12.5.2.2 Facilities A.
Health physics facilities at the MNP-2 plant include the following:
Two locker-change rooms are located in the Service and Radwaste Buildings, respectively.
These rooms are provided with lockers for personnel clothing storage, clean Protective clothing supplies, and respiratory protective equipment.
Personnel decontamination showers and sinks are located in the Radwaste Building (487'evel) locker-change room.
Temporary change areas are set up as necessary in other areas of the plant to localize and prevent the spread of con-tamination while performing maintenance activities.
Smaller inven-tories of protective clothing and respiratory equipment are also stored in the emergency relocation centers, operation and radwaste control
- rooms, and strategic locations throughout the plant.
2.
Personnel and equipment monitoring stations are provided at the radiological access control area and various posted areas within the radiological access control area to survey for radioactive contami-nation prior to exiting.
Monitoring equipment includes low level smear counters, hand and foot monitors, and/or portable personnel monitoring equipment (friskers).
3.
Medical first aid facilities are equipped to provide care for injuries, including those with radioactive contamination involved.
4.
Facilities for equipment and tool decontamination exist in the Rad-waste Building, Turbine Building, and Reactor Building.
The loca-tions and facilities are:
a.
Radwaste Building The general decontamination area is shown in Figure 12.3-1, approximate column location g.l-13.2, at the 437'0" level.
Facilities include curbing, sink, monorail, hoist, and drains.

o
At the 487'0" level, Figure 12.3-5, column coordinates R.2-14.0, tools and small equipment can be decontaminated.
Facilities include an ultrasonic cleaner, sink, bench
- space, and drains.
b.
Turbine Building Figure 12.3-1, columns H-9.5, elevation 441'0", identifies the Turbine Building decontamination area.
Facilities include a
monorail, curb, sink, shower, and drains.
c.
Reactor Building The head washdown area is shown in Figure 12.3-4 at column
'oordinates N-5.8 at the 606'10" level and contains a curb and drain.
The CRD room area, Figure 12.3-3, columns M-3.4, 501'0" eleva-tion, contains curbing, sink, monorail, bench, storage
- racks, and tables.
An additional small decontamination area exists at the same elevation, same figure, at K-8.3 and has curbing, sink, bench
- space, and shower.
d.
The Health Physics/Chemistry Supervisor's office is located in the Service Building.
The Health Physics Supervisor and Health Physics/Chemistry Technicians are located in the Radwaste and Service Buildings, adjacent to the locker-change rooms.
These locations provide for ready access to the radiation protection staff by other plant workers and an area to generate and store all records.
e.
A hot machine shop and a hot instrument shop are provided in the Radwaste Building for work on contaminated equipment under controlled conditions.

f.
A laboratory complex is provided in the Radwaste Building, consisting of a sample room, hot radiochemistry laboratory, and a counting room where radioactive samples will be qualitatively and/or quantitatively analyzed.
B.
Health Physics Facilities at the Plant Support Facility/Emergency Operation Facility (PSF/EOF) 1.
The PSF/EOF facility is designed and performs as a supplement and service provider for many plant functions:
among these are health
- physics, chemistry, and other monitoring and analytical operations.
A description of the PSF/EOF functions, including area
- maps, during emer gencies is located in Chapter 13 of the FSAR.
The health physics/chemistry functions at the facility are directed by Radiological Program Instructions.
These are procedures that implement NOS-38 and are in concert with the Plant Procedures Manual.
Transpor ting of radioactive materials to and from the PSF/EOF and the plant is under the direction of PPM 11.2.14.8, "Transfer of Radioactive Material Between Facilities," and RPI 12.37, "Receipt,
- Storage, Transfer, and Disposal of Radioactive Material and Laundry Between Facilities."
2.
An instrument calibration laboratory is located at the PSF/EOF, performing calibrations and repairs on plant instruments, including those used by the Health Physics Department.
The lab is located on the first floor, at the extreme northwest section of the facility.
Mall thicknesses for the source storage cubicle (labrinth) are 2'hick, with 2'hick concrete ceilings.
A high-radiation locked gate provides positive protection for the source storage cubicle where larger open sources are used and stored.
In addition to performing calibration and repairs, the Radiological Programs Department administers contracts for items sent to quali-fied vendors for calibration and repairs.

Where applicable,
- sources, test equipment, calibration devices, and other such equipment are traceable to the National Bureau of Standards and other recognized standards laboratories.
The sources used in this lab range from the Cs-137 approximately 200 curie source hous'ed in the Eberline Model 1000B calibrator, a 20 curie Americium Beryllium neutron source houded in a T.L. Shepherd Model 149 calibrator, to a one mCi Cs-137 source."DA well is also located in the lab to house a 1000 curie Cs-137 source in the future.
Calibration operations are directed by the Radiological Programs Instructions (RPIs) as required to support plant operations.
3.
A chemistry and radiological counting laboratory is located on the first floor of the PSF/EOF facility.
The chemistry lab has HEPA filtered and monitored fume hoods which are located against the laboratory's perimeter walls.
The lab is designed to perform analyses on samples with environmental level to post accident level activities.
Personnel traffic patterns are instituted for positive radiological control.
Personnel, area and atmospheric radiation monitoring,:.

and sampling devices are employed in the lab when riecessary.
Lab sinks are piped into a monitored sump (liftstation) and processed by the'anitary sewage systems per 10 CFR 20.303.
4.
A laundry and respiratory mask cleaning facility is housed in a dedicated building employing commercial grade equipment and applying radiological standards and practices for safe operation, personnel protection, area cleanliness, and process control.
These include:
o Positive personnel and material traffic routes.
o Employing HEPA filters in the gaseous effluent paths.
o Sampling and monitoring the effluent downstream of the HEPA

o Sorting and segregating incoming laundry according to types of materials and radioactive levels.
o Employing stationary,
- portable, personnel and atmospheric radi-ation monitoring equipment for process safety and personnel protection.
o Per RPI, conducting of routine area surveys of the facility to ensure cleaq work areas.
5.
A dosimetry laboratory and whole body counting laboratory are located in the PSF/EOF.
These labs distribute, recycle, and process the thermoluminescent (TLD) personnel dosimeters and provides inhouse internal dose assessment for all Supply System facilities and environs.
It regularly participates in badge sharing (cross referencing) programs with other laboratories as available.
Pre-determined numbers of badges are irradiated (spiked) at MNP-2 and read at the PSF/EOF lab periodically to ensure equipment and tech-nique proficiency.
TLDs used for official dosimetry records are exchanged and read, as a minimum, on a quarterly frequency.
6.
A respiratory equipment test facility,is located, at the PSF/EOF, providing quantitative man-fit testing and maintaining the official records.
