confirmed using a flashlight to check for interferences by projecting a beam upward to the plug; no inter-ferences were found.
(7)
(79-12-07) Modifications to Piping in Demineralizer Rooms (Closed)..
Piping in the rooms has been rerouted to move valves outside of the demineralizer shield and the flush valves have beda relocated outside of the rooms in a shielded area.
l (8)
(79-12-08) Activity Measurement Access in Hatch Covers (Open).
Several shielded hatch covers have been modified to provide an access for a radiation survey instrument probe.o be lowered into the room; the remainder of the covers will be modified, according to the cognizant supervisor.

(79-12-09) Shielding of Filter Housings (Open) The inspector discussed the installation of the shielding with a licensee representative, who stated that the shielding for the filter housings was being fabricated but had not.been delivered or installed.
c.
Items 78-41-03 and 79-12-04 includsd concerns regarding the installa-tion of hydraulic snubbers in high radiation areas, due to periodic surveillance and test requirements in the Technical Specifications, which could result in high personnel exposures.
In accordance with the Duke Power Company letter of March 21, 1979, the hydraulic snubbers were replaced with mechanical snubbers.
Subsequent to this change, surveillance requrements for mechanical snubbers were added to the Technical Specifications; consequently, personnel exposure during periodic surveillance of mechanical snubbers is still a concern. The inspector discussed this condition with licensee representatives concerning possible removal / relocation of the snubbers or requesting
)
an exemption to the Technical Specifications surveillance requrements for these snubbers due to the inaccessibility and potential high radiation levels. A licensee management representative acknowledged this and stated that it would be reviewed further. (80-21-01).
6.
Preoperational Test Results a.
The inspector reviewed four completed preoperational test procedures.
The review included verification of proper review and approval of changes, review and approval of the completed test per FSAP Section 14.1.1.5, identification and correction of identified deficiencies,
,
completed results and retest as appropriate after deficiency correc-
]
tion or modification. One minor discrecancy in recording corrective action in a deficiency log was noted; however, the ter.t procedure and test log showed that this deficiency had been corrected and tested. A licensee representative stated that the deficiency log would be corrected The inspector had no further questions.
.
b.
Test procedu. es reviewed were:
(1) TP 1/B/1500/02, Liquid Waste Recycle System Preoperational Test.
(2) TP 1/B/1500/03, Liquid Waste Monitor and Disposal System Preoperational Test (3) TP 1/B/1500/05, Liquid Waste Evaporator Preoperational Test (4) TP 1/B/1600/01/B, Area Radiation Monitoring System Functional Test.
7.
Radioactive Liquid Waste System Addition a.
In RII Report No. 50-369/80-12, paragraph 6, the radwa.;te addition was discussed and open item 80-12-02 dealt with the need to revise the FSAR to include the addition.
Change 39 to the FSAR included a des-cription of the facility and equipment specifications for major component..

"ovever, the syatem drawings have not been revised to show the radwaste addition piping systems or the interties with the existing systems.
The inspector informed licensee management that the open item was still open pending revision of the drawings.
b.
The inspector observed the installation of the Scility exhaust air monitor and sample line installation. The sample line has one sharp 180 bend and 3-90 bends immediately adjacent to the sample probe and a long, horizontal run to the monitor. The condition is unsatisfactory for the sampling of particulates in the exhaust. The cognizant super-visor acknowledged that the sample line installation is unsatisfactory and stated that a work request would be initiated to rerun the sample line and that relocation of the monitor would be investigated to place it closer to the sample point. (80-21-02)
c.
The inspector compared the nameplate data with Table 11.2.3-1 for the auxiliary floor drain tank pump and the auxiliary waste evaporator j
feed tank pump and noted that value listed on the nameplates for the j
head at design flow was different from that listed in the FSAR. While
this value may be acceptable, it should be reviewed.
A licensee management representative stated that this would be reviewed, and the FSAR would be revised. [80-20-03]

Station Health Physics Manual
'
a.
RII Report Nos. 50-369/77-9, 50-369/78-19 and 50-369/78-36 discussed the need for issuance of the Health Physics Manual required by FSAR j
Section 12.1.5., inclusion of certain policy statements in the manual i
and inclusion of a statement on the authority of the Station Health Physicist.
The station Health Physics Manual was approved by the Station Manger on March 27, 1979.
The inspector reviewed the manual
'
and verified that it included the policy statements and statement of authority. Additionally, the System ALARA manual was issued in February 1980, which includes a statement of responsibility of the station Health Physicist. The inspector had no further questions.
b.
Open Item 80-02-07 dealt with the revision of the respiratory protec-tion policy statement to include topics required by Section C.1 of Regualtory Guide 8.15.
The inspector discussed this revision with the cognizant supervisor, who stated that the revision had been prepared and reviewed but was not yet approved. The inspector stated that open Item 80-02-07 remains open.
9.
Ventilation in Hot Machine Shop RII Report No. 50-369/77-9, paragraph 9.a.(2) discussed the need for providing exhaust ventilation at or near the machines in the hot machine shop due to-the potential for airborne radioactivity. The inspector toured the hot machine shop and observed that the exhaust ventilation ducts had been modified to provide for the attachment of temporary exhaust ducts (" elephant trunks") which can be located at the various machines. A licensee repre-
