REASON FOR SO FEW CATEGORY I HEDS The initial design review of the SHNPP-1 Control Room was conducted from April 1980
~
~
~
to 3anuary 1981.
During the April to 3une period the MCB was reviewed using layout drawings and the simulator. A total of 130 discrepancy reports (pre-NUREG/CR-1580 and pre-NUREG-0700) were written: 09 against the MCB and the remaining against component and environment based on the simulator.
These 09 discrepancy reports concerning the MCB addressed grouping and sequencing problems (the only feature that could be adequately addressed on drawings).
The reports were written at the system/sub-system level and, if written in today's NUREG-0700 environment would result in substantially more HED reports.
As an example, what is now the charging and letdown "systems" (or sub-systems) on the lA2 section of the MCB, originally had their related controls and displays interspersed with each other such that these separate functions could not be visually separated nor easily operated.
There were r
approximately 20 dislocations of controls and.'12 to 15 dislocations of displays from what was considered an acceptable arrangement.
Some of these dislocations were grouping I
and others were sequencing problems.
This example would be typical of the 09 system
~

~
~
level reports.
As'can be determined, if written on a basis that documented an average of five components'per HED (a reasonable number of components on an arrangement problem involving both controls and displays) there would result approximately 300.or more HED reports.
As has been reported in past documents, letters and Section 3.0 of the Final Summary Report, CPRL's re-design approach was to eliminate, if possible, the identified problems before attempting to categorize or prioritize them.
Taken in light of the absence of any reasonable HED assessment techniques in the mid-1980's, this was an acceptable and expeditious approach.
However, this approach precluded an attempt to accurately establish the number of highly significant problems as opposed to the trivial ones, as the 09 identified system level problems were adequately eliminated in the MCB re-design effort.
The 09 sequencing and grouping HEDs were categorized in 1985 when all the other HEDs were assessed.
Because all of these 09 HEDs had been corrected during the MCB rearrangement, the HEDAT assessed each of the HEDs individually without addressing
{5705AWS/ccc )
interactions between them. It was felt that a fullassessment of these HEDs for interactive issues of safety significance would not be meaningful since the components were rearranged during re-design.
The rearrangement eliminated the pre-existing interactions. It is quite possible that a number of the interactions would have resulted in a Category I classification.

Spent Fuel Rack Lifting Rig CPIIL does not intend to routinely rearrange the spent fuel rack modules within the pools.
Even when the rack modules are lifted it is very unlikely they will be lifted over spent fuels However, if the occasion should arise where it is necessary to liftmodules over spent fuel, the spent fuel rack lifting rig will be static load tested to 150 percent which includes a factor of 25 percent of static load to account for dynamic
- loads, Internals Lifting Rig - The internals lifting rig is
- designed, tested, and fabricated to lift both the upper and lower reactor vessel internals.
The lower internals are the design lifting weight for the internals lifting rig.
The lower internals weight approximately 202,500 lbs.
The lower internals will never be lifted over spent fuels The upper internals are lifted each refueling outage (or any time access (3752JDKa/ccj
)
P SECTION COMPLIANCE/EXCEPTION is required to the fuel within the reactor vessel)
~
Thus, the maximum critical load for the internals lifting rig is the weight of the approximately 93,200 lbs.
The internals lifting rig has been tested and certified by Westinghouse to 345,000 lbs.
Additionally, CPS,L has performed analysis demonstrating that a drop of the upper internals (with the internals lifting rig and the crane block attached - an additional 45,000 lbs.) results in no fuel damage or loss of core cooling.
Therefore, when the upper internals are lifted, the lifting rig experiences only 46 percent of its design lifting weight and only 27 percent of iis tested capacity.
Additionally, the internals lifting device will be ittested<< at approximately 217 percent of the upper internals weight each time the lower internals are removed from the reactor vessel in preparation, for the normally scheduled reactor vessel inservice inspection.
This >>testtt is more than adequate to ensure the continued integrity of the lifting rig for lifting the upper internals, Based on the above stated conservatisms in design (both hardware and analytical ), periodic testing of the lifting device Hill not add to plant safety, CPE,L will, however, inspect the lifting device prior to use for visible degradation (rusting, pitting, etc,),
Also, the lifting rig Roto Lock mechanism will be functionally checked on a periodic basis (each refueling outage prior to lifting the upper internals) ~
