records of liquid and gaseous effluent releases made during the period from
January 1, 1985,
through May 1, 1985,
that the records required by the
Technical Specification were retained in terms of frequency and content and
were accessible for recall and review.
No violations or deviations were
identified.
13.
Post-Accident Sampling System (PASS) Evaluation
The H. B. Robinson facility PASS was designed and built by Combustion
Engineering. NUREG-0737,
Item II.B.3 established eleven criteria for the
PASS. These criteria specify types of samples to be taken, sampling times,
types, accuracies, and sensitivities of sample analyses, radiation dose to
operators,
and design
consideration.
The inspector evaluated the
H. B. Robinson facility PASS against the eleven criteria.
Through review of. selected records,
observation of sampling equipment
operation, discussions with licensee representatives, and inspection of the
installed system, the inspector verified that the PASS criteria have been
met except as noted below.
a. NUREG-0737, Item II.B.3, Criterion (1), states that the licensee shall
have the capability to obtain and analyze reactor coolant and contain
ment atmosphere samples within three hours.
The licensee demonstrated
the ability to obtain reactor coolant and containment atmosphere
7
samples and to complete the analysis of each within a three hour time
period.
b.
Item II.B.3 Criterion (3) states that PASS samples shall
not require an isolated system to be placed in operation in order to
use the PASS. The reactor coolant and containment atmosphere post
accident sampling systems are designed so that no isolated auxiliary
system is required to be placed in operation in order to use the PASS.
c. NUREG-0737, Item II.B.3, Criterion (2b) states that the licensee shall
be able to measure hydrogen levels in the containment atmosphere. The
licensee has two redundant safety grade hydrogen analyzers in service
at all times. These instruments are separate from the PASS and do not
require any other system to be in service for operation. The analyzers
were operated and were able to draw samples; however, no hydrogen was
present in the containment atmosphere and sample results showed zero
readings.
Both analyzers had been satisfactorily calibrated against
known concentrations of hydrogen gas.
d. NUREG-0737,
Item II.B.3, Criterion (6) states that personnel shall be
able to obtain samples from the PASS and not exceed a radiation dose of
5 Rem whole body or 75 Rem to the extremities.
Evaluations of dose
rates at the PASS control panel were made by both the licensee and the
system vendor. Both evaluations concluded that samples can be taken
without exceeding
the specified doses.
However,
the inspector's
examination of these evaluations indicated the following:
(1) The shielding studies included in the evaluations apparently did
not include RCS and containment atmosphere sample piping external
to the PASS panel.
The areas of concern are the rear of the PASS
panel, where brief personnel access is required for the operation
of one manually-actuated valve, the "pipe alley" adjacent to the
PASS panel, and the reactor auxiliary building access hallway.
(2) Doses from a two foot long section of a reactor coolant sampling
line have apparently not been evaluated with respect to direct
radiation from an unshielded line-of-sight path to the hallway in
front of the
operating panel.
The licensee agreed to
evaluate these concerns.
This inspector followup item will be
reviewed during a future inspection (50-261/85-15-01).
Revision 3, recommends analyses for pH.
The
licensee measured the pH of the reactor coolant with the following
results:
Normal Sample Point
pH
6.3
6.4
8
f.
NUREG-0737, Item II.B.3, Criterion (8) states that if inline monitoring
is used for any sampling and analysis capability, the licensee shall
provide backup sampling, through grab sampling.
The licensee demon
strated the capability to take and analyze both a diluted grab sample
and an undiluted grab sample of the reactor coolant.
A diluted grab
sample of containment atmosphere was also obtained.
These samples
demonstrated the capability to back-up the inline analysis equipment.
g. NUREG-0737,
Item II.B.3, Criterion (2a)
and Criterion (9) state that
[1] the licensee shall provide onsite radiological analysis capability
to quantify noble gases, iodines,
and nonvolatile radionuclides in
reactor coolant and containment atmosphere that many be indicators of
core damage, and [2] the sensitivity of onsite liquid sample analysis
capability should permit measurement of nuclide concentration in the
range 1 pCi/g to 10 Ci/g.
The licensee sampled and analyzed reactor
coolant samples with the following results:
