2.0 APPUCABlWTY/ SCOPE This procedure is applicable to aR Tech. Spec. quarterly inspections performed at the Saxton Nuclear
-)
Experimental Corporatkm (SNEC) facity.
DEFINITION 8 None 4.0 PROCEDURE 4.1 Discussion 4.1.1 At least two (2) people, one of whom wil be a quaillied Radiological Cuarols Techmcien, wBI l
make the inspection.
i 4.1.2 The inar=*wn wW be made in accordance wth this procedure and Ref. 6.7 j
4.1.3 if any of the locks, doors, or gates inspected are found open, or appser to be tampered, i
Ref. 6.3 shall be implemented as appropriate i
4.2 Accaretus

4.4 Perform facElties check as outlined in Exhbit 1, Part 1.
Send contamment sump and CV pipe tunnel water samples for appropriate analysis Water-4.4.1 samples are requred to be analyzed for groes beta gamme activity and for the isotopic j
concentration of an signecent radionuclides.
4.4.2 The use of the TMI Chemetry results are for quality control purposes only. A split GA I
sample for TMI Chemistry wEl be taken of CV sump water. Reguistory reporting of results from TMI Chemistry can only be used it: 1) other sources of analysis are not avalable, and l
- 2) the results must as a mmimum have an LLD consistent with 10 CFR 20, Appendk B, Table 2. Column il concentrations,3) and/or approval of the SNEC General Manager.
4.5 Performance of the Ouarterty Containment Vessel Survey This survey is intended to trend the migration of the contamination within the containr.ient structure, l
to verNy does rates, to sample the CV sump if poselbie and change out the high officency futer on j
the containment vessel breather tube.
NOTE 1
i The breather tube akms for an exchange of air between the outside air and the containment environment. The high offidsney futer is in place
[
to fBter particulate metter, 4.5.1 Before opening the CV outer door caN the Diaparch at (814) 535-6466 State your name and inform them you are about to make a Contamment Vessel entry.
4.5.2 The twenty fixed point locations (see Exhibit 2) serve as the location for general area beta gamma does rates and contamination survey points. These locations are also posted inside containment. At each location a general area beta-gamma does rate and smear sample are to be taken. The RO-? is the preferred instrument for does rate measurements.
In addition to the flued point locations, random does rates and smears should be taken.
Five to ten random locations are suggested. Radiation and contamination surveys to be done in accordance with Ref. 6.4 and Ref. 6.5. Exhibit 1, Part 2 shall also be fBled out for the ftxed point survey resuka 4.5.3 The breather tube futer shal be changed out and surveved quarterfy. Contact the SNEC RSO to ensure the availablity of replacement fBters.
4.5.3.1 To replace the fIter, loosen the wing nuts and remove the retaining plate.
i 4.5.3.2 Remove the used filter.
4.5.3.3 Bag the used fIte* and visuaNy inspect the breather tube port for any obstructions
- i 3
4.5.3.4 instal the new filter, replace the retaining plate and tighten the wing nuts.

4.5.3.5 Romme fRter to low background area and survey for unrestricted release. When filter is redged for unrestricted use t is to be forwarded to a laboratory for gamma specu%f. Contact SNEC RSG for help in notWying applicable lab and/or initiating sample coEection sheets. FIter gamma spec results are to be maintained with Exhibit 1 for each quarterly survey.
4.5.4 Checking the CV Sump Level and Taking the Sample 4.5.4.1 Proceed to the 812' elevatkn of the Containment Vessel (See Map, Exhibit 2).
Unlock and open grating. Note you are entering a posted, locked, high rad and step off pad area. Proceed down the stairs to the basement level, go around the shield wall. The CV sump is near the Rod Room door. Verify the Roo Room door is locked and document on Exhibit 1.
NOTE Exhibit 3 shows a cross section of the Containment Vessel and the sump location.
E 4.5.4.2 Measure the water level of the sump. Document water level on the appropriate line on Exhibt 1.
4.5.4.3 Use the hand pump prwided to pull two,500 mi samples. Rinse each sample bottle and cap wth the sump water prior to taking the sample. The required sample ar":mt can vary so contact the SNEC RSO for the necessary sample volume.
NOTE The sump sample actMty typicaNy requires that the TMI Wasta Disposal Group package and ship the sample to the applicable labs for analysis.
Contact the Waste Disposal Group to arrange support.
4.5.4.4 Take appropriate measures to ensure the sample (s) are less than 1000 dpm/100 2
cm for smearable, extemal betagamma contamination for rernoval from the Containment Vessel. If the Waste Disposal Group representative is present, tum the sample (s) over to him/her for processing. If the indMdual is not present the samples are to be staged where appropriate and posted per the requirements of Ref. 6.6 unt8 the samples can be packaged and shipped.
4.5.5 A general area radiation and contamination survey should be documented to support the entry into the lower elevations per References 6.4 and 6.5.
4.5.6 Secure all locks, doors and gates and notify Dispatch again when the outer CV door is secured.
4.5.7 Ensure Exhibit 1 is completed and forward al survey results to the SNEC RSO for review.

4.6 Fence Survey 4.6.1 A radiation survey shall be performed around the outside of the SNEC sto fence, the Containment Vessel (exclusion area) fence, common SNEC/Penelec fence (s), and the Penelec outer fence which describes the limts ct the SNEC /Penelec line shack property The survey shall consist of general area dose rates. As a minimum, an instrunant wth uRom/hr senskMty shall be used for this survey. Highest general area dose rates are to be filled in on Exhibit 1, Part 2. Readings should be recorded on Exhibits 4 and 5 or equivalent forms, as appropriate.
5,0 RESPONSIBlWTIES Inspections shad be conducted no less than once per calendar quarter. The Saxton General Manager or designee is responsible for ensuring that the quarteriy inspections are conducted according to this procedure. Technical Specification violations shah be reported to the SNEC Ucensing engineer or his/her designee, W is responsible for notifying the NRC in accordance wth Tcchnical Specification Section B.S.a.
