will be used as the receiving ward. Near this receiving room j
is a locked metal cabinet which contained the emergency supplies for handling contaminated patients. The following items were
,. -
included in these supplies:
half face and full face respirators, plastic sheeting, protective clothing, labels and signs and survey and monitoring ins.truments. A training session for nurses and other interested hospital employees was conducted on May 21 by SMUD and responsible hospital personnel. An exercise, involving a dummy containing very small sealed i
j sources and a small amount of contamination, was performed at the hospital on June 5.
The dummy was transported to the
'
hospital in the SMUD emergency personnel carrier and emergency

vehicle.
b.
The licensee stated that arrangements have been made for two doctors in the local area to provide on site medi:al treat =ent of personnel. Also there are provisions for requesting an O
ambulance through the Gault Fire Department. however, the
'
licensee's emergency plan directs that use of the site emergency vehicle be given first consideration.

.
I ties in times of emergency at the plant..According to the SMUD emergency plan, the initial call for assistance would be to the Sheriff's Department office. The Sheriff's Department representa-
.
tives said that they would be responsible for the init.ial closure
{
of the roads around the Rancho Seco area and evacuation of the public. They also noted that with respect to closing the roads, it would be expected that the California Highway Patrol would relieve j
i the Sheriff's Department personnel of this responsibility when the
'
Patrol officers arrived. The Sheriff's Department has develg ed a set of procedures pertaining to actions required.by an emer9ncy at the Rancho Seco site. The Watch Coc:mander has a copy of v.tese procedures. The Sheriff's Department representatives briefly

d)
During the June 10-11 inspection the flushing procedures for the coolant and miscellaneous liquid radioactive waste treatment systems-y were examined. Also examined were the test procedures for the high
,.
efficiency particulate (HEPA) and charcoal filters. The format for
- .
these procedures was found to be as described in paragraph 7.a of
?*
report No. 50-312/74-(2. The examination of the test results of the new and spent res:n transfer system showed it functioned as intended.-

Filter Testing
,
i On June 20, 1974 the testing of the HEPA filter in the cmtrol room emergency ventilation system with diocty1phthalate (DOP) was observed.
The DOP smoke was created by a ther=al generator, Model TDA-5A, a
. fabricated by Air Techniques, Inc. The detector, Model TDA-2C by l
Air Techniques, Inc., was last calibrated on January 24, 1974.
Samples.were collected i= mediately before the HEPA filter and after
j the charcoal filter. The sample collection device was a. 3 inch q
diameter metal tube with 3/16 inch holes spaced 1-2 feet apart.
The DOP was inserted sufficiently ahead of the initial sampling
,
j location to assure mixing of the DOP with the air. According to N
the individual performing the test, these same injection and sa=ple
)~
removal locations were to be used for the charcoal filter testing (using Refrigerant 11)..The initial test of the HEPA filter showed leakage in excess of the acceptance criteria (less than or equal to
0.05%) shown in the test procedure. Examination of the HEPA filter disclosed the clamping mechanisms were loose. The cla=ps were tightened and silicone sealant was placed on some of the metal frames at the point where filters made contact. A retest of the HEPA filter showed that the leakage (0.08%) was still in excess of
the criteria. Additional work was to be performed on the filter before the test would be run again.

Radiation Control Manual and Emergency Plan
.
a.
During the period April 1 -- May 20,1974 the Radiation Control Manual was examined. The =anual has been divided into three sections: General Information, Control Measures and Proce:ures.
i
!
The responsibilities for radiation safety are assigned in the first section.
The bases for the radiation standards and control measures, and the maximum permissible doses and concen-trations are discussed in the general information section.
The control measures section includes the M 1owing topics:
control of access to the restricted area, external radiation i
dose reduction, radiation dosimetry, contamination and allowable
'
pT limitz,, respiratory protection, radiation detection equipment
~' d (portable, area and process monitors), a radiation work permit i

-6-system, receiving and shipping of radioactive materials,
'
radioactive waste control, and reporting requirements. The
'
procedures in the third section contain the detail instructions
for implementing'the requirements contained in the first two I
sections. The-licensee stated that an additional document
'!
covering the training, fitting, use and maintenance'of respira-
.j tory equipment was still to be prepared. No topics or require-
.
ments that should have been covered and were not were identi-fied during the examination of this document.
"
b.
During the period April 1 - May 20, 1974 the Emergency Plan was also examined. This' plan is divided into a general informa-tion and a procedures section. The operating and emergency
organizations and the assigned responsQ 111 ties for the.latter
.l have been described in the general section. Also included in j
the general section are the following: a description of the spectrum of accidents covered by the plan, the off site support
,
,
groups and the service provided, the communications sytems at
the plant and the in plant warning devices. The protective
'
measures to be taken and the action levels have also been
' covered in the first section. The procedures have beca divided into four types of accidents:
injury, overexposures, fire and sabotage. There are procedures for local (area), plant and
. general population evacuation in this second section.
.
The plan requires quarterly evacuation drills. Emergency communication equipment are to be tested during the quarterly drills. Annually there will be a drill involving the use of the SMUD emergency vehicle and the Sutter Hospital staff. The plan provides for training of personnel in the areas of first
"
aid, fire and radiation safety. There are provisions to
.,,
assure periodic review of the' emergency plan to assure it is
-
kept current. The only deficiency in the, plan identified during the examination was incorrect information, in the notification sections, for the Regional AEC Regulatory Operations r
office and possibly the State Department of Health (Radiologic
-
Health Section). Modifications to the plan require prior approval of the Plant Review Committee.

Fire Assistance
,
The licensee has arranged for fire assistance to be provided by the
Herald Fire Department. According to the licensee, members of the l
Herald Fire Department visited the site on June 16, 1974 and made a tour of the facilities for the purpose of learning the locations of
~ fire protection devices and equipment. They were also shown movies
,
pertinent to fighting fires at nucicar facilities. The Herald fire
,
equipment was connected to the plant water connections to assure
,
i compatibility.
The first connection did not function properly, L
.
however, the second connection operated as intended. The Herald i,
